LA 360 or 5.2 magnum

10-4 and thanks for the info. I didn't know that about the '71. The 360 was out of a 71 Monaco. Although a 2bl it was very quick for a big car and ran very well.
The 91 truck is afarmers down the road and I was sure they had started the Magnums that year. Thats to bad because its a 40,000 mile truck and I would have used motor and tranny in the Dart.
So its going to be a 360/904/ 8 3/4 car

"the 71 360 was a one year only engine that used pistons with a longer compression distance that got compression in the 9:1 range"
So Rusty- does this mean they had a lower wrist pin or how was this accomplished?
