i measured the block from the 6g72 and also the block from the 6g74m, its same from the end where the pan hits to the top of the short block. i also removed a head bolt from both and the new one is longer, from the marks on it where the head hits the block and the head gasket are longer i need to get a micrometer, as well as look up some serials on it asap i would be extremely happy to find out its a 3.8 but i can wish even if its a 3.5, hell ill just be happy when shes in, i have it on cherry picker now just taking a small steak and beer break, but the heads are larger strangely enough and both motors are dohc. this thing is hiding something, i had the cell number from the guy i got it from, it was already removed from the vehicle it was in and he said it was a diamante but it has 3.0 on the intake manifold from the diamante, someone mighta done work to the other car but it only had 41k on it supposedly a grandmas ride that was rear ended. shes getting bolted in right now. ill post what happens <img src="/forums/images/graemlins/scared.gif" alt="" />
