How many horse per cube?
I like to use the 1 Hp per cubic inch rule, for the average motor that is acheived with improved intake and exhaust, mild porting and a cam in the 220-230 degree range.
Wulfs motor has decent porting, raised compression and a big duration cam, (324* gross so 260ish net); With a proper sized slide carb and header (valve seat finish will factor a bit too) he'll be between 1.25 and 1.5 Hp per cube.
So 13 cubic inch x 1.25-1.5 = 16.25-19.5 HP
The higher # if he jets it right, Solid mid to top end power.
What kind of power are you expecting from this
