Re: 357 SR1 Top Speed

Formula sent me the spec sheet and it says 61 mp/h at 5000 rpm with twin 454-420.

Re: 357 SR1 Top Speed

That's right where I'm at, so I guess I should not complain. I would consider upgrades but @ 20hp per 1 mph, I don't see it happening with out supercharging, and as I said before in this thread...no room with out ruining the hatch.

Plus the starboard drive moves slower than port drive really making it fun to adjust.

I am really considering changing the hatch and adding a couple of scoops. The Gaffrig flame arrestors are small and thin and I want to get more air in the motors. I am considering some large K&N Marine Filters on top of a stack in the scoops.

Steven ... what do the Gaffrigs look like ? I might be interested .... holley carb ?

I am on the road at the moment, but here is a pic. They are on 850 holleys by Nickerson Carbs. They sit very low on the carb and have a notch for the float adjuster screws.
