I love Tony. Really do. Have info on that. Someday we'll talk.

That said...... good head, over 500cid's, 10;1 compression (or more), and it is really hard to overcam a BBC.in terms of making big power #'s.

Now, overcamming in our I/O world, would be to have a cam continbue to make power way beyond where we are going to rev it.and/or idle rpm, and/or exhaust constraints, .and/or parts replacment periods.

Without those I/O non racing boating constraints, a 502 w/10:1 or so compression can make 700hp.

Good thing Bob recommended 325's and a horrible cam, no blood pressure raising I will be changing things at feeders H time and Bob is not on that list of helpers.

Just ran across this a little earlier. I'm not trying to raise your blood pressure but thought it was somewhat interesting. How accurate the info is I'm not sure.

Hey Joe how are those Bravo Threes going to like all that torque ? Send me some pics of the boat when it's done I would like to see the transformation. John

Agreed, calling for moderators to ban him until build thread is posted... Bravo 3 lowers are very strong, the uppers are the weak spot on these boats. Easy on, Easy off, drive showers, amsoil marine lube mixed with lucas oil snot. Lets see this boat!

Did you want a CNC'd head (315cc)? The CC' porting on the 315cc is about $1000 more expensive per set then the 325's.

If you wanted to spend the extra dough, I might have suggest you go with the 335 in case you expected to increase cubic inches in the future. As a cast head with a partially cnc bown, the 325 is a good head on a 540 IMHO. There's a bunch of others that are good too. Just depends what you're looking to get out of it.

Nooooo don't ban me��
I promise to post some pics when I'm done, literally working 12-14hr days until it's done!
Picked up second motor yesterday made almost exactly same power (+3hp) .....off to install

I wanted 700 ish hp, so I told bob to give me the heads and cam to do so, knowing I could not go dominator and used a 1050 4150 style carb he said easily 680+ I saw 630.... Bob failed at my combo. Looking back is seems a 315 head and 741 cam would have been the best choice for my goals.
