can't get the 283 to crank
My 1951 F-1 has a 283 in it. Before I got the truck it sat for probaly 5-10 years. I don't really know. I tried to get it to crank but at first it would not fire on the plugs. I replaced the spark plugs, wires, distributor cap, points, rotary button and condensor with new parts. I took the coil off my maverickand put it on. I managed to get it to fire on the plugs. It is a mix off red and blue fire. It is still weak. I have a practically new battery with 750 cold cranking amps. I can't think off anything else ignition wise. When I got it there was no carb on it. It has an offy 360 intake on it. I put a holley carb on it. I have tried to crank it on gas and starting fluid. I have got it to were it seems like it's about to crank but it won't. The motor has set and it doesn't have much compression. I've basically run out of ideas. Any help would be appreciated.
