This NASCAR Engine Was Built 20 Years Ago and NEVER Used! How Much Power Has It Lost? (Ford C3)

What happens here

The engine is moved from the dyno cell to the workbench for teardown. The host and a colleague begin by carefully removing the intake manifold and valve covers. They quickly discover that this engine is equipped with bushings, which the previous engine lacked, suggesting it was a higher-spec build. This further reinforces the idea that this might have been the primary race engine that was constantly maintained. The valve train, including rocker arms (1.8 ratio compared to 1.5/1.6 in the previous engine) and pushrods, is disassembled, and the camshaft is carefully extracted.

Goal: Disassemble the engine's top end for internal inspection.

Tools and materials

  • Engine Stand/Cart — Holding the engine securely during disassembly
  • Wrenches — Removing bolts and fasteners

putting bushings in it to upgrade it this one already has bushings on it so I think this is the engine he actually ran the most back in the day this was the real race engine and they ended up using the other engine in the last race at Daytona just because this one had been hurt it was being freshened up so that's the reason why he didn't have it for that last race when it overheated was that this thing was still at the engine shop getting fixed up from where he had had run it so much before because we look at the build sheets this engine had been built three times in a couple years so this is the primary race piece he really had these or one eight ratio rockers where the other ones were ones uh one five one six if they had been flat spotted after sitting for so long to be rolling all the way over and you don't feel it catch anywhere you know you don't have a flat spot we're having some technical difficulties we try to get the upper washers off because sometimes they can bind around the studs okay it's okay all right [Music] ah yeah there it is oh those look a lot better than the other ones oh yeah oh yeah but what happens is they get mushroomed over so bad up here these heads are probably a little bit soft and they're just squished over so hard are you guys having fun I missed all the fun apparently so last time it was the oil pan that followed us this time is the heads ah this engine's like I'm fine leave me alone hey I made the number you want me to make come on what else you want me to do action when the balancer off cut out all the hard part what yeah that one's got some time on it I think it has some time on it before it got old before it got old yeah the thing is those balancers from ATI you can send them back to them they rebuild them really yeah so you can have like a 30 year old one of these and they'll redo it yep I wonder if people would want to see a balancer Factory comment let us know if you want to I do know JC baby they build these things in Maryland wait wait wait I know what it is all right oil pan bolts go into the front cover oh just like the rest of the front cover how simple and easy to assemble and disassemble all of this is it's not if I see three head engine this is a different block yeah this is a g351 block if you see the code down here I don't know if you can read it not a Ford Guru but somebody in there knows what that is probably older than the other one before they started putting the SVO into the casting because there's no I…
