Maf???

Maybe a dumb?? Anyway I did a LQ4 swap into a 1981TTA, add LS6 cam, springs, AeroForce Int gauge, and 7.45 push rods, oil pump. Stock truck intake, and had the VATs removed. The engine starts, but runs rich! The MAF reads 1.29-1.39 at idle. I didnt get the MAF with the engine, I got it from a truck with no engine, and it look the same. Do I need a MAF for the LQ4 for it to run right? FP is 60-65 at idle. It so rich it shuts off after a few mins.
