The aluminum caps will help it a lot. Plus if you use aluminum rods it will help it even more. Whatever you can do to dampen the blow to the main webbing the better.

I have used a stock short filled block with program caps and steel rods with a stock 440 crank, and went 136mph in a 4005 lbs car. You do the math for horsepower. This will be the 4 year on the motor in 09, but it could also be the last?
There was also a little nitrous there to help me along....hehe!

They might last for a while under or at 700 hp. The main girdle, and other stuff will not keep them from splitting the cylinders. It seems this is 50% of the failures, the other is the main caps breaking. The after market stuff helps in this area, but nothing can be done about the cylinders...Im sorry filling the block doesn't help

Oh! I agree that they will not last forever but there is alot of guys who have made some big reliable power using a stock block. I estimate that I am making over 800 when I spray it. The day will come when the block has had enough.

there's a guy at our track who's been making horsepower with a comma for many years with a stock block- fill and girdle. scary, but he has had zero problems. the mega blocks have not been so lucky. i think if you take pains, use the good parts and the best machine work and assembly, a good stock block can endure a lot. and there's that hot rod build up. what was that, about 1400? yikes.

i've read about mega blocks having cap walk and bore thickness issues. i think it was the early blocks? there have been a couple of spectacular mega block failures in our area, but i think they were both the result of valve train failure. most engine failures i see are because of valve train failures, not block related, whether stock or aftermarket.

If you want it to live, I would say 600-650...

I am not a fan of "Girdles" and would never run one..but I have had more than one stock block with alum caps and rods, that made over 1,000hp on the spray. Actually never broken an alum capped block. Definitely not saying you won't break one, but I never have.

Thanks, I don't have aluminum rods, I guess I might be looking at that now though. I guess I should have asked before I bought my balanced rotating assembly.

Just use a 400 block and make the HP that you want and last.
I already bought the kit for a 440.

Thanks for the replies, I guess I might have to tone it down a bit for reliability, I wouldn't want to blow it up after teasing my chevy buddies
get blown not blownup.

See, this I don't understand, I thought the stresses would be worse with a blower. I have been thinking about a procharger set up.
