Loss of power
Ok guys, need some more help. I addressed the water pump noise by replacing the water pump. To diagnose the H20 pump I took off all of the belts and started the engine. After replacing the pump, I put all of the accessories back on and started the engine. The car was idling very fast so I checked timing which showed it was advanced at 30* initial timing (engine is a 408 sbc, solid roller cam, rpm air gap, Dart pro 1 heads, Petronix distribuor, MSD Ignition). Before I disassembled the front end of the engine my car was timed at 13* initial timing. After retiming back to around 10-11* my car has lack of power. Before I could break the wheels free in 2nd gear but now I can't even get them to spin. The car revs up in 1st gear goin down the road but it's not gaining much speed (like before). I checked the timing tab to make sure it wasn't loose and it is tight. Not sure what else to check. Need some help.
