I have a 420a motor. Its bored 0.020 over with Wiseco 8.8.1 pistons. And I have Crane cams part number 431-0012.

I can not get it to start, everything is new. All the sensors are new, I got spark and gas. It fires off ever so often but wont stay running. Any ideas?

Are the cams too beefy for the ECM.

What's the compression supposed to be on all the cylinders?

Really need my car for work and don't wanna have to put back in my other motor
