aight i got my motor back together and she has a peppy top end thats for sure.....

350 bored 60 over KB 120 pistons about 9.7 to 1 comp
my heads are 441s and were 76cc but we resurfaced and cut um down I figure they are in the 70cc or maybe 64cc range.....
the block was decked 30 over and the head gask is that really common Mr. gasket that everyone uses.....
the cam is a comp xe 268 h 10
edelbrock torker 2 intake (I know I know)
holley 600 cfm carb and the cam is installed straight up........

she spin up to 5 grand like its nuthin but she has a bit of a low end bog....I need to play with my timeing some more and get my carb tuned...... but once that is all done what kinda HP numbers do u think shell kick out......

You kind of have a in between. The small carb is holding your HP down, but your intake is hurting your torque.

Keep in mind that digital "dynos" tend to be a little optimistic.

Your real measure of HP will be your MPH.

When are you going to run this thing? I'm VERY interested in what this thing will run.

Good luck.
