Engine experts input needed on used engine
Finally got around to pulling apart my engines and would like some insight as to what I have. The engines started out as 94 502 mpis.
what I've found so far
Block - GM 8.2 cast on side
Crank - seems to be stock (cut) casting 14097044
Pistons - JE 757F
Cam - CC 3114 3110 HR114 and F5284 engraved into end and 139516 95C2B stamped into cam near one of the lobes.
Heads - Merlin 1-043B (345CC Intake / 119CC Chamber, Rectangular Port – Cast Iron BBC)
Lifters - roller joined by bar that says up (no other markings)
Push rods - 3/8" no other markings
Rockers - Crane Gold 1.7 ratio
Computer was done in 1997 by ASM but they have no record of what was done (sticker has date)
I'm starting to think these were set up as blower motors and when the boat was sold they pulled blowers and threw on stock flame arresters. I'm not much of a motor guy and trying to figure out what I bought. Thanks in advance.

You can find the book "rebuilding the Gen V/VI Big Block" on Amazon for Kindle- much cheaper than the hard copy version which is hard to find.
Search for ISBN B0027G6WY8 by Mike Mavrigan - has all the parts, castings, etc. Covers stock and GMPP parts, but is not a book on mega HP builds. Best $6 you will ever spend
or 1613250525 - not sure if this covers Gen 5 and 6...
