60 over with a 400 crank is around a 388. as far as power goes, it just depends on how you built it, 500 ft/lbs is very possible.

Re: 350 bored 60 over with a 400 crank

Switching from 76cc heads to 64cc is quite a jump. What type of pistons are you going to use? Increasing the bore and stroke also increases your compression ratio [img]/forums/images/graemlins/thinking.gif[/img]

Are you building a motor that will be driven daily?

Ok, I'll be the smartass.

A 400 crank won't fit in a 350. [img]/forums/images/graemlins/thumb.gif[/img]

That's why you remove .200" from the mains and clearance the block. [img]/forums/images/graemlins/thumb.gif[/img]

Also lets go ahead and get technical here, a 350 + .060" with a 3.75" stroke is actually 388.38658. [img]/forums/images/graemlins/rotfl.gif[/img]
