Here's a small block suggestion. Get a 95'-97' LT1 intake, have the intake modified(lt1intake.com) so that you can use a regular HEI distributor. Order a FAST computer and harness because it allows better tuning of the system. That should make for an excellent combo. Good luck with it.
Also, Vortech makes a blow-thru setup for carb'd applications, you could save some $ there.
