[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

Yeah you're going to have to forget about the 383. The problem is there's also a torque to weight ratio rule; with a stroker motor it's very hard to tune down the torque numbers to stay legal. i'm not sure if you have a block already or what but the two ways I would go with it are; aluminum headed long block from Blueprint engines or GMPP, or if you have a block get a decent rotating assembly and spend the money on longetivity I.E. ARP bolts and MLS gaskets if you can swing it. Good oil control is a must!!!! Road race poil pan, oil cooler and an accusump and you'll have one less thing to worry about.

Don't go crazy on the motor, just get something built that will hold up, get it in the car, found out what kind of power it makes and build the car around that. 320 is an easy number to shoot for with a 350. From there you know what weight you have to shoot for and that will dictate everything else down the line. Like you may not have to spend money on lexan windows because you actually need the weight that sort of thing.
