I have one that made 34.7hp on my dyno. (A real good AKRA legal clone shows 12.5ish here). Its a True Honda block, bored .080..Hemi pred piston, 28.5 27mm valves, heavily ported, milled to 15cc, valve reliefs cut in the piston, custom ground 360 lift, 260@.050 cam,Arc Rod, Arc flywheel, Bored 390 carb, on meth. Oh yea, it made 28hp NA, and the 34.7 was with a shot of Nitrous.:thumbsup:
