Engine builders....cam suggestions
 
Trying to help my old man out and figured I would ask the brain trust...he is getting a motor together for his jet boat and he's not looking to break any speed records just has some wants so figured I'd see what you guys thought....

460 ford(yeah I know lol)
Not a huge ford researcher so he said he's getting "the good" ford heads...apparently they have some castings that are pretty good from the factory I guess
Stock bottom end with all new bearings and seals of course
2x4 tunnel ram and will be running my Holley 2x4 EFI setup that I just took off my boat with ignition control
Full dry exhaust over the transom
He wants to stay hydraulic roller and wants to go as big as he can since he's running dry exhaust

Again not worried about ringing every single HP out of it just wants it to sound as mean as possible and whatever power he gets, he gets lol

It's a 19-20 ft beisemeyer jet boat that he will just be tooling around in annoying people on inland lakes more than likely hahaha

Thanks for the help!

What rpm do you need to need? What does your jet impeller hp chart look like?

What is your intended cruise rpm?

Jones Cams has a good Marine Cam Selection questionaire for him to give you a cam recommendation.


BBYSTWY 10-24-2025 01:21 AM

Based on the 8.5:1 compression and iron heads he's not looking for huge RPM numbers....I would guess cruise around 3-3500 at best and 4800-5000 all in. I have zero experience with berkley jets but I do know it has the standard A impeller which means something to someone I'm sure lol.

He's basically looking for mid range to upper mid range torque and something that's very "grumpy" sounding at idle lol

go with a 3/4 race cam with really big bumps in all the right places!
