Free 383 for Blaze

[74Blaze]

Longish story. Blaze has not been running well for over a year. After throwing new parts at it, checking for vacuum leaks..., I finally came to the realization that it more than likely jumped timing. I put the current engine in it in 2007. It is 290 HP GM Crate 350. Yes, I could put a new timing chain in it, but I have just received a free 383. The 383 came with the '55 Bel Air that a good friend of mine purchased last year. The story goes that it is a fresh rebuild (built ≈20 years ago) that was never re-installed in the '55. The owner had a stroke and never recovered well enough to finish the re-do of the '55.
So what I know is it's mid-90s 350 Block, with mid-60s Corvette 2.02" Heads. What I've been told is that it has 11:1 compression and a Lingenfelter Cam. Also, in it's previous configuration, it was running nitrous. Bore Scope shows that the Pistons look new and have Valve Reliefs on the tops. I'm still trying to figure out exactly what I have. My main concern is whether it has a realistic Cam for my trail-rig application.
Picture of my current 350 and a few the 383 are below.

The Z part number comes up as an old comp custom lobe of 250@50 with 501 lift on a 110 lobe sep which if it is 11:1 makes sense as it would be an older lower lift version of my 388 cam. its gonna be a race/bracket cam that's gonna want a 3k stall converter idle fairly rough and is gonna need high octane fuel at that compression ratio ie 91-93 depending on tune,cooling,etc. or race fuel ie.100-110. It's going to be the complete opposite of what you want for a 4wheeler unless you plan on being wide open the whole time.

Just what I could find im at work and a quick googlefu on my phone so might not be correct.

Yep. That's what I was afraid of. They guy used the '55 as a street racer back in the 80s & 90s. I'll need to figure out what Cam I want in it for my trail rig. I don't mind the 11:1 compression as I'm thinking that it should run fine on 91-93 octane with the right Cam. No need to worry about the stall speed as I'm running an SM465 manual.
