6g74 is a 3.5. 6g75 is a 3.8. I think you have the 3.5 sohc 24v motor. The block should be 19mm taller than a 3.0.

FWIW, the 6g72 is NOT an interference motor. I think you are going to find that there's interference with the crossmemember and the pan. There is with the 3.5 dohc rwd motor and the pan.

SRTNate is in the process of doing such a swap (dohc 3.5 into a gen1), but I haven't seen him post in a while on it. I think he's busy playing with remote control helicopter drones
