Equation for measuring internal displacement of an engine is:
Bore Raduis ^2 * 3.14 (Pi) * Stroke * # of cylinders = Internal Displacement

soo a 351W bored 0.30 over is

2.015 ^2 * 3.14 * 3.5 * 8 = 356.974982 CI

and so on

a 302 bored 0.30 over

2.015 ^2 * 3.14 * 3.0 * 8 = 305.978556 CI

Awesome info Jurg. I never actually knew the formula, but had a relative idea of what was going on and would guesstimate.

The internet may be a wonderful thing, but sometimes you just can't beat the desktop technical reference manual, LOL-

Ouch...that hurts Don. But I make up for my job by working on my rigs. BTW...I know what real work was like, and it sucked. I don't mind getting paid what I do in the A/C...might get boring some times, but when that paycheck comes and I buy parts...everything else just goes away.
