It would depend on how hard ya want to turn it!?!?! We use the 010 4 bolt main blocks for our IMCA LM engine, approx 500 hp and it'll turn 74 to 7500 rpms all day long but that's as hard as I'd push it. I have another 010 2 bolt that has 5 seasons on it in a limited late model---425 hp and 7100 rpms or so. It get's freshened and checked over every year but no problems.

Thats right some dont have the pushrod hole in them.

They are lighter, i dont thnk you would want to go more than .30 over on the bore because of that.

Does anyone make a balance weight so I can use my old style flywheel with the one piece rear main seal crank?

The flywheel is a totally different bolt pattern. You can run an old style crank in a newer block with adapters. They you can run your same flywheel. We have a lightweight flywheel I would sell if you were interested that would fit a new style motor. Came from an 88 Vette.

I have a 350 that came out of a 95 chevy truck. Are these motors weaker and less powerful compared to the older 350's? If they are weaker, what makes them weak? I plan to put it in my bomber and put some camel back heads with an aluminum intake, does that sound alright? will it get me some more horses?

They are weaker simply because they are cast lighter.. meaning less iron which saves the factory money but also makes the block weaker.
