Its alive!!!!! Again!
Rock Flute now has a 90 hp heart that can rev to the moon.... after some tuning.
I tightened up the head bolts a bit, set the tappet clearance, adjusted the cam chain, swapped all the covers, and also found out that my cam tower bolts are pulling out! jeeeze!
Thankfully John has a valve cover that has cam tower hold downs installed. this was an old trick for monstrous cams of the early 70s that added bungs to the valve cover and used bolts to press down onto the cam towers. Few cams if any really need this because lift doesn't help these engines much. As long as the ramp on the cam isn't incredibly dramatic, the forces on the towers aren't really increased that much from an stock. The heavy duty valve springs do however add force. I think the threads on my cam tower bolt holes were stripped a bit already... Its not too bad, but I can't get the torque applied to a few.
A wee bit more work and Ill take it for a spin.
