You will definitely need to use something other than the stock intake to make that power. Again, the LT1 intake is a good design but you will have to resolve the reverse flow cooling issues to adapt it to L98 duty. Then, I would certainly have it port matched to the heads to ensure the transition is correct.

GM also makes an intake that looks like an LT1 or TPIS Mini Ram. It's called the Ram Jet (part # 12489371)...comes on the Ram Jet 350 crate engine. You would need the throttle body for this intake also as it uses a single blade version (like the LS1 or Ford) verses the 2 blade deal on the L98. I don't know the price and you don't see them everywhere, but that would be another option for you in the intake department that should make the power he wants.

Speaking of throttle bodies, if you go with either the LT1 or the TPIS Mini Ram, plan on getting a 52mm (2 blade) version from BBK, Edelbrock or somebody.

The stock block will handle that power with no problems...assuming it's in good shape. You're only talking about 375-400rwhp tranny depending. No need for anything fancy i.e. 4 bolt mains and stuff.


My advice is still to slap the carb'd setup on that bitch....your talking less money, way less work and probably more pwer for your time/dollar.
