Hey there Spilman!:seeya: I just found my way over here. This is my first 'serious' post!
The only LSM550 installation I am aware of is from that pokerrunboats outfit in the EU. They installed one in a 271 Fastech which, IMO, is probably not the best application since the CG will be effected quite a bit and it is a HEAVY 27 footer. I think we will have to wait until spring for a performance report on that rig.
It really does surprise me though that Raylar, after putting so much R&D time and money into developing this marinized LS engine, has not spent the money to install these in a boat for test reports and promotion in magazines.:huh: Boats already designed to have twin small blocks (like ours!

) would be perfect candidates. Until actual performance gains and durability are demonstrated, it's going to be hard to justify the $$'s. Until then we can just dream and :drool5:!
