Whats everyone's thoughts on B/500

I built a 451 using Mopar rods and a 440 crank, 400 Block. That thing ran great! Instant rev when you pop the throttle open. I like the short skirt piston. Looks like a (dare I say? ) small block Chevy unit. And we know how well those things rev! When comparing a 451 piston to a stock 440 piston, the 440 piston looks like a slug. Its 350 to 400 grams heavier. And at 6000 RPM, THE piston is changing direction 200 times a second! No wonder it seems like there's a heavy flywheel hooked onto it when you rev it. Go with the 451 or 512. A budget build requires turning down the 440 mains, and new pistons. You can use the LY rods with a 1.32 C Height piston. I'll never build another 440 if I can do a 451. Plus it's 40 lbs lighter! I put a lot of miles on mine. Plus about 100 runs down the 1/4 mile in a 69 RR, and it always ran great !
