6.0 stroker build. I need some constructive criticism for a build I’m drawing up. Experience engine builders tell me if I can bore my iron 6.0 block to 4.065 with a 4.125 crank and 700 lift solid roller by Cam Motion. This just a idea but if it works I’m pulling the trigger all comments welcomed. Lil nitrous in the future
Noooooooo! A 6.0L has thin and short cylinder walls. It's the worst block for a stroker, but people use them because they're easy to find. Personally the most I'll go is 4.030" and 3.900". Aluminum blocks have 1/8" longer cylinders which make better stroker motors.
Probably be all right for NA and a little NOS as long as you're prepared to be going back through it more often since its not a street engine build. Seems everyone these days thinks it's the cats meow to throw a big crank into these short sleeved LS blocks and then throw on the band-aid by running shorter pistons and finally top it off by spraying or boosting. Yeah you'll hear it's been done many times over and I have no doubt that there's truth in that statement!
I'd skip the 6.0L block and go straight to a sleeved block for a stroker w/ nitrous.
There are a lot of advantages both in performance and longevity by having a sturdy cylinder wall that is the proper length.
I've read many times about guys with 408 strokers having piston rocking issues, premature wear and ring seal problems and these are compounded when boosted or sprayed.
You could look at a 6.2 block for about $2,400, TMS does a Darton sleeved block using your own block also for about $2,400.
Not easy to spend that kind of coin on a block but I think the investment initially will be well worth it when you hit it with a big shot of giggle juice down the road.

That’s because their engine builder and/or piston choice sucks. Wiseco makes shelf pistons for 4” and 4.10” stroke LS engines that don’t have those issues. I’ve got custom Wiseco pistons in my 6.0L block with a 4.250” crank and I don’t have those issues .

How many cubes is your 6.0L with that 4.25" stroke crank?
On the 6.0L iron block, I think the cylinder wall gets too thin over 4.030” for significant power adders. They seem to want to crack between the bores when you get into the 4 digit horsepower range. Going even further to 4.060” or 4.065” would be fine for NA or maybe a teeny little bit of boost and a babysoft tune, but I would not spray it.
