Subject: RE: FTE Perf - Exhaust Headers

i was initially going to run my L&L headers on my 521 cid puller engine, to
save money. a few people before me ran them on their engines, engines that
were making substantial power with the CJ exhaust ports in the blue
thunders. the BT heads also have the ports raised. this might be a
problem for installation if the headers don't have the space to move.

in practice, the header pipe should always be bigger than the port exit,
but sometimes it is not possible. i think the performance lost would be
small on the smaller engines. but, one could modify the l&l headers to
fit.

cut off the flange, and open the flage holes up to CJ size. then reweld
the flange back onto the pipes using a length of pipe of larger diameter
either in cone shape or stepped down to the small L&L header primary pipe
size.

if this is done, i recommend on a under 500hp/490 cid engine making a port
plate that fits into the CJ exhaust port and raises the port floor a small
amount guiding the exhaust into the header pipes. this is done on the 351
C 4V heads very often.

if you are building a "big" engine, custom headers are a nice thing. the
l&l's could be used as a "template" for the pipe bends, or at least a guide
to follow to get close to a fit. i have custom headers on my 79 f350
puller. they don't fit as nice as the L&L's on my 77 f150 in some ways,
and on my puller i must pull the engine to insert headers or pull of
everything around the the front end. on the 77, i need only pull the one
shock bracket. smaller tubes do make things easier.

oh, the flanges can be bought for a CJ header from engine systems in
georgia for one place.

the mismatch of port, won't really create much more back pressure, the pipe
diameter and the valve/port have a larger effect on that IMHO. the
reversion is a problem though. that is why we like to have the pipe biger
than the port, for its anti-reversion characteristics.

if the port is larger, it creates odd, and "performance destructive" waves
and turbulance that cause breathing problems. but if the smaller tube is
stepped to a larger tube (modify headers as above) the reversion stays the
way we want it, and stepped headers MAY even perform better. in fact i
have a program to calculate the lengths and sizes of header
tubes/collectors for stepped headers.

I stand corrected; Blue Thunder. On under 500hp/490ci, it would seem that
some back-pressure would be developed with the larger exhaust port on the
head exiting into a smaller diameter opening?

George Miller


blue flame? do you mean blue thunder? us truck pullers started out with
the l&l headers. then moved to custom headers that fit. headers should be
bigger than the exhaust port. with the raised ports on the blue thunder
heads or the BB chevy ports on the "B" style blue thunder heads additional
mods are required.

i don't feel that the smaller headers would be much a problem really unless
you where building a 500+ hp engine or over 490 cubes, but that is IMHO.

the people i know are all running custom headers once they move to the
better heads. spending $2000 to $5000 for heads makes a few hundred for
headers seem like pocket change almost,

I'd like to know what exhaust headers people are using on the CJ, SVO
Aluminum and Blue Flame heads.

The standard aftermarket 460 headers don't match the larger exhaust ports
on these heads. I've talked to several of the manufacturers, including L&L,
and there are no plans to make them. Original SCJ/CJ exhaust manifolds are
rarer than the heads. My Hedman Headers are fine for the DOVE and PI heads
but left a lot to be desired with the CJs. Any info will be appreciated.

On my 76 F-250 4x4 with a 525 CJ I made my own fenderwhell headers I dont
belive any one makes headers for any apps for trucks... one option that I have
done in the past when i dont feel like making new headers is to have a flange
flame cut using the header gaskets and weld the new flange to the old headers
after cutting off the old flange.. ita a lot of work but it is sometimes the
only way and it works well.

Thanks to those who really had somthing to say, as for the rest of you

The 93 Ranger only has one belt. So it makes it hard to just simpily
take of the belt if I still want the engine to run. I had the steering
wheel replaced about a year ago. Would that affect the pump ?

Subject: RE: FTE Perf - Headers

my headers are from Ed Hennamen of Headers By Ed. they were custom for
the motor they originally were used on. (i run almost all used parts to
keep costs down.)
original motor was a 528 turning beyond 9000 at times.
they are real clost to optimum for my 521. quality good, but i do like
heavier flanges than even these. welds are decent and shape is ok. not a
top notch job, but i got them cheep used so...

his lengths and dia are vry close to everything i calculate, and even the
programs i have so i think he knows his stuff in that area. (2.125", about
31" long) i think it could have longer collectors, but that is a guess
more than anything. i feel most people run too short a collector anyway.

ps-if you spend alot on custom headers made for you, or made yourself, it
may be wise to jet coat them so they last. mine are VERY rusted!

Subject: FTE Perf - Exhaust Headers

I use the 3/4T/460 Hedmans in a full sized Bronco; fit fine with a ding in
one runner but the engine has to be pulled to remove them. People can say
what they want about cheap headers but I've ran them for over ten years in
all kinds of climates. Look kind of nasty now but they do the job.
The new flange on an existing set of headers sounds like the only way
to go. Maybe on the existing flange, grind out the original to match for
added stability and gradual reduction of exhaust flow?
