[IROC383]

Hey guys.
After last weekends autox, looks like I don't have much time left on current motor.
In a perfect world. what is the best combo motor application for RR. Whats the typical RPM range I need to build for? I am AIX. By accident I have 3rd gen with T56, C5, brakes, ZR1 11" wheels. So lets build something that will kick some a$$ but have good longevity. Using Iron roller block. Is the Moroso RR oil pan good? I have L31 heads, .512 lift crane hydraulic roller cam, vortec intake and 800DP Holley, 15/8 headers. SRP inverted dome piston and eagle rods. My question is: 383 or 350 ci. Open for suggestions. Going to build this over the Thanksgiving holiday Thanks Jarrod

Thanks for all the kind words and advise. Sidney, you've made good sense. I have found general comp rules but not any details on classes, hp, wheels sizes, weight etc. If you could share a link to the nasa ccr i would love to follow your lead. Engine hp is 320 to the ground. I'll work on that first. Anybody in the Southeast that i could hook up with?

All of NASA's rules are here: http://www.nasaproracing.com/rules

top one is the CCR - read the safety, drivers gear and rules of the road sections first.

A little further down is AI, there are some rules there that will override the CCR. If an item is not mentioned in the AI rules, it is governed by the CCR.

At 320rwhp, you are good for 3040# minimum, in impound after a race, with you, your gear, and remaining fuel. Those are great numbers for a 3rd gen. I'd build the motor for reliability, focus on getting seat time and licensed, then build the car for AI. As stated above, building a competitive AIX car is not for the light of wallet.
