I am running a 306 right now and decided to go with a 331. I have purchased some H beam Scat rods and a Scat Forged crank. I plan on getting some -14 cc dished Probe Pistons. I have picked up a Trick Flow stage 1 cam to replace my E303 I have now. I plan on reusing my AFR 165 heads and 1.7 roller rockers. The only way I may step up to AFR 185's is if I sell my existing motor as a long block than a short block. I hope to have 475-500 rwhp when it is all done.
I am tempted to run a stock roller block since I can pick one up that is already bored and machined for $100. I hear horror stories about blocks cracking when you approach 500 hp at the crank. I hope to be well beyond that mark. I don't plan on spinning the car past 6000-6500 rpm. Is there much to worry about? Do I really need an aftermarket block for a street car? Thanks for the help.
