How Much Power?
I have a 350 that I spun a bearing in on the dyno. So I tore it all apart and was told that the block was ok but the crank should only be used as a paper weight. I decided to go with an Eagle internally balanced 383 kit with 5.7in rods and 10.4:1 cr. I have a set of Vortec 062 heads with roller rockers and roller hydraulic lifters set up to work with my cam which has 510 lift and 230 duration at .050. How much power do you think it will make

I have a performer RPM intake with a 650 Holley right now but I might swap the carb out for somethig bigger. I have block hugger headers and stock 69 side exhaust. I havent heard of an engine dyno anywhere around me but I do plan to put it on a wheel dyno once I get it back in the car.

Lord knows if it spun one on chassis dyno already ... that oughta be some incentive to find an engine dyno before you install another motor ... fill out your profile w/ approx geog location & maybe someone can point you to nearest one.
If I were spending $ on internal flattop 383 kit for a roller cam motor ... I'd choose 6" rods & pistons to match.

why would an engine dyno make a difference over a wheel dyno as far as stress on the engine goes. As far as I'm concerned a wheel dyno is better because it tells you how much power you make actually have at the wheels and not at the flywheel which could be 15-20% less. The reason it spun a bearing was because it was a tired motor that I planned on rebuilding but wanted to get a baseline first, the other bearings, that didnt spin, were pretty worn out (could see the copper)
