Weekend project

Looky what I get to do this weekend
Motor is done and ready to drop in. I cant wait to see how the horsepower gain is going to turn those 35s now. I am figuring it will probably double my horsepower since the stock 302 in a 1981 mustang gt only pushed 125hp this motor should double that. what do you think here are the specs 1970 351w with edelborck performer cam and intake with holley 4 barrel and head froms a 1970 fairlane. bored 30 over.

Is that even doable? Enquiring Norm's want to know. I'd figure the jounal sizes would be totally different Since the Motor is a small block and the crank is out of a big block. That and would it even line up if you got it remachined?

Re: Weekend project

Just as a rough calculation here, the bore is .030 over. So it stands to reason that you are taking each cylinder of a 351 cubic inch motor and expanding by .030. I just take the .030 and multiply by 351 and that is apx. 11 more cubes, so 362 cubic inches. The math might not be perfect since we are actually talking about expanding the circumference/volume of a tube basically...expanding the bore.

Well, now I got to go see if my shortcut math is correct, or if you really need to take the new bore measurement and apply it in the formula for calculating volume of a cylinder x 8. [img]images/graemlins/crazy.gif[/img]
