Folks, first of all thanks for all your help in answering my ongoing questions on this.
First the basics. Motor is a DZ bored 10 over, stock intake, Edelbrock 750 CFM carb chokeless, solid lifter stock cam, 480 distributor with points ignition, taylor wires and Delco 43s plugs. I am running a 50/50 mix of 106 octance Cam 2 and 94 octane pump.
Engine was running SY1, but ran like crap so switched everything to stock except carb, since Holleys are more tempermental than my wife.
Here's the problem: I timed the engine at 8 degrees (rotor pointing at 1 on Cap), vacuum advance plugged, gapped the points properly started her up and set the idle at 800-850. The timing on my dial back red 15 degrees total at idle. The engine runs cool, but sounds a little lopey (on account of the cam). When she starts she would cough twice before she smoothed out but I figured that was the compression.
Backed her into the driveway no problem. Tried to drive back in and all hell breaks loose. Under load she coughs spputters backfires and stalls. Blew a serious shot out of the carb and back towards the windo from the cowl hood (Air cleaner was off).
I pulled the distributor and checked everything again and it seems right. Checked for vacuum leaks and can't find any. One buddy says timing could be off a tooth and your adjustment range can't compensate. Another says valves could be off but I set them based on technical info I got here and checked and rechecked the valves.
I am ready to sell the damn thing and drive my low compression 72 olds which starts up and runs like a champ.
Any idea before I throw a cover over this car and forget about it? I am learning to hate this car. [img]graemlins/angry.gif[/img]
