where I need it the most is above 6,000. This boat is under 5000 lbs with 2 of these motors. I don’t need any extra torque. I’m sure these motors will have more horses and ft lbs than the old school 5.7’s that came out.

The old 5.7 and big blocks vs LS engines dont even belong in the same category. Light years ahead. Yours will be a goid runner just not optimal intake for rpm range of a boat but will mske good power regardless

What engine did you have?

under 10/10 loss below 5000 rpm’s on a 6.2. But above 5000 should be 15-20 gain. It’s what I wanted. Upper end horses. Broad power curve. It will still make more power than the 5.7’s from 1500 rpm up.

that intake design is no different than a 525 efi or the intake that came off of the 5.7’s. Straight runners with an open plenum.

I just realuzed it is fitech. I tjought it was holley sniper intake, which is the one I tested before. Very similar design but have to testing on that intake to backup previous statement as it is not the holley. Disregard

I like the remote coil mounts.

Pretty cool setup honestly. Nice tight little package. Well done OP!
Plus its an LS and we all know they rock (make big power and a monkey can work on them)!

You almost want to go straight to a museum so it doesn't get dirty. Beautiful.

BTW - Does anyone have the dyno sheet/numbers for a stock Merc 330 or 420? I'd love to see how the torque numbers compare.
