Cams are designed to work in a specific relationship to the crank for
best performance and even safety with high lift types. It comes with
the relationship spelled out in degrees relative to the crank TDC
position.

With a degree wheel you can locate the crank TDC position very
accurately using piston stops and set the cam precisely to it's
specified relationship. Bolt the degree wheel on the crank and set
up a pointer for it (that won't get moved by accident), install an
adjustable piston stop (I made some out of old spark plugs and bolts)
in the number one cylinder and rotate gently till the piston hits in
one direction and note the position of the degree wheel, then rotate
the other direction and move the degree wheel to obtain zero at the
pointer exactly centered between the two extremeties (same reading,
plus and minus on the pointer in either direction). Now you can set
the cam using the degree wheel on the crank and the cam's own normal
zero pointer which is up the the cam manufacturer to ensure the
accuracy of.

It can also be used to accurately set the timing tape on your
vibration damper to get accurate specs on the ignition timing :-)

I am getting ready to do the exhaust on my 69 F-100 2wd. with 302 I was
thinking about using 2.5 inch pipe and going from the headers and
exiting the pipe in front of the rear tires like the new Fords. My
question is this is 2.5 inch pipe too big? Will the engine breath too
good? I have heard that you need some back pressure in order for things
to work right. BTW I am running dual exhaust no smog to worry about in

This is a 460 right? Are you using the same distributor with a
replaced pin? Oil pump might turn now but could have stopped for an
instant due to dibris in the pump long enough to twist the drive
shaft and shear the pin and then due to this torque break loose
again. (not likely but possibel) I've seen the varnish from the
inside of the pickup tube come off like parchment or onion skin in a
roll and get lodged between the pump rotors which completely froze it
up and twisted the drive shaft like an ornament. Once it
sheared the pin and, in this case, broke the drive shaft off so the
distributor could turn again just with the light press of the gear on
the shaft the engine kept running till the oil dried up and siezed it
up sitting in my drive way :-(

If the shaft is twisted even a little bit it will also be bent out of
straight so the hex won't fit into the distributor. From your
description I have to guess that this is what's happened.

OTOH, the distributor shaft fits into a hole in the block before it
even gets to the drive shaft and if you cock it even a little it
won't go through the hole but this is theoretical since I've never
had this happen to me before and doubt if it's likely but anything is
possible.

The only other thing I can think of and I'm not trying to be
condescending but just throwing out everything I can think of
(grasping at straws) is that the distributor gear must of course be
lined up or it aint goin in and I can remember times when it didn't
seem to want to cooperate :-)

Subject: Re: Smoggy the Weasel and Pipe Size

Okay, I'll see if I can clear some of this up. First off I don't think
there is any way to get around the need for a cat on my '79 F250 now that
it is flagged as needing one in the system. The engine tag says "Catalyst"
right on it. Darn!! The GVW is only 7700 on my Crew Cab. I think some of
the 4X4 standard cabs with the 460 may have gotten over the 8500 limit and
would be cat exempt. I think that the original equipment called for a air
pump on this one but when the guy at the station looked it up in the book
he said that all I need is the cat to pass. Who am I to correct him! I
also have the UFO printed right on the fuel gauge in the truck but no
labels on the gas fill covers. When I had my '77 4X4 with the 351M it
would have needed a cat but the previous owner had changed to a '75 400 set
of valve covers that said "non-catalyst". The short story is that in the
late '70 it seems to have depended on what kind of a day the crew at the
factory was having as to if you got a cat or not. ;-)

Now then, Gary you said it may be a good idea to go with the 2" pipe off
the exhaust manifold back to the cat. Any reason for this? Sleddog said
go as big as possible. My understanding was that at least a little back
pressure was a good thing. So with two pipes going from the manifolds to
the cat and one pipe going from the cat to the muffler and tail pipe that
of the following two options would you vote for?

1) 2" head pipes to 2.5" cat with 2.5" Flowmaster or Dynomax muffler and
2.5" tailpipe.

OR

2) 2.25" head pipes to 3" cat with 3" Flowmaster or Dynomax muffler and 3"
tailpipe.

Do you have any better (cheaper would be nice) ideas?
Exhausted yet??

Better get the flame suit out for that one!

If the headers are sized right the pipe probably won't be that big of
an issue but 2.5" seems a bit large for a streetable 302 to me. The
460's and other bb like the 351M use 2.5" in stock mode so a built
302 might use all that I suppose?

If you go duals make sure you incorporate a balance tube roughtly 36"
from the ports (in the pipe near the collectors is probably close
enough) and about 2/3 the diameter of the exhaust pipe. It can be
welded in or "T"d in.

You are coming from 4 cylinder to 8 at the cat so the cat should be
bigger than either bank coming into it. Depending on the rpm range
you want to run you will use smaller or larger head pipes. Sleddog
boggs so he wants lots of high rpm power and bigger tubes. For the
street 2" or 2-1/4" should be pretty good and after that I don't
thing it's very important as long as you go bigger so the 3" borla or
one of the other's setups might be a good choice :-)

> Do you have any better (cheaper would be nice) ideas?
> Exhausted yet??

For 2 into 1 setups I tried the Walker more or less stock head pipes
going into a special muffler made for this and out with one pipe.
You may be able to find this setup with the cat but like they say,
get the biggest cat you can fit into the system (diameter wise) to
keep it open and give the least resistance to flow. Cats and
mufflers designed for 2 into 1 are made to separate the banks with
more muffler capacity to obtain "dual" like performance and mine
worked well enough to suit me but was no dragster for sure.

I'm beginning to believe that the head pipes are the most critical
part of the system for performance considerations as long as the rest
is large enough to flow well so for street the smaller head pipes and
for bogging the larger ones.

