wow 7k in a jet boat is a bit high. Race boat or lake boat? Whos pump is in the boat and its set up?
Do you really think that? Ha ha ha, jk7,000 RPM = BROKEN STOCK ROD.
7,000 RPM = BROKEN STOCK ROD.
I'd tell ya what I'd do but I might get accused of spreading misinformation againOK SO MAYBE I SHOULD BUILD MY JET FIRST LOL GOOD INFO G CODE SO WHT SHOULD I DO WITH MY ENGINE TO RUN ATTHAT RANGE
Get someone who knows what they're doing port the heads and set them up for you ( bigger valves etc) . Get the best cam you can afford. I've heard good things here and on the other site about the Torker II intake for that RPM range.D3VE HEADS AND I HAVE ABOUT 2,500 BUCKS

We've done a lot of OEM block/head 460 jet boat engines, typically 450-600 hp for the OEM iron headed versions. You do not need to spin these engines to 7000 rpm in order to make 500 hp. Is there is a specific reason for the higher-than-usual rpm range?SO I'M LOOKING TO MAKE A SOMEWHAT OF A BUDGET BUILD 4 MY 18FT JETBOAT. I WOULD LIKE TO USE THE STOCK HEADS 4 NOW AND I WOULD LIKE TO KNOW WHAT IT WOULD TAKE TO GET A 460 TO SPIN 7000 RPM AND MAKE AROUND 500 HP ON PUMP GAS.
This is definately down the correct path here, lol.Get someone who knows what they're doing port the heads and set them up for you ( bigger valves etc) . Get the best cam you can afford. I've heard good things here and on the other site about the Torker II intake for that RPM range.
Approx 10:1 compression, ported heads around the 300+ cfm number at .550-.600 range a ported intake like the Torker II, the right cam and an 850 dp and you'll be in business.
Not sure on your budget what you'll be able to do
G-
I get lucky every now and thenThis is definately down the correct path here, lol.
