I recently bought a 1991 LX 5.0 that was stock minus a cam and exhaust. It ran fine minus a few exhaust leaks.

I just finished installing a set of ported Windsor Jr heads, GT40 intakes, 75 mm throttle body and matching MAF and also some new 24lb injectors. I also installed roller rockers and the correct length push rods. I replaced all sensors, vacuum lines, spark plugs and wires as well.

When I went to start it for the first time, it just spins and has 0 compression on the number 1 cylinder.

Does anyone have any idea why this would be?
