sm block Camaro header question...

[iluv69s]

the headers line up very well with the exhaust humps in the x-member. 6 to 8 inches seems like very short. I dont know if I have enough collector to cut them that short..?? I was now thinking I should bolt the body shell to the subframe prior to cutting and welding the flanges...just to make sure it fits and there are no clearance issues with the bolts, etc. I will do that soon as I need to testfit the body parts, glass, etc. before paint anyway.

thanks ..


for now I am going to just extend the headers with slip type 3" pipe and attach some mufflers so I can wake up this liitle mouse for the first time ever in 44 years!! hopefully this week!!

good idea.

thanks guys.....but does anyone know the whole scenario with the torque curve and the length of the collectors?? i remember reading about Smokey yunick or the Penske TA Camaro that they changed the header collector length to change/help the torque???

I'll put a few pics on this week when I get to working on the car again. thanks again.

The old school trick was to put a length of painted pipe behind the collector...and where the paint stopped burning off is where you cut the collector.

I don't know how accurate that was though?

I believe longer collector means more low end but if you are going to be corked up and running around the street it won't matter. Besides there is alot more tuning involved for optimum performance. You are building a street car correct?
