MAX Boost - Stock L94 Short Block w/ E85? Okay guys, what do you think a stock 2012 L94 short block will take with increased ring gaps? Stock crank (machined for 2 keys), Stock Rods, Stock pistons, Stock used bearings.
Engine has 70k on it. Ring gaps would be opened up to ~0.025-0.030.
Anyone know anything about the rods and pistons used in these? My top end with LS9 heads & gaskets, studs, F1R procharger etc, will be used. Think she'll hold the 23psi I have it pulleyed for?

I do have a set of forged rods and pistons, but I was hoping to save the rods for another project. I could pickup a set of cheap H-beams I suppose. The pistons are made for a 6.125, so can't run the stock rods.

If I did anything over with a stock block I would put rods in it if your gonna turn it up. After beating on mine for over a year (saw 25+PSI every time I drove it) I finally wrinkled 4 Gen4 rods but the pistons and block looked spotless. Car ran mid 9's at 4000lbs for whatever power that comes out to.

It looks like the LSA rods are much beefier than the standard LS3 stuff, and they're very well priced at ~29/rod. Might be a good option.
BUT, I'm scared of the cast pistons. I've pretty much talked myself into trying to cleanup and run my old forged JE's. These have very little use, but the skirts are all scratched up from losing the bearing and debris getting sprayed all over the engine. If I ran these pistons I'd use my Callies ultra rods since they're for a 6.125 rod.
I'm ultimately trying to build two engines so I'll have a primary and backup for my race car. I'm trying to go a little cheap on the L94, then sleeve my old LSA block and go a little crazier on that.

You sure about that?
The LSA PN I'm finding is: 12604857
The LS3/L92 PN is: 12649190
In the pictures I've seen of the LSA's definitely look they have more material around the small end than the L94 rods I have:

Same material... slightly different design.
Wouldn't hurt, but for that price your halfway to a forged set. Slippery slope, haha
Don't get greedy in the tune and pistons should be fine. But if you have forged pieces laying around certainly wouldn't hurt throwing them in.
