The quickest way to determine if it's a 300 HP Magnum or a 320 HP Magnum is to look at the cylinder heads.
Under the leftmost exhaust port, if it's casted "R/T" on the head it's a 320 HP Magnum
300 HP Commando- LA motor: dual plane OE copy intake, high swirl production heads (1.88 intake, .474-280-60 flat tappet purple cam) .1993-1994 MP catalog and earlier P/N P4529783
300 HP Magnum- magnum based motor: dual plane OE copy intake, with production heads w/1.92 intake, .385/.401-250/264 roller cam. 1995 to at least 2002 MP catalog P/N P5249498
320 HP Magnum- magnum based motor: dual plane OE copy intake, with R/T heads w/2.02 intake, .385/.401-250/264 roller cam. Sometime after 2002 to at least 2007 MP catalog P/N P5153476

Wow, maybe my wife is right and I am color blind. I swear the intake looked at least to have been fogged orange. Looking at it now and it is obviously bare aluminum.

@67Dart273 so you can look for apart number or just get a picture across the exhaust ports.
That magnum R/T head could be as good as an Edelbrock aluminum head, just iron. It’s better than any production iron head X,J, or whatever.

The 300hp version was a factory Magnum longblock including the cam. I bought a test mule from MP years ago that was a 300hp short block with W2s, a modified factory iron 4bbl, and a 2bbl adaptor…lol. They said the 300hp versions were literally pulled from the production inventory. The 380 was a bit different and “touched” to a greater level.
Getting a 360 fully checked and machined and buying the parts will cost you every bit of $4k with you having a core and you assembling it. I’ve done 1 and almost done a 2nd in the last 8 months and that’s what they cost. So if you worry about quality figure your price based on gaskets to test it down and verify.
