99 FL60 mutt/conversion/repower project build

Ran across a guy parting out a 97 FL70.. engine forward including accessories cooling stack and electrical harness for $800.00
6cta 8.3 250HP with a 12mm pump
Been sitting for 5+ years.. supposedly got over heated... Coolant look good and so did oil..
Figured I'd jump on it while I could..

had head/valve job done on the 454... 8,000 miles late on said valve job... and machine shop said "we don't make mistakes"

Running for new company now... hopefully make progress on the mutt 2.0

And keep thread open so it doesn't lock lol
 
Looks like detonation.
I couldn't imagine doing what you do with a 454.
Unless you run 55mph on flat road.

Hauled a cat 3512 engine and cradle from SLC to San Antonio... It's a turd at 10,000 feet lol with 15k on the deck.. 4.63 grears helps a lot 70 mph with ~2500rpm with NV 4500

Detonation would show up elsewhere
 
Drove over to Zach's shop, North American Turbo Systems, had them swap the compressors and related items in my 362/68 and 366/74 around.. now I have a 362/74 balanced and ready to go..
