    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.

    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 /forums/images/graemlins/thinking.gif

    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. /forums/images/graemlins/thumb.gif

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

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