The 6.2 and the 6.5 were both designed by detriot diesel. They share no similarties to the 350 whatsoever. I dont know who the hell started this crap (I have had more then one know it all dip**** try and tell me the engine in my H1 was a bored out 350) about the 6.2 and 6.5 are bored out 350's but they are wrong. The 350 diesel was designed in the late seventies and was the first diesel pickup chvey offered. It was a very poor engine which led gm to contract Detroit Diesel to design a new diesel for the chevy pickup trucks. I think that the D-max runs about five grand and the Allison runs another 3 or so, but I could be wrong.
