Big block swap headers

[Paulmersheim]

I have a 72 grade with a 429 swap. For starters does the Grande have the same engine bay as a mach 1? And what headers will work with the ford 385 block in my car?

All 71-73 engine bays are the same.

I used Ford Powertrain Applications mid length header. Only slight massaging of one tube at the steering box needed. Very good quality header.

Cool. Thanks for the answer. Where did you pick those headers up at and about what was the cost?

+1 on the FPA headers.

The hookers I had, which I did not use, had very large collectors & the front two tubes on both sides ran under the cross member. Every used set on or off a car have road rash on them.......

I used stock exhaust manifolds from a mid eighties truck on mine.

Thanks, Jay

Engine bay the same but you need the bigger 429 springs to support the extra engine weight.
