    Is your jet done yet? If not, money will be worth spending in the jet department. For the engine, it all depends on what breaking the bank is in your world?

    You can build a nice stroker at reasonable price. If your thinking of rebuilding. Also finding out what heads you have on it also helps. But usually pistons, cam and some nice massaged heads will wake it up. What type of exhaust are you running? what is your ending goal? How much are you willing to spend, makes the most difference.

    Since your having your pump done and adding a place diverter, that is a good start. You will pick up speed that way. If your 460 is stock, you are probably around 275 to 300HP. You can build a lot of HP with a 460 an keep it reliable. What are your HP goals? How fast do you want to go? How fast are you now? What kind of boat is it?

    Like cp562 said lots of whats,and for $2$$$? I do have a 460 .30 over with chet herbert cam(540/562) lift (285/295 duration) performer rpm w/830 holley dbl pump(4150)1.73 roller rockers,roller timmong chain,rewarder ceramic headers,msd w/ rev limiter,pump has a "B" impeller, dove heads that have been gone over,( all the motor work by impient1 tom) and ive missed other things.All this and bench dyno,around 450/500+-And the best gps was 68.something,and was NOT done with a $2000 budget.Think your budget needs a revision to do what you have stated. Good luck.Note: next spring my boat will be on the market as a FYI.

    Had a 460 in my old Hallet 19 bubble deck. It was punched to a 501 with an Eagle crank and rods, 9.6:1 compression, Edelbrock aluminum heads, Weiand Hi-Ram tunnel ram with two 600 holleys, Lunati Hydraulic flat tappet cam, Bassets, built pump by MPD with AB impeller, blueprinted bottom by Bennett. With just me in it, minimal fuel and crap in the boat it GPS'd at 78 MPH. The guy that bought it from me yanked the motor, ported the heads, bigger cam, more compression, bigger carbs, Nitrous, more pump work and supposedly now it pulls over 100. You can make Fords fly!!!

    Jetboat missed .30 over flat top or pop-up pistons and is probably running around 10 to 1 on pump gas. You will need to build some compression. You did state dome pistons. Also an important part, you will need a 10qt oil pan with a rear oil pick-up. Stock is 5qt w/ front pick-up. The pan could be the most important when adding HP for reliability. Adding used Bassetts, block & head (machine shop work), valves, roller rockers, studs, cam, lifters, indexed cam gear, push rods, roller timming chain, gaskets and new bearings. You have blown past the $2000.00. That is doing assembly & porting yourself. This should get you to 450 to 500HP. You need a budget check.

    What color was this boat, and does that guy that bought it frequent these boards?

    Nick -My old Hallet is white with red metal flake. The guy does frequent these boards and his handle is Mudpumper. I sold him the boat completely turn key and it ran hard but he wanted to go faster. i have not seen the boat since the day I sold it to him but a few friends have seen and ridden in it and they say it flat hauls the mail.

    As far as I am concerned you can have a very strong running boat in the low to mid 70s. There is always a lot of input on this subject, they always say you must compromize. A mid 70mph boat is a strong runner just about anywhere except the lower Colorado river. Most of the work you can do yourself to keep costs down. For example, I race comp jets in APBA, this is circle racing. At the last race a 78mph boat stole the show over mid to upper 90mph boats. With the BBF I would not run the D3 head and see if I could find a set of go C8, C9 or D0 heads at a junk yard. You can do some gasket match porting on intake and exhaust. Then take .030" - .040" off the surface, this will bring you into the 72cc rage. If you go with a set of 2.20" intake and 1.8" exhaust valves you will be in pritty good shape. Comp cams makes alot of good off the shelf Hyd cams, I have had very good luck with the 292H. As far as pistons go the TRW/Sealed Power 2404 20cc dish is not bad. This will let you run just about any pump gas you can get your hands on. We are now talking about a 530hp - 580hp engine that is pritty bullet proof. If you want any further help feel free to call any time.

    Good luck and be safe

    What the biggest you can make a "stock" 460 block?
    Can't you go .060" over and get a stroker crank to come up with 572 or something like that?
    How about offset grinding the rod journals and running a smaller big ended rod?? Wasn't there a popular set up like that too? BBC or 440 Mopar rods...I am just trying to jog my memory here...
    THANKS!!!!!
