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??


any help will be greatly appreciated...thank you.
