LT1 Optispark/timing issues

[quikws6]

This is a reply that is straight from a well known engine builder. "You need to degree the camshaft when you install it to ensure that it is ground properly. We don't perform 100% in house QC on cams for fun - they need to be checked if the customer doesn't want to degree them, and wants the camshaft installed on a specific centerline...(dot to dot,advanced,retarded)... That isn't to say it won't run if the camshaft/timingset/etc. tolerances stack up and it isn't where you think it is, but it is worth consideration." Plenty of info out there on the procedure.



Also, If you haven't seen the ls1 computer conversion people are doing over on ls1tech you may want to look into it. Hope that helps, good luck!
