setting the timing?
I know the timing is supposed to be 4 degrees BTDC for a 79 L-48. since my motor was rebuilt before I purchased it and was built to 225hp it has a larger cam in it. I DO NOT HAVE ANY SPECS ON THE CAM THAT WAS INSTALLED.My question is where would you set the timing?? and at what rpm???

Back in the 60s, when we could not afford a timing light, we used to keep the distributor bolt finger tight, then keep advancing it until the engine rattled under load at low rpm...then we backed it off a notch and tightened the bolt. Your engine will know what the timing should be...given the gas in the tank and the atmospheric conditions.

My current timing paper has the complete setup procedure along with recommended specs for different applications. Just e-mail me for a copy.
