I am looking at building a 393 stroker motor. I am wanting to put a supercharger on it later on. Any suggestions on what to look at when building the motor?
I currently have a 74 351 block, Trick flow Street/Strip aluminum heads that are ported/polished with 2.02 intake and 1.60 exhaust valves. No intake yet or carb. I am wanting around 450 before supercharger if possible. Any suggestions??? Thanks.

The best advice I can give is to put a forged bottom end in it and keep compression moderate, say 8.5:1. Make sure you use a real good set of rings and bearings also.

You don't want your static compression too low or you'll not have any power on the lower RPM range even with a blower.

Thanks, I will look at it then. I am currently looking at a set of Mahle 4.030 302 pistons for the stroker kit that are forged. The crank is a nodular steel crank and I have a set of I beam 351 rods out of the 351w block that I am using. What is the best way to figure the compression ratio? The heads that I am using are Trick Flow Streep/Strip aluminum heads with 2.02/1.60 valves and combustion chamber is 64cc. Any ideas?

Here's a calculator to help you out. It looks like you're going to need a seriously dished piston to get the CR down where you need it.
