"I recently purchased a used engine for a boat project. The seller believes its an OMC based on the orange color, he removed it from a damaged Chris Craft.I am rebuilding the engine and would like to know the original HP, torque, CR and anything else of value. It is a 454 GM, came with a 1:1 older,I believe, 1017/001 model velvet drive. Think its based on a GM truck engine. the following is what I have been able to determine so far:
1) 4 bolt main block casting# 14015445, GM F099 I
believe is the casting date, don't have a clue as to the next one: GM 3P CFO
2) 7/16" pushrods, 8.27" intakes and 9.25 exhaust
with manley guides
3) cast iron oval port heads, casting# 14092360
with screwed in rocker studs
4) cast iron GM intake manifold casting# 333841
5) i am guessing the crank is cast with# N353039,
casting date K283?
6) forged I beam connecting rods
7) flat top aluminum pistons with valve reliefs,
#1 and 8 pistons have a circular depression in
the top, purpose of which escapes me.
8) it is fresh water cooled
9) 4V Quadrajet
10) Delco Remy electronic distributor.
11) hydraulic lifters
I plan to assemble the engine myself after minimal
machine work as it appears to be in very serviceable condition, so far only on a visual assessment, with the pistons the only mandatory replacement due to a couple of cracks plus the routine bearings and such. The heavy duty components,it would seem, would make an unbreakable 375-400 HP engine with reasonable $ investment so it would be nice to know the pedigree of the motor even though a decent mechanic for a price I am sure could tell me.
Any help or suggestions would really be appreciated."
