WOT rpm for a carb'ed 1994 Pro Boss HO

[petteralexanderson]

Hi,

I am trying to find the correct propeller for my 1994 SN, with a carb'ed 1994 Pro Boss HO. What would you recommend regarding WOT rpm range? I have heard from 4800-5100 rpm, but have no reliable figures, and cannot find it in the manual.

I have a standard PCM 351 in my 1996 MB and it only turns 4400 at WOT with a 13x13 prop. I could probably drop to a 13x12.5 prop and pick up a little performance but it's already a very strong runner. I think these older Fords should ideally be at or below 4800 RPMs when properly propped. The power curve on these is lower than the newer GM motors.

In my old MC with a 351 HO, WOT was 4,600 rpm.
