These are starting to show up more in some I/O apps but are expensive. Drop in ready price shipped to your door with CMI e-top type headers are 24k.

The nice thing about them is the service life. The Air boat guys have been using them and beating the **** out of them. Seems the top ends last about 1300-1500 hours and then close to 2800-3000 is rebuild time.

Nice! I was hoping someone would pick up that line of LS marine engines. Indmar was marketing them six or seen years ago but when i talked to them about re powering the Batboat race fleet they were in the beginning process of switching their line over to Fords Coyote platform. Wonder how their pricing is, when i talked to them a drop in ready version of the CTS-V engine was in the high teens with rshaust . . . and a warranty in the race boats . . . thought that was pretty good

I wonder if that's a standard automotive crate motor with marine accessories bolted on ? Looks like the crate motor sells for a little over 12k without electronics.

correct but they have a marine version and a car version. I haven’t been able to find out the difference other then valves. The one thing I haven’t checked is if you can purchase the marine version from a GM performance dealer.

I was told marine power will be coming out with the LT4 SC direct injected version soon. The guy I talked with said GM is doing the cert testing for them this summer. Should be around 650ish HP

but they want $24,000 for the 550, hate to see how much the LT4 would be.

Another question is what kind of buss system to they have.

true. And that was with everything drop in, just add tails. I do like the service intervals. That and I would gain 6” between my motors.
