STRAUB picks his cams using a dartboard....lol, but seriously his the man for a custom cam!

Can't wait to get mine for the p-51 headed 545.

Cheers, Bob

He's done several cams for my friends 500ci + bbf and all have been spot on and make such usable hp and tq, the biggest problem with a jetboat motor is making enough power in front of the power absorbing curve of the impeller your using. Straub really seems to have a great understanding of this. This motor will be turning a AA impeller but I'm installing a IS plate system 100-200 tune, this will be for those sundown hot laps on the river

Any hp guesses? I'm hoping for 650 under 6000rpm due to my hp absorbed by my Impeller peak tq before 4500 rpm

So this motor turned into a 557 build due to a prepped 4.440 bore block and no availability of the ford motor sports 4.3 crank with 2.5 rods so I will be updating shortly

Motor is back on track and finished thanks to Paul Kane for getting me a RARE internally balanced Ford motor sports 4.3 stroke 2.5 rod crank, crank has about 8 pieces of Mallory metal installed. Crank weighed 74lbs, not bad.
Using the ford motor sports 521 roller cam since I need the power band to be under 6000 rpm. Installing a ford motorsports (victor style) intake and running a AED 1000cfm/4150 carb (for mileage).

Whats the lift/dur on that 521 FMS cam?

I went with the Kaase/comp cams.
