-Crower Corvette LT-1 grind cam/roller rockers of course/rods
-Edelbrock Performer EPS Intake Manifolds
-600 or 800 cfm Thunder series Edelborck carbs
-You can mill the heads .010 to boost compression .5 or go with new performance heads too.
Without heads expect 20% or 60 HP gains with heads 80-100 HP
Speed increase 3-5 MPH

Re: lookin for bolt on power !
Here are some general guidelines...
It cost $1000 for each additional 1 MPH.
If you look at an internal compustion engine as a huge air pump, then you want to increase airflow both into and out of the engine. A low restriction flame arrestor and after-market manifolds will help with that. Once you get more air into the engine, you need to add more gas. This means a bigger carb or a new ECM program.
The BEST bang for your buck is to add a supercharger. I have a Whipple, and I love it!
Good luck!
