350 bored to 355 isnt worth mentioning, your only looking at a maybe 5-7 HP differance in hp

A 377 (400 with a 350 crank) would probably be the easiest way to make 450hp. In order to make that much hp, you're going to have to have an engine capable of running a lot of rpms which would make me shy way away from the 365. That's way too much stroke for a little tiny piston. The 350 and 327 will have to run 6500-7000 to make that hp. You could probably get away with 6000 with the 377 and it's a whole lot easier and cheaper to build a 6000 rpm engine than a 7000 rpm engine.

nah just a toy to drive every now and then

he way these deep pocket (DADDY"S)highschool kids are now days if you don't have at least 375hp its all tail lights

thx guys for the help

I'd say use the 355 and get a 383 rotating assembly. a beefy cam and good heads will def. yield 450 hp and serious toque
