Lake Speed's Ford C3 NASCAR Engine: Time Capsule of 90s Technology! (Dyno & Full Teardown)

Watch on YouTube

What happens here

The video introduces the project with a Ford C3 NASCAR engine, estimated to be 20-25 years old and an early 90s specification. This engine was previously used by Lake Speed Senior in his 1992 Purex Thunderbird for vintage road racing. The team aims to get a baseline power reading after the engine has been sitting for approximately 20 years. The host explains the significance of this older engine technology compared to modern counterparts, particularly in terms of piston ring thickness and overall efficiency. The dyno test will also measure critical engine vitals, such as blow-by, to understand the engine's current health and identify areas for improvement. The ultimate goal is to dyno the engine, then tear it down to inspect its internal components, and subsequently modernize it to increase its power output.

Goal: Understand the project goals, engine history, and initial dyno test objectives.

this is like a time capsule of what cup technology was you know 20 25 years ago you've got a purex car out here if you don't want to do something put put the motor in something it bolts right in there you can still drive a stock car huh oh you ever driven a stock car like recently uh what's recent so he's saying we get that engine freshened up put it back in that car yeah and get you back in the car we're at pro motor engines right now with that ford c3 in there that we pull out of lake speed seniors garage with lake junior who's the the marketing tech guru at total seal piston rings and we're gonna get a baseline on that engine to see what it does after it's been sitting for how long uh about 20 years okay long time and he used the vintage road race with that engine in one of his old cup cars didn't he yeah so the one you saw on the last video uh the 92 or 83 purex car that 92 thunderbird he hasn't been he vintage raced it actually saw one of those last races and you know like he was saying those guys had modern engines and all that he was way down horsepower compared to those guys with this old engine which is this is era you know probably early 90s spec type engine so early 90s cup type engine yeah early 90s cup type engine to what this thing really is so this is a ford c3 a c3 heads what does that mean for somebody this is like a windsor based block right yeah so this is essentially what a cup engine was a ford cup engine was in the early 90s of course that was a 92 thunderbird that he was racing so this was supposed to be the type of engine that would have been running in that car at that time because dad was trying to keep to the spirit and the intent of vintage racing uh which thing i heard in the other video those guys escalated it and there were cars that were four or five years old vintage racing is like that's not fair so interesting to see how this the engine actually does relative to what we know was at the time a 2003 2004 engine he was racing against well here's the part i'm really excited about so this is like a time capsule of what cup technology was you know 20 25 years ago you know i know that at my time at joe gibbs racing and the engine department doing the development of the oil program an o 43 piston ring for example was like state of the art in like 2002. today they run a 0.5 millimeter ring that's like half the thickness so explain that to people who don't understand what what exactly piston rings are you're talking about the…
