Well to answer your question, it has a plate under the carb (spacer) so i guess thats a wet system, but we have the car running now, i appreciate the help, it is definately overcarbed, the plugs were fouled, so we replaced with some nkg's and the guy he bought it from replaced a "modulator" little box, it blows some black smoke, but im sure its just runing very rich, im certain its not butning oil, the valvtrain almost sounds like a solid roller becaause its pretty noisy.

This carb just seems to be dumping too much fuel at idle, (very rough rumpity idle) and flooding it. My dad and i recomended him taking the 850 DP off and replacing with a vac secondaries 600, my timing light was not working right, but i know i have it somewhere between 15-18 advanced. thnx again