Sounds like a bad pump. If it's foaming, it's not pumping thru the system.
It's just moving around inside the resevoir. It will probably turn to the
right but not the left without fighting with it. Replace the pump.That should
solve your problem.

The 280 is the light duty series so you might want to use a carefull
foot. I need someone to measure the mounting tabs on the transmission.
How far apart they are from each other and what pattern they are in.
The hardest part would be finding a clutch disk to match because the
clarks use a larger input shaft.

If they use a totaly differt bellhousing someone with a good machine
shop will have to make some adapters. If the spaceer on the bellhousing
is an 1" thick than the flywheel will have to be moved out the same
amount. If the parts are not machined right you will have some nasty
ballance problems. The were used behind FE's, Ford BB, GM small and BB,
and a few oil burners too over the years, so you might want to grab
everything you can with the tranny if you find it, clutch, flywheel,
bellhousing and if it has the t-case adapter you have a real score!

I'd be happy with an extra NP-435 right now but they want $350 and up
for one around here? Either my pilot bearing, input shaft bearing or
clutch is messed up (throw out bearing is for sure) and third gear
really hurts my hand if I hold on to the shifter while gassing it so
the rear end could even be bad along with the tranny but the syncros
still work and it's pretty smooth in high so I'm drivin it :-)

simply, no, it is not too big. go with mandrel bends if you can. since
you are in NC, i guess stainless isn't necassary, but here in PA it is good

(exhaust manifold) has a much greater effect on the engine than anything

Subject: RE: Smoggy the Weasel and Pipe Size

just a small thought, how good are you at cheating? i would never condone
such behavior, but ...
why not get a trashed cat from the scrap yard and gut it out putting a
single length of pipe in the middle so it looks like a cat but is really
just pipe?

anyways, basically, bigger is better. lets say you have a 3" collector, go
3" all the way, or at least 2 1/2. if you have stock manifolds, i'd say a
2 1/2 would work well, but no smaller. mandrel bend if you can, choose a
performance cat or one from a late model that has the big tube diameter (if
the smog nazi's let you do that!). my dodge v10 runs 3" exhaust from
factory, with 2 cats. this motor could use even more breathing room. a
fellow here put a full dual exhaust on his with aftermarket mufflers and it
made a big difference (he said the borla headers he put on also made a huge
difference, while the reprogrammed computer made the biggest difference
with an estimated 550-600 lbs-ft torque) this is 488 cid, not much bigger
than a 460, and the 460 has bigger individual cylinders so each exhuast
pulse is "bigger". in my experience, you loose more by choking an engine
than you will ever loose by giving it the freedom to breath too much. BTW,
a stock cat has much more restriction than using a too small exhuast pipe.
cats also wear out and create even more back pressure. sometimes within
30,000 miles. perhaps a clamped pipe so you can install and remove the cat
as required to pass the visual exam? i wouldn't be surprised if the sniff
test shows more pollution with the cat because of increased back pressure.
if i remember correctly, the pellet type of converter was the one that had
the most back pressure and shortest life.

ok, let me get flame suit, all the alcohol from last night is still with me
and i would go up in a burst like a molatov cocktail!

Okay, I'll see if I can clear some of this up. First off I don't think
there is any way to get around the need for a cat on my '79 F250 now that
it is flagged as needing one in the system. The engine tag says "Catalyst"
right on it. Darn!! The GVW is only 7700 on my Crew Cab. I think some of
the 4X4 standard cabs with the 460 may have gotten over the 8500 limit and
would be cat exempt. I think that the original equipment called for a air
pump on this one but when the guy at the station looked it up in the book
he said that all I need is the cat to pass. Who am I to correct him! I
also have the UFO printed right on the fuel gauge in the truck but no
labels on the gas fill covers. When I had my '77 4X4 with the 351M it
would have needed a cat but the previous owner had changed to a '75 400 set
of valve covers that said "non-catalyst". The short story is that in the
late '70 it seems to have depended on what kind of a day the crew at the
factory was having as to if you got a cat or not. ;-)

Now then, Gary you said it may be a good idea to go with the 2" pipe off
the exhaust manifold back to the cat. Any reason for this? Sleddog said
go as big as possible. My understanding was that at least a little back
pressure was a good thing. So with two pipes going from the manifolds to
the cat and one pipe going from the cat to the muffler and tail pipe that
of the following two options would you vote for?

1) 2" head pipes to 2.5" cat with 2.5" Flowmaster or Dynomax muffler and
2.5" tailpipe.

OR

2) 2.25" head pipes to 3" cat with 3" Flowmaster or Dynomax muffler and 3"
tailpipe.

Do you have any better (cheaper would be nice) ideas?
Exhausted yet??

Better get the flame suit out for that one!

Look at Don Grossman's list and let me know which one you want. The popular
one is the one with overdrive. $250 to $500 depending.

There is a tag riveted on the side of the transmission with the model
number (and other information.)

Subject: re: new problem

Some more thoughts:


1) Did you compare the old dist to the new one. ( shaft length, gear
type and size etc. )

2) Another thought ( and it has happened to me ) is that the dist cap
retainer clips may be pointing down when you are trying to seat the
dist. The one on the drivers side is hard to see. (use a rubber band to
insure they are up and out of the way )

3) Sometimes the one way washer in the oil pump drive shaft that is
supposed to keep the shaft in the oil pump comes off when you remove the
dist. This allows the shaft to come out with the dist. maybe it didn't
come all of the way out of the engine but is sitting on top of the oil
pump. ( look at it and be careful the shaft can fall into the oil pan )....
