eek. well for the heads im willing to fork out a few grand, and aluminum, so im not limited too much as for the cost. ill have to run that cam or one similar and see how i like it first. okay i want to build the 468 mentioned in chevy hi performance. the ''ROAST RAT'' check that out and let me know and what you would recomend. i was planning on running a few different parts, like the carb and different exhaust. but thats what im going for.
