Thanks for the replies. Hei distributor,stock 402 engine. What I did was remove some pulleys (to paint),took smog pump/diverter valve off and hoses.Blocked off the check valves (until I figure out what I'm going to do). Had the carb rebuilt (shop) and reinstalled everything. I've checked the timing which is between 10-12 degrees. Adjusted the carb a little richer (thought maybe to lean). All vacuum hoses are connected. Car ran fine before this so I am lost. Just sputters/pops on drivers side bank when I start to get into the pedal.

When putting the pulley back onto crankshaft and tightening it,the crank moved a few times. Will that offset my timing in the car? It idles great and revs up fine in park. But when I step into it it sputters and pops in exhaust system. Any feedback would help. Thanks!

Got it. Great idea Thanks!

I need to block the check valves off from the exhaust manifolds until I figure out what I'm going to do. Any suggestions for a temp fix?

Stay as stock as possible. GM did great job making the car look that way.

Where is that relay located for the high setting for the blower motor? Thanks!
