stock or ported intake manifold(LT1)
I am building a LT1 383 FI motor. Which manifold should I use? I thought I read on here the stock intake is good for 1000hp. Is there really a difference on a ported intake and especially with forced induction? I run a 52mm TB so the 58mm openings isn't an issue. The runners just look alittle bigger, nothing crazy.Just wondering everyones thoughts. Thanks.....John

Re: stock or ported intake manifold(LT1)
it needs to match the intake ports on the head... no bigger, no smaller.
A lot of people gasket-match the heads and intake for this reason. It's easier to make them match up perfectly.

I know people gasket match them but is there any advantage? I thought the stock manifold was as good as it gets in stock form. Does any body have any proof (dyno numbers) on stock vs. ported intake. Thanks....john
