Need compression ratio, is bottom end stock? Block decked? And did you use a steel shim gasket head gasket or stock head gasket.

Comp Ratio should be around 9.75...........Bottom End is Stock, Block has not been decked, and used a stock head gasket......Thanx Again......... :thumbs:

I didn't have a flow file for your heads, so I plugged in the numbers from a set of 64cc 882 heads, and came up with 409 torque at 3500 rpm and 340 hp at 5000 rpm.
You could be getting a lot more with a bigger cam, an XE262 would have given you 362hp at 5000 and 408 torque at 3500, peak power.
The XE268 would give you 375 at 5500 and 405 at 4000 rpm.
This is only an estimate, since there are too many other variables to consider, but it gets you in the ballpark.

Thanx Smokehouse........I kinda figured that cam was a little small for my new set up, but then 340HP and 400+ ft/lbs sounds GREAT rite now.......Thanx again to you and Motorhead. :cheers: :cheers: :cheers:
