When the first one comes off the dyno.

Which is when?

Probably two weeks. Only pieces we are waiting on are my carburetors and stud girdles. I bit off a little more than I could chew doing three of these I think. lol

The only parts I reused from my old motors are the blocks and the ignitions. My UPS man is just starting to speak to me again after carrying 3 crankshafts, 3 sets of heads, and 3 of everything else.

DING DING!

Should make 1.25 to 1.32 HP per cubic inch so long as the compression isn't 10:1+ and the cam isn't too narrow of a LSA.

How much difference in hp between the three motors?????????

I call a 2% spread, 14hp.

Your heads and valve train are the same as mine with bob's cam 112 center line, 714hp @ 6,000rpm, mine is a 555ci, with cnc cambers.They will sound good with dry exhaust.

683 @ 5800 rpm :-)

Updates?
