Brian here is all the info I have on the motor, 502, 814 HP on dyno, solid roller lunati cam, Lunati rods and pistons, Roslen 400 turbo, 6000 stall, 9"w/488s, Fiberglass third generation Camaro body weighs 2471 lbs with me in the car! I bought this car complete so anything said we will just have to wait and see, right now I am in the process of putting in an all new MSD ignition system. When I get back to the fuel system I will double check that pump but I have to pull the rear bumper section to get to it! This is my winter project. I also saw on Pro Systems web site an alcohol carb with a regulator where you run a vacuum back to the regulator any thoughts on that! Thanks Mike
