My fairly mild 454 is making 5,400RPM on that B.What sort of HP/RPM you getting with the B cut?
What's the base motor you're working with?Nice...So what you think I need for this one? 800? Thats my goal...blower motor if I can afford it, laughing gas if money is an issue...leaning towards the gas as you can tell by the name...
all I have now is a 454 4-bolt that I will be building up. I'm liking the idea of nitrous whe I need it/want it kinda thing.What's the base motor you're working with?
800 is a tall HP order without a blower at usable RPM, and if you get that much HP, IMO you really need an A cut on that Aggressor. That will hold you to about 6-grand. Arround 6300 to 6400 with my B.
The bigger the cubes, the easier it is to get that HP at a good RPM too.
Not nearly as tall an order to make that 800 ponies out of 572 cubes as it is to make out of 454 cubes.
I happen to like Nitrous, been running it in this 454 29 years now.
How often do you actually NEED the full engine HP? For me, rarely.
Build the motor for a solid 650HP or so and let it make the other 150 on a plate nitrous system. Much simpler build, MUCH less maintenance on it, less constant stress and wear on it.
My bronze is somewhere between an A & an AA. Its a heritage impeller (nice copy of a legend impeller). Im turning 5800 but some little tweaks have me thinking Ill be at 5900 or maybe even 6000 next time out.You got an A?
Thanks Ken I'll be sure to check when it gets here.If I were you I'd clean it up really good with a skotchbrite and check really closley for cracks. I bought a new one just like that, ran it for 3 mos. and found 3 cracks in it. (700 hp.) There were quite a few with casting flaws which were sold to the public.
Ya I was thinkin big inches either way. Whats the stroke/bore for the 540 so I know what to get? Thanks.My bronze is somewhere between an A & an AA.

Go with what smokin said, more cubes the better. With a 540 it has gotten pretty easy to do, as long as you do your research first.
