From: Sleddog
Subject: roller camshafts

i think i remember some people talking about roller cams a while back. i
am now looking at getting a roller cam too. but, so far searching has come
up with the smallest one being about 280 .050 and .570 lift. this may suit
my needs, but according to the desktop dyno runs best at 6000-8000. 6500
is all i really want to run, 7000 is pushing it, so i need a "smaller" cam
to deliver the power earlier on.

but this is the question. has anyone out there installed a roller in a 460
before? do the crossbars on the lifters clear without modification and do
i need to do anything to the front of the block or cam chain cover? i know
i need a bronze gear, and maybe different pushrod length. also, do i have
to do anything to the oiling sytem like restrict it?

i need max power, but can't afford to redo the bottom end (like flycut
pistons for the valve clearance.) smaller roller would be better, but i'll
live with the one i found if i can fit it in there without modifications.
i will be doing this with engine in truck, so i don't want to grind the
block or stuff like that to get it to fit.

any help is appreciated.

I'v had new floats leak, so check them out.

Have you checked the needle and seat carefully?

What pressure are you running? Holley's don't like anything much over 2 1/2

Over rich idle mixture IMHO. Put a light on it at idle with the vac
hooked up. If you're at ported vac then you will see initial
mechanical timing but if on manifold it should be around 40.

You could have any of several problems but it sounds like the idle
mixture or plugged or damaged carb, leaking float needles etc.. All
these problems go away when you open the throttle even a little bit
usually.

What carb is on it?

Subject: RE: Timing causing engine vibration and poor emissions?

Actually I would suggest checking the plug wires with a voltmeter or
checking to see if you fouled a plug or something. I have had this
condition (rough idle, smooth at higher rpm's) and found the secondary
ignition system to be the culprit. =


Just a suggestion. Hope this helps.

I know a few weeks back there was some discussion (which I found quite
interesting and helpful) on vaccum advance/retard on distributors to bett=
er
tune engine timing at different RPMs. Does this seem like a worthy
postulation?

BTW, I'm pretty new at this stuff, but eager to get my hands dirty.

77 460 with vaccum advance/retard distributor setup, its currently runnin=

revving engine shows smoothness of engine and loss of vibration with the
pedal slightly depressed all the way to the floor. Thus, idling and low
rpms seem to produce engine vibration. If the timing were correct when

Anyone think I just might be on right track? Any other suggestions?

Subject: fouling one plug

My # 1 spark plug is fouling. I checked for a vacuum leak around the intake
manifold near # 1, vacuum at idle (800rpm) from the lower port on carb read
17-18 in. of vacuum before and during a liberal dousing of Gumout. Any other
ideas?
Let me give you all my details:

- -`72 or `73 460 with `68 429 non CJ heads.
- -Offenhauser 6" rise, single plane intake
- -Holley model 3310 750cfm, vacuum secondaries (brand new)
# 72 main jets, # 75 secondary jets, 6.5" hg power valve, # 31 accel pump
nozzle
- -new dist. cap & rotor (electronic ignition)
- -new plug wires
- -Bosch Platinum plugs gapped to .44"

I have switched plugs around, and plug wires; problem says with the # 1
cylinder.
Just did a compression check on warm engine, all readings are 180-185 except
# 1= 195, and # 2= 165. Like I said, the carb is new, but I had the same
problem with the old carb ( 800cfm double pumper).
I am completely out of ideas. Any help you can give would be greatly
appreciated.

Thanks,

Oh Man, I'm sorry to hear about Your loss. They get to be like family
after awhile and another old treasure has been lost from the roads.

The alarm and fuel cutoff for my '71 is going back to the top of
the "to do" list. I'll start drawing the schematics tonight. I've already
got the fuel solenoid.
I've also been meaning to install an inside hood release cable, so
You have to get into the cab before You can get under the hood...

Sounds like the theif needs a few more fractures once he's out of
the hospital..!
