Cam Timing question

[Boat1]

Keep in mind that backing the timing down with a correct fuel curve raises the exhaust gas temperatures. I would set the timing at 34 or 36 total, your break-in is controlled by the throttle hand not the timing. If possible you really should dyno one engine and two carburetors, that will identify your fuel curve, your total timing, and tell you where peak torque is. Knowing peak torque you can try and prop 600-800 rpm above that for WOT rpm. Like it or not you have a custom engine, it requires custom tuning for maximum output. Good Luck.

Thanks for that tip Boat1.

One final question. I'm looking at the cam degree bushings... what keeps them from falling out??

 

[WETTE VETTE]

The retainer plate on the front and the cam on the back.

I didn't see a retainer in the kits at Summit. Thanks for the reply.

The retainer plate is a plate that is designed with bend up lock tabs to keep the camshaft sproket bolts from coming loose, that is it's intended function. It will, by default, keep the degree bushings in place also.

Gotcha. Found them now.
Thanks!
