I have stopped in Tyler's since he started these motors and watched him build them. The attention to detail is amazing as is the amount of time and resources Tyler puts into his engines. Now you can see why he sends engines around the world.

my point or question is could you run 10 plus compression with that motor(more like 11) and get away with it, using the alum. heads and 120 on the water temp?? and still just 93 pump


I was trying to make a safe package and not looking for every last HP. It takes 17-20 HP to get 1 MPH on the water and if I ran the compression up to 10.5 or 11to.1 we might have gained 35 or 40 HP and it is not taking the chance on burning pistons in this pleasure boat. The big advanage with higher comp is that it makes torque.

Do you do stress relief shaking and/or cryogenic freezing?

I have done some in the past on some gear sets. We have not done on any engine parts. We do coat the Pistons and pins and several other parts inside the engine. We also use piston oilers on some engines. These smallblocks have a hole EDM drilled the length of the rod so the wrist pin gets oiled from the rod bearing.

Default Headers?

[Hi Tyler

Are the exhaust ports on the SB2 head the same as a old school SBC or more like an 18 degree replicated port head?

If you were building this with a clean sheet of paper would you use this head?

The reason I ask is a really want to do a small block 30-32 cat very light with bravo's
Thanks
Steve

Wow! That's impressive. Are you considering a milder version as a standard offering with a little less cam and compression that can run on 89 octane and still make around 550+ HP? I know many of us that keep our boats in the water can't get premium fuel. A less aggressive cam and valve train would reduce maintenance and improve reliability for those of us looking for high performance alternatives to our boring 320 HP Merc 6.2's.

I had Inconel ex valves made to go in the heads also and used their Titainium intake valve. I used all their Jesel valve train also.
Now that Crane is gone do you know if Jesel is doing ok?

how would these engines do in a larger boat like a 37 OL WITH BRAVOS and would it last. and what would you think it would cost for a pair of these rigged in the boat just a good guess
