Lake Speed's Forgotten NASCAR Engine is READY TO RIP! 90's Ford C3 with Modern Tech Dyno Test

What happens here

The fully assembled engine is mounted on the dyno (dynamometer) for testing. Initially, the engine is run with E15 fuel (current NASCAR race fuel) and break-in oil. The first pull on the dyno measures the baseline horsepower. Adjustments are then made for subsequent pulls, including installing a custom-built Bill Pink Race Carburetor, changing the fuel to VP Q16 (leaded race fuel), and swapping the break-in oil for 0W-16 race oil with friction modifiers. Oil samples are taken for analysis to monitor engine health. The dyno operator monitors the air/fuel ratio and makes jetting adjustments to optimize performance. The final dyno pulls are conducted with the optimized setup.

Goal: Measure and optimize engine performance (horsepower, torque, air/fuel ratio).

of one of his favorite race cars. Today is the day. Today's the day. Finally the day. [laughter] And we have both lakes here. What was the most power you ever saw on your engine dyno that was in a car that you raced? about 7:35. Really? Yeah. Whenever you were meing, how much power were those cars making? You have to tell me. I don't They were They're about that. So, this this could be the the most powerful car that you've had in a a cup chassis on a road course. Yeah. Be nice if they're running against get against get against get against something some of the stuff that we were running against. Well, if you go back to VI with this thing, it'll be a lot more power than you had last time. Remember the last time you were there with Dave Dale Felon? I was out on the straightaway after off the oak tree turn. I'm out there hitting second gear looking rearview mirror and I see him come around the corner and he went by me before I got down the straightaway just like a rocket. I went, "Forget this." [laughter] In October 2002, it made 690 on its best run. That was a real number. That was a real number. Made 690 in 2002. So, we still don't know why it was so low on our first why it was 480 last time. Have no idea. We still don't know. That's the great mystery. We never figured that out. No, there was no think it got high. If I can remember the thing to end the race is to make sure it finished cuz I had pretty good size lead so I could slow down. Same block, same heads, same manifold, new valve train, same rod. We found out the rods are older than both Jackson and Benjamin. Two of my kids. brand new pistons, new ring package and all that. So, we'll let them do all their normal stuff. Then we're going to have some fun and we'll put on this. We'll put in the Q16 and put in the 016 oil. That'll give us a really go for it. Oh, yeah. So, there's going to be two phases to this. Oh, yeah. Yeah. Yeah. Yeah. It's like, okay, what what does she do? Call it the the normal way. Then we'll pull in all the fun stuff. So, this block looks a lot different than the last time we saw it. Can you explain what you guys were doing in here while we were flying all over the place making videos about all the parts that are going in it? We updated the the valve train, the lifters. We checked the line hone, honed
