Re: big block chevy headers?
after a few minutes of searching, and a few dozen more in autocad, I ploted all of the ports and heres what the port differences are.
clint
the LS has a 4.400 ceter to center on the ports... the SB fords has the closest at 4.380... the BBC had a massive 4.840" when I made an overlay, its damn close... probally close enough that you could make a LS head bolt pattern w/SBF port spacing and call it a day... well depending on how the headers fit the body..?
