The Ford Barn

i know the performance differences are great....but im going with a custom downdraft intake manifold and was curious if the dimensions between the two exhaust manifolds have much of a difference?

the intake manifold i have is for a stock exhaust manifold, but i was hoping it will still clear if i upgrade it to a cast iron one from snyders.?

Not sure but you might want to post this on the HAMB, they have a "banger" group over there. There is also someone on the A swap section on the Barn who manufactures custom intakes and exhausts. Hope this helps

yes it will still work fine. You just can not use the original updraft intake with the aftermarket castiron exhaust manifold

One thing to consider is that the cast iron manifold acts like a big heat-sink and will put more heat into the passenger compartment. I've run both and like the tube headers better, partly for that reason.

If you use Reds headers a quick finish is a Speedway glasspack that has the 2.5" collector plate ready to bolt up.
