Here's what you need. Please start here. I bet you have extremely low cylinder pressure with that fairly large cam. I think you may have a fuel delivery problem also.
I don't see how your pistons can be that far in the hole either? KB 107 has a 1.675 comp ht. Even at full deck height of 9.599 , 6.123 rod, 3.58" (1.79") = 9.588" which is .011" in the hole. Either your block is very tall or your rods have been shortened by excessive resizing or you have a messed up stroke on your crank. Fix your quench.
Eddy 600's suck for power but your engine should be stronger than what it is. I agree that you should have at least 400 crank hp--probably more like 425-440 hp with that cam.
You don't need a 750, in fact a Holley 650 HP will kick *** on this combo. Your exhaust may be hurting a little but I doubt changing it would make a large difference.
I agree 3.23's aren't ideal for your combo but it should still mile an hour better than that. If you are unwilling to change gears and converter then I really think you should step way way down on your cam. J.Rob
