My brother is rebuilding his 351W in a 69 mach1.
Engine is out and he wants to install headers when it goes back in.
We are wondering what the best brand header is for the car with a 4 speed.
Anyone out there that has installed some? we are interested in hearing if any fit good without much modifications?
Just info on different manufacturers and how they worked for you would be appreciated.
I talked to someone about this a couple weeks ago at a cruise-in...he said the only set of headers he could find that would fit in his 69 351w w/4 spd were the Hooker Engine Swap headers...bad news is that they are $450. He said that the Z bar got in the way of many of the other headers. Any set of shorty headers would work as well I would suppose.
I have Hooker Comps on mine. Fit was fantastic, except where the driver's side goes past the scatter shield lip. You wouldn't have this problem if using a stock bell housing. I'm using a hydraulic clutch, though, so I had no clutch linkage problems.
One huge advantage of the Hooker Comps is that you don't need the PIA lowering bracket for power steering.

If you are not worried about price, hands down the best fitting header is the FPA headers. I have ceramic coated hooker comps and had very few fitment problems. AFAIK, neither require the power steering drop bracket.
What are the performance goals? The Hipo manifolds should (??) fit the 351 and will take less modification than long tubes. Good compromise between stock log style units and tubular. If you want max power, though, you can't beat long tubes and the '69 body has room. I tried SuperComps in my '65 and even the muffler shop could get 'em in. The repop Hipos fit just fine. Just a thought.
