Probably like every one else I've wondered what a 4 cyl ag deisel in a pickup would perform like. I might have the oppurtunity to find out, my son got his grandpa's '78 1/2 ton chevy pickup with a bad in line 6 motor. The body is in great shape so he's wanting to repower it with something difffernt. I'm not too concerned about the physicals of installing the motor, we have a fairly complete machine shop, but I'm wondering about engine RPM and speed. Assuming a 3:73 rear end and std tires we need about 2100 RPM to make 60 MPH. The Deere engine out of a 3010 has a rated RPM of 2200. I'd like to get that down to around 1800 to give it some room and not run right against the stops. That means I need to overdrive the trans or find a really tall rear end, something in the low 3's which I don't even know exists. Looking for anyone's experiance with this idea..Thanks!
