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.

Thanks Alan. Any AIX guys want to buy some ZR1 11" wheels, Black? I'll trade for 2 ( 91/2")
don't have scale to weight now, would 400engine hp be safe for starters?
does AI approve of a 383ci stroked. If its within the hp requirements of 9.5:1 it should be fine?
Do window clips have any sizes or material?
Do we have to install quick lock steering wheel?

There is a good market for 17x11's - post them for sale/trade in the classified. The 17x9.5 wheels of choice are 01-04 Z06 fronts - they are the right size and offset, reasonably light, and can be picked up for around $500 for a set of 4 - watch the Corvetteforum classifieds.

There are no rules in AI regarding motor mods, except: no blowers, no NO, no dry sump, no wrong brands. Avoid overbuilding the motor - it is better to be a little low on HP, and put your $ and effort towards adding lightness, and fine tuning the suspension/aero. If you haven't got money invested yet in the 383, I'd stick with stock bore, put a Canton RR pan on it, and long tube headers. Your iron block will be a disadvantage, with about 60# more on the front vs an LS motor.

Window clips are optional - if you use Lexan in the front (3/16" thick) it must have at least one interior brace.

Removable steering wheel is not required, but pretty much a practical necessity with a proper cage and seat.

Do I still need the current spacers to make these wheels work? Thanks for all your help. Im closer than I thought.

A lot of 4th gen AI/CMC2 cars are running the Z06 fronts with my 1/2" spacers on all 4 corners. The spacers aren't absolutely necessary, but they reduce roll and give more clearance for brake ducts, and eliminate a lot of pounding of the inner fender wells.

I can't say how they fit on a third gen, there should be some threads here that should help.
