Eric, the 30 I'm looking at runs 110mph on true 400hp small blocks, but I'm looking at 600hp LSD motors and bravos or arnesons. Should push mid 130's

They tested it with 390hp small blocks at 105 mph, before fine tuning, it might be the fastest 30 + pleasure cat, will check on weight

Could we get a name of the model and manufacture?

Big block better value...great torque and simple....

I know what it is now. Let me know how it works out, I will be getting one of them in a year or two.:coolcowboy:

Tell Arnaldo that Phil with the Kryptonite said hey.:party-smiley-004:

LS7 small blocks cant beat them the big block is dead for this size cat hp to weight better fuel consumption and same power and torque

Jim, I agree with you for these size cats the small blocks are a better power plant. Much lighter, less money, much small, and just as reliable. I'm sure they are more efficient as well. I have looked at so many recently, just trying to find the best value on a 600hp model. Right now I've looked at 3 or 4 nice fuel injected models in the 14k-18k price range. Did you build your own. Can you tell us the specs on yours and an approximate cost. I know you have been really happy with yours

A 30' AMT cat per the picture in a prior post in this thread. Those AMT cats were/are very good.


But JimKID's 30' Skater with his small blocks is definitely the sh*t, I really like that boat and set-up, a great size, power, and drive combo.

Light - yup check that box.

Just as reliable- well know in 10 years

More efficient - it take X fuel to make X HP not sure they are any more efficient per HP than big blocks- check a maybe

Cheaper - I dont know for sure that its less money.

I think you'll find that turnkey small blocks marinized in the 5-600H range to be 20K +

Ralyar LSM-550
Mast 600
ILmor LS series

Pretty sure all of these crack 20K when delivered ready to run.
