I finally got my money right to get the machine work done, get all the parts and start putting the beast back together. Definitely learned a lesson and will be a little more thorough and careful this time.

I'm going to start by using the right pistons.
Other than that, I don't really plan to change anything.
I've had the crank machined and the rods & block checked out. I'm just going to take my time putting it all back together, carefully checking all the bearing tolerances.
Oh, and I'm definitely going to degree the camshaft this time.

fuel wash on a fresh rebuild can cause skirt scuffing which could lock the rings up. you wont know until you take it apart. since you have no oil pressure, that should be soon before you make it not rebuildable. i would try to figure out why its dumping excess fuel while its still running.

Just an update for everyone that helped. I finally got her back on the road this past weekend. Took my time, checked and rechecked everything. I've got it purring like a tiger. Oil pressure is strong, sounds great, runs nice. I have a little hesitation at part throttle that I can't get rid of, so I'm still trying to decide on keeping the Edelbrock or rebuilding the old Q-Jet. Thanks again for everyone that helped, hopefully it will stick this time around. I'm getting her cleaned up for a show this weekend, I'll try to get some pictures up before the weekend is over. I'll post them in my thread over at major builds and projects.
