    Staying within the wallet is always a good thing. Living within your'e means a better thing. Ford, Chevrolet,Mopar and even a Studebaker, they will all run just feed them love and money. M

    I like the idea of my Aggressor full A impeller (equal to Berk 2-A) and the efficiency it offers at cruise speed however, I feel this hull would really come to life if I could spin this A-Aggressor at more RPM...like 6000. And to do that would take some 800 HP. So in a way...more RPM is needed for my heavy 21' boat.
    Damn Jets need a tranny!
    You don't need more rpm at the pump, you need more power at the pump in order to turn more rpm. 800hp is 800hp, and the pump dosen't care how it gets it, but the engine does care how it makes it. Getting that 800hp would be easier with a 600" engine than a 500" engine. You're not going to get a "reliable" 800hp with a 496, and it's not going to happen at 6000rpm. If you want 800hp at 6K, you need more cubic inches, either with displacement or forced induction, either way.

    IMO, when you're on a budget, it makes life easier if you don't try and accomplish a $5K goal all at once. The bottom of the boat can always wait, but as long as you're in the engine, do it once and be done with it. A 20' jet is a big boat and has a lot of wetted surface area, which equals drag. You can improve the bottom, but the only way to get any appreciable performance is going to be with more power. The shortest route to more power, especially in a reliable manner, is with cubic inches, not RPM.

I'm not saying a 468 can't be made to run, I have plenty of customers with them that make great power. I just have had to many customers build 489/496's that have been on budgets and don't want to turn the engine real hard and they have made really good power. I just had one with a stock Q-jet, factory GM aluminum intake and a set of 049' heads pure stock make 590#/ft at 3800 rpm with a 9.5 to set up on pump gas.

    I like bigger cubes and lower rpm to achieve the goal in these "budget" marine engines.
    This is by far the best value for your dollar invested. If you have to save a few more bucks, or can come up with it, you'll be happy you did in the long run. Your heads can be made to work just fine with that combo.

Put together 489 CID engine with your top half components based on a 6000 rpm max and you would have an easy 550HP/600#/ft combo that should give you hours of trouble free boating.
