They sound pretty good cruising down the lake at 2800-3800 rpms too (Imagine what it sounds like at 6000+!!!)

Here's my beast stock 5.3l with twin 62mm turbos running on Holley HP EFI. Best its done so far this yr was 68mph at 5700rpm at 7.6psi. pushing a 25ft pontoon

Motor is a stock Gen III 5.3l with a LS9 cam, Yellow springs, High Volume oil pump, and LS9 Headgastes/ARP studs.

I'm running out of water pressure on long runs with the 2 stage water pump, going to have togo to thru haul pick ups I belive.

I also have exhaust cut-out and I like the quietness for idle around the lake, but the thing sounds oh so nice at 5700rpm..

Here is a few videos of it before the cut-out were added(wife didn't like how noisy it was)

First run

Better one(had blown headgaskets) have since been fixed

They also stand behind their product with a warranty and I know they have ski boat motors based on the LS platform with over 1000 hours on them and still running strong.

This guy has some good words of caution when adding stroker kits https://www.youtube.com/watch?v=VsmbbuSq9m0

Going to pull it apart and see what I find. I'm also planning on upgrading the heads I have on it to hopefully make some more power.

Awesome buddy, hope you get it all worked out over the winter. I'd love to see it in person next year @ Cumberland.

Keep us updated over the winter on the progress!
