K guys here's the deal. I have a 1987 iroc with a 2000 LS1, ported 6.0 liter heads, comp cams 232/238 .562/.567, LS1 motorsports T76 turbo kit at 10psi(modified to fit of course lol). I am stuck on a manifold choice. I can get a Lingenfelter aluminum intake manifold for the same price as an LS6 manifold right now. BUT, not sure which one would be most beneficiary to my setup. The LS6 is an awesome intake, don't know much about the Lingenfelter. So opinions and advice would be appreciated. I know the Lingenfelter one will be easier to port match etc. Which one would work best??? Oh, and the new shortblock for it will be seeing around 16-18psi (408, 6.0 iron block, forged internals)
