I'm trying to get my GMC pickup on the road after being stored for 9 years. It's got a SBC 283 that a buddy helped me install in 1982. After reading lots of info, I decided to put Marvel Mystery Oil in the plug holes, remove valve covers and pour Marvel on the rockers, change the oil, pull the distributor and spin the oil pump via the distributor access and then rotate the engine by hand to get the motor to turn and check that it's not locked up and that all rockers/valves are moving. I realize this is probably overkill, but want the best chances of the motor running well for awhile, since I can't afford a new motor right now.

That said, I realized I have a couple things I need help with. First, how do I mark the distributor for removal? I've had big headaches in the past trying to re-time an engine after messing with the distributor. I realize it's not that complex, but I always have problems with it. If I mark everything, when I spin the oil pump via the distributor access, will this mess up the timing, meaning I'll have to find tdc, etc, anyway? Where can I get one of those drill adapters that will spin the oil pump?

Next big issue - how do I rotate the engine by hand? Is there a place I can put a breaker bar or a socket with a breaker bar to rotate the engine?

Lastly, the quadra jet carb that's on it (probably circa 1982) was spitting fuel all over the place when I parked the truck, so I plan on replacing the carb. I'm told an Edelbrock 500 (Performer, I think) is a good reliable replacement. I'm looking for a good running truck with decent power, until I get the cash to build a fast motor. Will an Edelbrock Performer work with the current intake manifold (set up for a quadrajet), or will I need a new intake manifold to match the Edelbrock?

Thanks!
