Well, I took
your advise and put them in today. Quite a chore - had to release the motor
mounts, pick the engine/trans up about two inches to get them in. Between that
and rerouting starter wires, etc., it's all day job.
C
I would recommend the smaller headers for
day to day use. You get a broader torque curve that, in most cases, makes the
car stronger all around.

Thanks
very much for the help. I've got one more question for you about the 2" vs 1
and 3/4. My engine is a 402 bored to 414ci. The heads are Edelbrock Performer
RPM. Comp Cam Xtreme Energy with 552/555 lift and 230/236 duration @ 50. Lobe
sep is 110. Domed pistons milled to give 9:7 to 1. Stick shift Muncie,
Performer RPM intake with a matching carb. Would you still go 1 and 3/4 or
would the 2" produce better results overall?
I hate
to bug you but, since I have both sets of headers, I'm keen for input on what
to do. I've got to make a decision Saturday. The car is nice but I drive it
alot. I also take it to the strip monthly and thrash it pretty good. I just
don't know which ones will give the best results.

You can get the supercomps
in from underneath if you remove the oil filter and take the bolt out of the
motor mounts. Then you have to lift the motor up several inches with a
cherry picker. If you can get hold of the motor low enough you can do it
with the hood on. I installed the headers with the motor out but I have had
to remove them a time or two. I have the 2” ceramic coated version and by
laying a towel on the frame and control arm bolts I have been able to
install them more than once without scratching them.
As far as your question
about header size; I would use the 1 ¾” setup for the street, even with a
mild 454. If the car is to live at the drag strip, as mine does, I would,
and did use the 2”. Again, that depends on your cubic inches. The bigger the
motor, the bigger the pipe.

Yeah,
it's looking that way for me too. BTW, what displacement are you running
with those Supercomps? A couple of buddies of mine are telling me that 2"
headers are way too big - should be 1 and 3/4. Since I have a set of each,
I'm really wondering which one's to go with.

I installed a set of Hooker Header
Supercomp headers, and the only way to get them in on the drivers side was
to loosen motor mounts and lift the motor up about 2 inches and slide them
from the bottom up into the engine compartment.
