How to ID a real MP 360 crate magnum, id the HP rating, and what's it worth?

You know that from the intake? Thanks --- I respect your knowledge, generally. If so I think I'll pass For one thing the non LA intake drilled heads. Magnum heads or not, I'd like to retain LA intake compatibility.

Whoever I talked to on this (estate sale) is supposed to attempt to find more info. I pointed out that I could see a sticker on the head, and that the price may be "over" depending on what it actually 'is'

Yes. Slam dunk.
That’s why @Bobzilla and @273 first asked about what intake was on it.

Street master makes an air gap copy magnum intake.

Mopar had a single plane M1 with Magnum bolt arrangement, but sorta hard to find used. But if you were using a single plane you’d be changing everything else in the motor to need it except the block, crank, and rods.
