I am looking into upgrading to a stroker kit but I am not familiar with the best options available on the market. I have done a cursory review and noticed Katech is developing a 427 stroker, Ben@Weapon X has one available, and Texas Speed and Performance sells a 416 stroker.
That said, is there anybody here who upgraded to a stroker from any given company and can you tell me how it is working out for you? I'm looking for a reasonable price point and good performance.
Thanks for your input!

If me I have had a 408 ls2 motor then went with a RHS 427 build. both with a YSI are a F1X blower on it.
If I was going with a blower set up I would stay with a stock block ci motor. That said to get a little more power on a N/A motor look at tx speed 416 set up with a good set of heads on it. Robert
After doing some more research, I'm thinking a 416 is probably the best bet for me. I'm guessing TSP is the only vendor offering a 416 kit, correct? Thanks, y'all!

Negative ghost rider....many companies make 416's. That was just an easy example to show from a forum sponser

That's cool. I figured there would be more but I'd rather go through a forum vendor. I might as well go ahead and look at the rest of the package deal (heads, cam, etc) and get this C7 some extra grunt!
If any forum vendor wants to chime in, feel free to do so!
That's correct. The longer stroke makes the skirt of the piston protrude too far below the cylinder. It rocks the pistons, and causes premature wear, or worse. The fix is sleeves.
Ninjaman, yes I was a contributor on GenCoupe when I owned one. But I wanted (a lot) more power so I ended up with a C6. You?

Ditto about the power. I am the guy who really dug into one of the first LS swaps with a Genesis Coupe several years ago and used it as a daily driver.

I thought the sleeves provided more bore but are still the same length. Or are the sleeves longer than the cylinders?

I live in the Phoenix area and will go with Cordes Performance Racing (CPR), when the time comes. CPR has an excellent reputation with the Vette guys here. CPR has built several C7 416's. I don't know if they done any sleeved 427's or would even recommend that build over a 416.
Do you have any dyno numbers? What's your mod list? And I'm from Huntsville.
It made 668 rwhp on 8 psi boost on a very safe tune. It has a TSP stage 1 cam, ported heads, methanol injection, headers, it only has 9.5 to one compression though I would get 10.5 if doing it again. The blower is off of it now waiting to be rebuilt. Holler if you want to see it.

Wow! Impressive dyno, man. I'm thinking if you went 10:1 you might get a good amount of power. Excellent mod list too. Will definitely give you a shout when I am back in town, man!
