i have a 77 f250 with a stock 460. i took it to get my carb rebuilt and the mechanic said my manifold is leaking a little bit of air, so i figure if i am going to have to take my manifold off anyways, i might aswell replace it with something that will get me a bit more preformance.
my questions are:
does anyone make a manifold that is a direct replacement for the stock but that flows better for more power, it needs to accept the stock 4bbl carb and have a provision for the original "chole stoke". ????
or.....
should i find go to a junk yard and find a manifold just like mine, then take it and have it ported and painted so it looks nice then put that on instead??
Before going out and spending money on a new manifold that you may not need to spend, why not remove your manifold, have it cleaned, and re-install it with a new set of gaskets? I'm having a really hard time trying to understand how your cast iron factory intake could be wore out enough to merit replacement. I've never heard of a factory cast manifold warping, and there are no moving parts to wear out, so it makes sense to me that it's probably just your gaskets that are at fault. Save your dollars for a new carb, or a new ignition system.

what i am leaning towards is findind a direct stock replacement from a junk yard and having it ported and polished and then having it powdercoated to the orginal ford blue then installing it, my old manifold may not need to be replaced but this is my daily driver and if i have to take my manifold off to change the rubber i might as well get some preformance out of it anyways...
besides i just intalled a new msd ignition and my carb was just rebuilt and tuned..,thanx
