I took the engine almost completely apart and checked clearances, bolt torques and basically checked it all over. Everything checked out good.


I decided to degree the cam and double check all the specs. I fabricated a piston stop out of aluminum angle and a lifter extension for the dial indicator out of an old brake line and washer.





Here's the specs...


This is what I came up with:
Int open - 1* BTDC = 2* retarded
Int close - 41* ABDC = ON SPEC

Exh open - 54* BBDC = 2* retarded
Exh close - 2* BTDC = ON SPEC

Lobe centerline - Int 109* ATDC = ON SPEC
Lobe centerline - Exh 120* BTDC = 1* advanced

I decided with some trusted advice that it was close enough for my purposes. Though the crank sprocket has provisions for 4 degree advance or retard. I may do some more research to see if advancing the cam will be a benefit.
