Impressive, but i would wait to see what happens after 20+ passes...

From the YouTube vids i have watched, they get a few passes until the bearings, crank, rods, block fails.


It's always entertaining!

Around 3:00, he says "the engine's been together for about 6 years".... I'm guessing that's more than 20 passes.

Oh, he's been here! He "liked" my post, before anyone even replied!

Yeah, he listed most of the build. "It was a budget build..."
*Stock block...been filled
*Scat Crank
*Compstar rods
*DSS 4032 alloy pistons...they're not even a 2618. So... you know. (what ever that stuff means!)

Does "filled" mean that they filled the coolant passages with something to stiffen the block/bores? Or maybe his father-in-law helped him prep the block?

If it's a LT1 it's 99.8 % chance it's a factory block. There isn't a generally available aftermarket block. I read a while back on a different site of a guy converting aftermarket aluminum blocks to reverse cooling. The question is what's considered stock.

Yep. Filling the bottom of the jackets to make the block stiffer.

Weight! the pre 68 blocks and heads tended to be heavier. Some of the later casting became undesirable because they were too thin. Block filling for strokers is more common because the are at the base of cylinder tends to be the thinnest area when notching for rod clearance.

Yep, I would expect that cooling suffers enough that this is no longer a realistically streetable engine. It's good for 1/4-mile at a time. In my book, it's no longer a "stock block" engine, but whatever.
