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

What happens here

The engine undergoes several dyno pulls, starting at lower RPMs and gradually increasing. During the pulls, performance data such as horsepower (HP), torque, oil pressure, and air/fuel ratios are recorded and displayed on the dyno console monitors. The operator carefully monitors the engine's behavior and performance metrics. The engine ultimately reaches an impressive 722 horsepower, which is surprisingly close to its original 733 horsepower rating from 2004, despite the long storage period and visible rust.

Goal: Measure the engine's current horsepower and torque output.

I emptied this entire can in the engine did I see that number right yeah this one runs what yeah this one runs maybe fog is Magic I don't know uh what the heck some of them all right so here's the deal look so this is the dyno sheet from December 2004. really this thing made 730 8100 RPM 735 and 83. yeah and the lines you usually got to get a couple runs in there right right you average it out and it was pulled this back then it was only important about we'll call it five inches of vacuum and you're going eight inches of vacuum now well vacuum makes a whole lot of difference yeah so it was maybe that dinos like not broken in like the Rings weren't suited completely and now the rust inside made it seal what are we doing here Dad said this is the engine that was brand new that's never been in the car it was freshened up and set down and never raced saffron 19 years the Springs were compressed too everything like you didn't touch the Rockers did you no no so that's myth busted oh God yeah oh totally yeah that's the acorn of power that's it well what I'm screaming is this might be magic I don't know so you're saying this thing aged like a fine wine on the floor of the garage 190 degree oil temperature it was right at you know 81 pounds of oil pressure and you're where are we now you're a 193 right you're right there at it for it 61. now this was probably back in the old days it's probably like 20 50 as it's probably the old 76 20 50 more than likely for everybody around is this the 1550 or the 1030 Dyno stuff you guys use okay that's it 32 degrees timing yep interesting the other one was at what 28 I think when we ran the other engine saw it did it like more than 28. I don't remember what it was yeah I don't remember it was 28 we can't strength remember is this a nine to one engine oh no this is 14. yeah yeah that's one reason why this one runs a lot better is a lot more compression yeah obviously I think Bobby built this one for Dad so because you know Dad's been down on power everybody else he's like well here we'll we'll tune this one up okay but then he never went to go run it so either got a chance to run the one that was tuned up a little bit white wine through the fuel yeah I want to drop to it 10 pounds below eight nine ten eleven pounds see it's gotten a little bit leaner through here huh but it it feels different and then it gets leaner as it goes past it but everyone's a little bit different for every motor so this is where Bill pink would go in and…
