alright guys here is what im building. i have a late 60's model mexican 302 block stroked to a 331. with all probe forged internals, deep dish 20cc pistons, which should make my compression around 8.2-1, an e303 cam, gt-40 port and polished heads with upgraded vaulves, rockers, and springs, ported upper and lower intakes, 42lb injectors and 42lb maf. stock throttle body, and a turbonetics 67mm turbo. everyone keeps telling me im probably going to split my block. what is the safest way to go with this set up without buying a different block. i only plan to run the car to a 6k redline. and i keep seeing these turbo set ups on stock 302's runnin about 10-12lbs of boost. would my car hold up to around the same boost settings or what because i dont want to get my project going a split my block.

I have come across alot of threads discussing the mexican blocks. I have read about these motors running up 20lbs of boost don't know if it was B.S. or not bu they say 600hp no problem. Try these links out, I'm sure you will find them interesting and they should get you where you want.

As long as everything is assembled properly...your likely going to be just fine. With a 331 and that h/c/i setup...your likely looking at close to 600rwhp with 12lbs of boost. I'd think if you keep the RPM below 6k rpm and don't get crazy with the boost you'll be alright.
