? for the 21' eliminator owners

[wet77]

I am working on the motor for my 21' eliminator jet, now I bought it with no motor and have never had it in the water yet so I do not know where my peak rpm's are at and what I should set the motor up for.
The pump is a berk JG with a ride plate, shoe, diverter and ( A) impeller.
The pump is tight with only 10 hours on it.
I am looking at intake,cam combos and am really getting confused, anyone have a good combo for a 454?
The motor is stock bore right now and has a cast 4" stroke crank
heads are large oval and I am going to switch valves to 2.19''/1.88'' stainless type.
Anyone guess with about 500hp what rpms I would be at?
Or better yet tell me your setup and I could reference off it?
I just need a starting point.:D

Can't help you with specifics, but it would help others who are more knowledgeable on jet boat performance to know if you boat is a 21' V-bottom, or a 21' Daytona tunnel.

Jer's JPC says 5412 with 500hp and a Berkeley A. The type of hull really doesn't make any difference when it comes to what RPM you will turn. 500hp will turn a Bekeley A the same rpm on pretty much any hull.

sorry its a tunnel hull:D
So if I go with a edelbrock intake which one would you guys recomend one that is idol to 5500rpm or a victor jr 3000-7500 in case I add horsepower???:confused:

I just had my pump freshened up, 468bbc, 871 blower, same pump specs as yours, estimating 650-700 hp. Took it out yesterday and spun between 5900-6000 rpm wit 6lbs of boost. GPS said 86 mph. Hope that helps. BTW, its for sale.
