Dimpled Cylinder Walls
I wonder what sleeves ERL used? I talked to a rep at the Darton booth at PRI and he said they had supplied sleeves for ERL at some point but it didn't sound like they were the only ones.
Been talking to Steve. He's doing a new block for me. I considered going with a 4.155" bore but decided to go back with 4.185".

I've read quite a bit and never heard of a cylinder bore cracking because of RPM, nor Excessive Piston to wall clearance. The wall clearance being to much is the worst thing I see listed. Thin Walls or a bad set of sleeves sounds like the problem. Also if you have dimples sounds like debris as anything dealing with pistons and bores generally leaves scars.
Sounds like a winner! There are a few guys running that combination and revving it. Correct pistons Fix most known problems, so if the pistons weren't hurt then what? Bad set of sleeves added with to much play with the pistons & walls. Maybe, but bad sleeves is what I guess.
Call up ole uncle Steve @ RED he's post here also. To actually get some Factual based knowledge from experience. Hope you get it corrected, it sounds like your already at it!

So I got my NEW 5.3 block from Steve (RED) but took his advice and went with 4.155" bore although Steve said the 4.185 would be fine but 4.155 would leave room for a clean up later on. Now I'm at the mercy of Wiseco who has already changed the shipping date for the pistons.
So...
- Long Stroke,Short Rod = High Side Loading + Thin Wall due to max Bore
- Excessive Piston to wall clearance, 7800+ RPM Magnifies all of the above
- Poor quality cylinder sleeves
- The Domino effect of stacking intolerances
= an expensive lesson to me and a caution to everyone else with an engine from ERL!
Not an expert here, my .02 both Spanks13, & Slogo are correct.
Long Stroke,Short Rod = High Side Loading +Thin Wall due to max Bore, now add perhaps
Excessive Piston to wall clearance, 7800 RPM Magnifies all of the above.
The Domino effect of stacking intolerances.
Out of Curiousity what oil brand and viscosity.
Sorry for your loss.

Staying with 4.125" stroke and my goal is to have a well built LS engine instead of the crap that I got from ERL. Maybe this time I won't have oil in the combustion chamber because cylinders sleeves are f*cked. Going back with Crower shaft rockers and a few other improvements.
Since the car has been down dropped some weight with a 8.50 cm cage and some suspension upgrades. Hoping to knock some off the 1/4 mile times.
