302 HP estimate

I'm curious what you guys think I may be making for power, my newest toy happens to have a 90' 302 that was punched .60 over, making it a 310 right? Well on top of that I'm adding a procharger P1SC, 42lb injectors, 255 fuel pump, trick flow street race heads, BBK headers with full exhaust, and a custom burned diablo chip. Any clue what kind of power this motor may be making? How much would I gain by stroking it out to a 331?

Thanks guys! Hopefully I have it done before next weekend

I'm just sitting here at work thinking about it.

Either a 303, or a stocker.... If it's stock it won't be for long

It doesn't matter if you are 302 or 347, the peak horsepower stays the same, while you gain much more low end torque. A dyno was posted here showing that from a respected magazine test.

It should make about 400hp at the crank.. how much of that gets to the ground depends upon tranny, gearing, and tire size.

You might want to look into beefing up the block up with at least a main girdle. I have learned from this website and others that stock 302 blocks can only withstand so much horsepower without breaking or splitting. I think with your setup you might be looking at 400-450hp like conanski said. But if you go 331 stroker and custom camshaft...way more.
