44 arc engine? I've installed 2 of these cams in Inteks, cam is made to use stock
timing marks.I always degree my installed cams so I know the actual valve timing events.
The cheetah cam is a good cam if installed right&will run 7500-7800rpm all day long.Did you change valve springs?

Thanks for the reply PJG56, Up graded springs and a single 38 mikuni w/480 main. (plugs burning good). I used stock timing marks also, but have not used a degree wheel. i would think that would get me close, Do you know good literature to use degree wheel? Also touch the key and this engine fires right up.

This is for ignition timing,has nothing to do with valve timing events.How did you adapt 38 mikuni to intake manifold?
