Disturbed Distributor

[jparrishable]

91 Sonoma 4.3. Distributor was left unmarked then pulled and crankshaft had been turned prior to re-install. Under hood info reads Set timing to 0 BTC. So, how do you find BTC? What procedure do you follow to re-install this disturbed distrib?

Think you mean TDC (Top Dead center).

This should help you get your timing back in order. http://www.truckmodcentral.com/forums/f63/timing-gm-5-0-5-7-4-3-vortec-6014/
