Those are some really nice LS builds , That Phantom Bor you have is beautiful !
I was think Lt1 with Opti the mid 90's motor juste because so many of them are available around here and marine headers are available for them. I just cannot afford 3-4000$ headers for the LS heads. I am considering fabbing a set of LS headers but it looks like a challenge.
If I do the LT1 they are plenty strong blocks , the torque curves and hp resembles closely an old Big block power and torque but weigh less and cost nothing ... plus as a benefit EFI and my close friend know's those things inside out from building a bunch of turbo Lt's over the years.

I have this one build for my 21 phantom and gonna build a clone of it to put in my new cat 
on bravo its xr drives
I love it really strong engine if build right when I start the build in 2009 it was hard to find marine parts but know there pretty much parts available to just bolt on .

there are nice headers made in australia for arround $1500 a set that even have a murch collector or lightning make them for just in the $2K range
but I see your point budget wise the lt1 is much cheaper .

Bor , I will look around for some cheaper headers but for Now I have access to a very low mileage LT1 with minor upgrades , the motor makes about 400hp in the car it's in. With a decent set of SBC headers in the boat I would probably remain near the same hp. The boat is a 24 Progression LD i/o that's fairly light. What do you think ?

Ram , I think it will do pretty well you should be close to the power that it made in the car depending on the exhaust that has been in the car as som egood headers will produce some power ,a marine exhaust make less hp due to the cooling of the exhaust temp .
should be a nice set up !!
