It's kickass to see someone run a 3.99 with a sleeved factory block. A few of my LS guys are talking about going for a 3.99 pass with a factory block, this is the inspiration they needed. 2024 is gonna be great.

Exactly compitition and bragging rights breeds better and better builds.

Its cool for a record no doubt, but its throwing money into a fire to do it. Its a toss of a coin, if that motor will last more then that pass, then rebuild and repeat. Eating a motor one time, is gonna cost you way more then what the sleeving would have, so its not worth it to 99.8% of car people.

But the LS can be had from a junkyard and run that for $400. Not a big loss.

At insane power levels a stock XXX is a dick waiving game and not much more.

I think Brett's predator block has some work also in some of the outer jackets to beef them up, but you guys would know for sure.

For the LS, Dylan Kato went 4.20 or .21 at LS Fest with a sleeved LS block.

Capiz thinks he can get a 4.doh with factory sleeves, he's gonna give it a go.
I think it has some webbing that the regular coyote block doesn’t, its not added extra though that’s factory on that motor

In the case of Lasala's motors, they haven't lost a rod or even a bearing. The last motor tear down Lasala said they saw some metal in the oil and changed bearings at the race. It was just starting to have issues in a couple bearings. That's due to the stock crank flexing versus using a billet crank. That motor I think they said had like 28 passes and the street miles on it. The motor tear downs before it were mid season tear downs. They have been finding issues and developing ways to correct those issues.

They were building a back up motor with a billet crank. As it will solve some issues and be more reliable. But for a motor making north of 2600-2700 hp, it's pretty happy.

I think the 3.99 pass was with the stock crank motor and bigger turbos than they had been running. So maybe they will get even more out of it.

Doesn’t an iron block hold up to more without being sleeved? I just assumed they sleeve the coyotes due to the block being aluminum

Correct. But you can swap in sleeves made of stronger metal than the factory steel sleeves. In some cases the blocks can be machined to offer a thicker sleeve as well. I'm pretty sure the coyote is not one of those motors.

I must of read what John posted wrong, thought he said stock sleeve block, as in not aftermarket sleeves.

I was under the impression they used spray in metal to do the "sleeves" of a Coyote. Wanting to say Lund's car has sleeves, and MMR definitely sells them.

No, you are correct. I thought you were making a general statement.

The 2013-14 GT500, GT350, 2018+ Coyote, and Predator blocks have the plasma-transfer cylinder walls
