Max stroke for L92
I have a L92 2011 engine, and I was wondering whats the maximum stroke I can have?
Is a 441ci setup possible and whats the dimensions
also what are the information for 427ci setup?
Thanks
People more often do a 4.125" and 4.070" combo for the 427, but again it's not terribly reliable due to the long stroke on the stock liners.
Stick with a 4" stroke and 4.070" bore for a 416 if you actually want some sort of reliability and longevity of that motor.

However if you only want 500 plus at the tire that's cake easily had with a 400 plus cube motor with decent heads such as AFR,TFS,LS3 etc.......
and I'm either going to use LS3 heads or LS7 heads havent decided yet
That will give you a 454 cube motor...
call Steve at Racing Engine Development. He is one sharp guy.
Personally I would recommend going 4.155 bore with a 4.000 crank. Leave meat on the walls for clean up etc... with a stroke over 4.000 you start to run into oil control problems which is the last thing you want in a street car.
1st: The WET sleeve it is the best way to go as the the liner & sleeve are removed and a Darton or ERL's own sleeve will be the replacement. Bore sizes range from 4.100 to 4.200. Cost around $1800 to $2000+ may be wrong about prices but will be in the ball park.
2nd: The DRY sleeve it is pretty easy they remove the standard sleeve and replace it with a *longer and *stronger sleeve. Bore sizes range from 4.100 to around 4.185 max. Around 1200+ bucks.
Now that it's football season as the old commercial use to say: YOU MAKE THE CALL.
Mike454SS & Camster are Correct go with a Low lash Solid roller and get the the heads ported = to well over 500 rwhp or 600 fwhp with a stock cubed 6.2* Refer to 1Sick engine. A Lot cheaper than building a stroker if you just want 500 @ the wheels.

I'm very aware of the 468 cube motor Steve did for Hot Rod magazine awhile back in a head comparison deal. That motor received a 4.250 stroker crank.
