5.3 LS into a Four Winns U17 - Build Thread
#31
I actually did use the keyway. My motor is a LS2 that has been stroked to a 408 and the Callies crank shaft I used was keyed.
Here is the bracket I built. Its not the prettiest. But when I finally see that it all works, I'll build a nicer new one.
Here is how I got around using a circulating pump. Moroso makes some adapters that takes the LS water pump openings to a standard BBC. So I used those and ran a Hardin stainless crossover. Moroso also makes a Remote Thermostat housing that I mounted to the back of my seat so I was able to keep all my hoses equal length keeping water pressure equal to both sides of the engine.
Here is a pic of my motor after I dropped it in a week or so ago. Same thing, don't judge my bilge area. I am just getting it running for this season, then next fall the motor will come back out and I'm repainting the bilge and re gel coating the transom because I'm also adding k planes, hydraulic steering and an aluminum swim platform.
If you have ay questions about what it takes to make a marine LS motor, don't hesitate to ask. I have been working on this for over a year now. I am within a week or so of having it all done and water testing. Pretty much just waiting on my new gauges to get here.

that`s Scott`s boat. Didn`t know he had reversion issues. I`ve driven his boat, screaming fast and run it WOT for extended period no problems. Just talked to him a few weeks ago, he said he swapped out the smal lblock and has a stock 496 in the boat. Tried uploading my video from youtube but it doesn`t let me. What`s the issue here
