So a little back ground first: My dad had this engine rebuilt in 2000. The engine builder has built many big and small block chevy's for my dad over the years but I think this is the only Mopar. It is a stock 1970 383 4 speed, .010 overbore, stock crank, rods, stock CR pistons, restoration cam, Holley 600 Vac secondaries stock exhaust. We received the car last month out of dry storage. Car started up fine but would not pull itself into the garage....
So first we changed oil and filter, added new plugs, wires, coil, Mopar electronic ignition upgrade, and voltage regulator.
After that the car would pull itself around the yard much better, but it still revs lazy up to about 3500 (almost feels like its missing with a vibration) 3500-6000 is cleaner. Out on the road it runs like a worn out 318 2 barrel. Wont even squeak the tires without revving it way up (4500 or more)
But, she starts right up, the plugs look real good (brownish white) there is no smoke or any weird noises, The car doesn't overheat at all, total run time on engine since rebuild is about 6 hours maybe 20 miles....
So we had to blow the car apart to get it to paint before Daytona turkey rod run, but I want to have a plan for when the car returns to sort this out. My gut tells me its timing related. I plan to verify TDC and check the valve positions to ensure cam is installed correctly, but after that anybody have any other ideas? Thanks in advance.
