i just started up a rebuilt 350 with vortec heads. as soon as i got it running, i reved it to 2000 reguardless of the timing. i tried to put it at the best timing to let it run. the exhaust was pumping out a slight white smoke that didnt smell like coolant and i didnt see any bubbles in radiator. the temp rose to about 195 and started to climb, which i assumed that the bad timing was the reason of the hot temp. the exhaust not sounded off to. tomorrow im going to start it back up, let it idle, and set the timing. what do yall think?
