Timing Problem - The 1947 - Present Chevrolet & GMC Truck Message Board Network

raychevy · 04-14-2002, 07:42 PM

I posted this in the Engine board, and I dont think anyone knew for sure. This I think is a common 350 question. I hope someone can help me. I have a 77' Chevy c-10 350/350 turbo with 4 barrell. I had the timing checked and it was at 4 degrees. The engine sounds like it was running 4 to 500 rpm. It will slowly take off if the brake is released. What should the timing be set too ? And if mine is wrong could this make extra valve noise, and rob it of power ? Its strong now, but I think it isnt getting its total potential. I have a dwell and rpm test machine, but I cannot find the wire to clip the end on to make it work. The truck has electronic ignition. Anyone know what color wire im looking for ? Thanks in advance

The timing depends on if it's a auto, or straight drive? If it's auto it should be around 6 to 8 degree's top dead center, with the vacuum unpluged and something plugging the vacuum leak. If it's a straight drive 5 or 6 should be ok. Hope this helps.

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
