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

What happens here

The engine is unbolted from the dyno and moved to a workbench for disassembly. The goal is to fully inspect all internal components. The host begins by removing the top plate of the intake manifold, revealing epoxy work inside the runners. The spark plug wires are detached, followed by the valve covers, exposing the roller rockers, pushrods, and valve springs. The distributor is pulled out, and its gear is inspected, showing significant wear, indicating an issue with lubrication or material. The intake manifold is then removed, revealing the cylinder heads and lifter valley. Finally, the cylinder heads are removed, allowing inspection of the piston tops and cylinder walls, which show signs of carbon buildup and sitting marks, confirming the extent of wear and the head gasket issue.

Goal: Disassemble the engine to inspect internal components and assess wear.

part okay and you get to come along for the ride i know we got this thing off the dyno you're gonna are you gonna uh spearhead the tear down oh yeah i'm gonna tear it apart all right my curiosity won't let me go home and just not know i gotta know i was really i was really hoping we were gonna do this today because like i don't want to wait another week and a half a major cliffhanger well especially now right because the question is as the guys noted based on that horsepower output is it actually 358 cubic inches yeah it may not be you know there were some small bores small cubic inch stuff that was being done in road racing at the time yeah so this is the blow-by gauge we were looking at while we were dynoing it and we thought it was about five but actually it was about seven so just a regular old small black chevy is gonna be somewhere around two two and a half this thing was up here about seven but that's still at 200 horsepower yeah that's you know you'd like to think every uh cfm is 50 that'd be nice but that's not the case so was this this c3 is that c for cleveland what is that what does that mean i don't know anything about any of this how is this how far straight is this from a 351 windsor is there anything in common with that the heads are similar to the old 351 cleveland as far as that's kind of where the head is very similar or it has similarities um the block is a windsor would be a windsor cam line okay but when these things came out in the late 80s early 90s when they started the main lines was a cleveland so the two and three quarter inch stroke or main journal and so that was basically it was a kind of a combination it had a windsor layout on the short block different deck height than the cleveland or a lot of them were some of them were the the deck height for cleveland was a 9 200 some of these are 9 200 some were 9 500 and then later on they became 9-inch okay but this one we're going to find out i'm guessing it's a 9 200. but um looking at the block and the freeze plugs this block would have been had to been after i'm going to think after 94 94 to 98 would be the year i would think this block was so is and this is an svo block is that what it's called so it's like cast by ford sold for their performance program to race teams that's right is that where these heads originated to that's what the heads are yep they they made a lot of these heads yeah robert yates did a lot of the early development on the cylinder head yeah um and then…
