He's going to run SRP, guess he already has them. Just wondering what he plans on running compression wise with the supercharger.

365 Cubic Inch for .030 bore over? Part #142069


So what rings are you going with? The Premium part# J100F8-4030-5 or Sportsman part# S100S8-4030-5? Or something different?

Heads Gaskets I would intall FEL-PRO Severe Duty Part # 519SD




Also roller the whole thing!

Engines done and installed. I went with cometic head gaskets. It ran for about 10 miles, parked it, went to do a fuel sync on it and now it won't start. It's getting fuel and spark. I just replaced the crank positioning sensor and tried another 2 bar map sensor. I'm running out of ideas to try. I don't understand how it went from running to nothing at all. I'm waiting for my buddy to bring a compression tester over. This thing is driving me crazy.

Camshaft sensor.

Make sure that your TDC on #1 is sparking to ensure crank timing to the distributor.

I already replaced the crankshaft positioning sensor, no start. I changed the 2 bar map, fired up ran like crap. I changed plugs, fired up, runs really rich, map voltage is FUBAR'D. I'm on my way to go get another msd 2 bar map. Hopefully this works. If not, I'm going to stock injectors,map sensor and my B&G computer till I can get a good working map sensor! This is retarded. It's running so rich it won't idle and it fouls out plugs. I requested a leaner tune form my sct tuner, maybe that will help.

It's just me but I don't think the stock coil can handle the MSD ignition setup
For instance I have a friend with a "D" that tried using a stock coil and it failed after five days. Maybe it's the multiple spark thing
