I dont think anyones against him. But if we're talkin shop, lets talk shop. He's made about two dozen claims in this thread, that are simply untrue. Things like his engines are going to run circles around a 525 merc, use way less fuel, his single pattern cam will make more torque than a dual pattern, and so on. Why not just start a thread, list the parts combo, and post the results. No need to speculate, bash big blocks, and make false statements...I mean, he claims his engines are so super efficient, yet no fuel flow data posted nor gathered on the dyno runs, and the BSFC numbers were nothing a decently built big block cant achieve
The LS engines been out for OVER TWENTY YEARS!! Its time guys stop acting like they defy the laws of physics. Sure they are a nice platform, but good lord, they arent magic. They are a friggen pushrod two valve V8. lol

fwiw, crude intentions engine was dynoed in full marine trim, wet exhaust, all accessories, sea pump, etc. Not stripped down with race car headers , etc. Theres some parasitic loss there, which also affects bsfc numbers. A fully dressed marine engine, like how mercury dynoes them, will never see the fantasy brake specifics, esp the forced induction engines.
You didnt dyno with marine wet exhaust, sea pump, circulating pump , etc, MGG? I dont recall

Just sayin. He made it sound like a pretty much stock motor with ported heads. This is exactly why I prefer conversation face to face. Too much misinterpretation

You know what is really boils down to I built it. I stated it. I missed my mark. I still posted it knowing I would get ****. Ran it again made some gains. Missed. Still posted. The point is I had the balls to do it. I gave it a shot. I showed the public exact results with stock ls3 heads. Ive never been anti big block I had them. Been there. Done that. No hatred. Just trying something different. We are all boaters here. What or who am I hurting by posting some data. Im not the guy who beats up or bad mouths people on here. I try to inspire them. I owned up to my end. I always will. Btw I really would call my engines built but you choose what they are.

Thank you. Like I said in an earlier post I will update at end of season when cnc heads go on the motor. Again. For comparison sake.

most of the runs are with it. We blew the rear seal after the bearing locked up. Had to remove it. I have like 15 pulls. Ill find out how much it pulled for hp

for the record I’m a fan of the LS platform and think you made great power for what an LS is. I only take issue with the claim it would make a 525 look like a fool through the whole powerband and I don’t see where you beat the 525 at all. You make peak power a little higher but a fraction of the torque. This is no ball busting on the LS or what power it made just against the claims made.
You also mention there aren’t many LS powered stern drive boats yet claim they’re cheaper and better. If that were the case don’t you think there would be more than 20 of them?
