I can't tell you that much about it other than what already did. It's some sort of "class" motor. Ask him the power to be sure, I'm working from memory and was busy with dyno and my 2 motors. Here is the builder link. http://www.besracing.com/

Eric,

What did you decide on for heads? How's the project coming and/or the boat running?

Frank

Jim V is working on the heads and I am building the short blocks. Should be ready soon.
Eddie

Awesome, cool!

Jimmy V is a great guy and really knows his heads .......

How do the titanium valves hold up in the marine application? Are you using them for both intake and exhaust?

My 1.90" Inconel exhaust valves are as heavy as my 2.4" SS intakes. Would love to lighten the weight but I always thought Titanium is for drag motors.

I have used Ti. valves in a pile of drag motors back in my drag racing days, they where incredibly light, but, tended to be hard on valve seats, they take INCREDIBLE amounts of heat and are lighter than Inconel, but, unless you are spinning the motor to insane rpm levels I wouldn't recommend them in a boat, unless its a drag boat and/or you have a bottomless bank account and alot of free time for maintainance.

Something else I have found out [first hand] is you DONT want to ever "backfire" the motor, as strong and light as those valves are you would be shocked at how fast they "tulip" if you burp the motor.

I guess what it comes down to is that [99% of the time] there are better ways to waste your money.

Just my Thoughts!

If I had the money I would buy a pair of these, with a 10:1 flat piston, hydraulic roller and fuel injection, OH YEAH!!!!!

You should be using a alloy valve seats on Ti valves, I use alloy on all my heads, if not the intake always on the exhaust.
