Hey Z51JEFF, I put a new vacuum pump in and did the C17 grounding trick to test the functionality of the secondaries and the seem to be working as described by Marc. I wasn't able to afford the best injectors, so I put Bosh ss injectors in, I have to save up for the best ones. I have to fuel her up as I put a 1994zr1 fuel sending unit and new pumps in. Have the fuses out right now and still have not installed the rebuilt instrument cluster yet, plan on IC, fuel pump fuses, for this weekend. But yea, pressuring up the fuel system before plenum install is a good idea. I tightened up the IH bolts and the breather cover. I really need to take more time and detail the area under the plenum. I really want to start her so I can hear the engine. I am worried about all the marvel mystery oil that was in the cylinders, when we loaded it up on the roll back a lot of oil drained through the exhaust, I removed what I could, she is going to smoke like a freight train for the first little bit. Afraid all that oil may hurt my cats and 02 sensors, I reckon it will eventually burn off.
So if the engine is good and the seller told me it was or is. This winter I will buy the FIC injectors and pull everything out of the valley and do a proper clean up. I'm excited to start her and worried at the same time. I have a 1972 Pontiac 455H.O.bored and stroked, high compression drag engine that I run aviation fuel in but it has no cats and I have read aviation fuel is not good for cats, so we have fuel stations with 93 octane 100% gas reckon I will run that till winter when I plan on long tube headers and exhaust of some sort, maybe hi flow cats. If the engine knocks or smokes reckon a rebuild is in order, I don't even know the mileage yet I'm hoping when I put the IC back in it will pop up, seller told me around 80,000. Sorry if I'm rambling getting excited. I need to clean the pulleys radiator, I have read trash gets in between radiator and oil cooler and ac condenser. I am going to need tires, brakes and the passenger side headlight needs gears. A lot to do, but I'm getting there, I appreciate everybody's help, you guys have been great and very helpful.
