Try a short stroke and aluminum rods!

Thank you for your input, I agree with your advice. However I'm more looking to gain statistical data over a critique of my current build. Without getting into a long winded explanation of my build, I will just say that its NOT built with the intention of being a dedicated drag/race car. The goal was literally to build a 500ci Cast Iron Pontiac, Fuel injected, with 15psi boost. It will be more of a street driven daily driver with an occasional run down the quarter mile. It will be set up more for twistys than drag.

I already posses my my components... so that approach although great advice would not be in line with the goal of the build.

Do you have any build specs of your build? Specifically with weights of components? It would be interesting to see what type of forces your block is containing vs others.

Thank you both for your input.

Not my build I wouldn’t do a boosted factory block for drag racing. I just threw it out there what I thought would help a combo like that to live at least a little while. I just re-read what you post about 15 lbs of boost and 500 inches..........lots of luck but I don't think i can help you with that combo and have me sleep good at night!
