since when are we talking about pushrods?? You're going to have a failure in the bottom end....like as in the piston rods or possibly the piston heads....
How do you expect to build a turbo Impala and keep it runnin w/ 400hp or whatever if you didn't even know that the bottom end is going to be weak? I was never talking about pushrods.....those don't matter near as much as the PISTON RODS and the PISTON HEADS. That's where you're going to have a failure.....
This site is Integra specific, but it has good info. You should really take some time out to read it. It will help, trust me.
