Not sure that I trust these numbers but it's something. I've seen slightly different HP/TQ numbers quoted and several sources that swear the 360 was also bumped to 9.2:1 compression. I want to say that Mopar Action did an article on the magnum motors when they came out, and compared them in detail to the LA blocks, but I haven't been able to track it down yet.
Sorry, P5249498 is the OE 360 tbi cam, also the 360/300 crate cam, 274/264, .385/.401. As a side note, the 360/380 crate used P4876348, which was 288/292, .501/.513. Unfortunately the 360/380 cam is disco'd.
Can you post the specs on the 318 LA roller cam, please?
