1020 hp 820 torque at 6500 on the bot. 730 hp 640 torque off at 6500.  those are the two runs I posted. makes a little more at 6600. pretty good for a 468. 11.5 af-12.5 af

  nice, is it EFI or mechanical? It looked like a 80a belt driven pump but it also looked like a EFI fuel rail. If mech. how drivable is it going to be? Looks awsome great numbers where did you dyno it? Keep us posted on the install! "D"

Thanks first off thank you. It is a FAST EFI XFI running on full sequincial. then  the pump is a vacume pump by morosso. Its recemended for high boost motors with a lot of blow by. nitrous = boost by the way. Instead of oil being pushed out of the valve covers air is being sucked in. it also inshures proper ring seal and i picked up 20 hp and a better idle with it. The block is a 4 bolt 454 60 over. steel crank 1010 grind. h beam cromolly rods and probe 12-1 forged pistons. it is a standerd stroke. The low end is pretty basic. Wish I went with the 540 but had most of it. The heads are the RHS 360 cc ported with all the best internals and shaft mount rockers. The cam is a custom grind from speed o motive. Im not shure of the the duration cause im in my office rite now but i think its a 48 at 50 thou and a 707 lift. The intake has a lot of work into it. Its a weind hi ram machined for injector bungs and a blower riser where the nitrous injectors are located.. On top of that is a bug catcher used as the throdle body. the fuel rails are custom made to for two cilinders a piece and the fuel lines are criss crossed. we did this so there would be full fuel pressure at all injectors at all times. The injecters are 72 pound. The nitrous system is from NX It is a dry system meaning it only injects nitrous in the motor not fuel. The ECU is programed so when the nitrous is triggerd the fuel injectors add more fuel. It is also programed to come on and off at 90% throdle or 7000 rpm by a simple arming switch. It does have a seperate purge switch as well. Im shure I left some stuff out just ask if you have any questions. Sorry bout the spelling lol. JIMMY.

WOW!! :o :o :o  That much horse power in a quarter stringer boat? Let me know how that goes! I have been looking for a new boat cause I was told the quarter stringer boats were not ment to handle much more than 500 hp.

Taco'd "a person or people that show up with one lake lice and a family of 50 and cram 3 people at a time on it with no disregard to boating rules or ethics. Usualy crap in toilets and throw shit paper in trash cans. Hang out at the boat ramp like its a swimming hole. Have zero insurance on anything they own and dont give two shits less about your property."

You would be suprised at how strong some of those short stringer boats are, a lot of times the only reason some  boats have full stringers (with a few exeptions) is because they are a lighter lay up, most of the quarter 'stiffie boats are layed pretty heavy and have a lot more glass in the bottom, I'm sure there are some exeptions, but I have seen some pretty badass blown big block quarter stringers running around with little or no problems.

Just my opinion though...
