Could the new 640 hp zr1 motor be marinized? Would this be a good marine motor?

Don't know about the ZR!
but, this is in the works.

it's only 540 hp .
why the trouble for a super charge motor with such litle power ?

rayalr small block is 550 hp and no charger

only 540 hp it's a stock small block ?? was not very long ago it would been 270 I think it's a marvel for that power from that cu in at that rpm and not be a "race" type engine....

Why not lower the compression of the raylar and put a whipple on it. Raylar is that possible?
How much $ for the gm mtor?

I heard those are going to replace the 496.

What is the difference between the ZR1 motor and the LSA 6.2
Marine other than HP and TQ?

the zr1 revs much higher I believe....to hight for most drive to handle long term...

I agree. I think the Raylar setup is much better. More common parts used.

I'm sure the raylar 550 is a great engine, but not really a fair comparison cost wise. Just based on what they sell the LS3 6.2 for, I would venture to say the raylar 550 will be twice the cost.

I like the LS3 6.2, but haven't seen it in a boat yet. How hard would it be to do that conversion?
