I’d be concerned about that torque curve. It’s more a tow truck engine than a dragster. But I’d be interested to see the results regardless fishstretcher. That L92 6.2 LS is a beast and has an aluminum block. The ability to get bbc numbers out of a small block is amazing today. Also, Volvo is now using LS blocks.
One other thing to consider on that bracket. I always thought my transom was rotted due to poor fiberglass 1 layer of 6oz cloth with holes is not the best plan.
But I couldn’t figure out why there were so many drain plugs on the boat. There had to be nearly 10 onboard. 1 in each drain area on deck and then several in storage boxes and the one on the stern had a wire keeping it there when not in. A couple of months ago it hit me that my boat was so stern heavy, he had to put drain plugs in deck drains to keep water out.
They likely seeped along with the transom and the water got down in bilge and caused my rot issues (or at least helped it along). Food for thought on your project.
