Ok I know I'm not a Cali guy... But did drive to jetboat performance to pick up my little bubble deck... And have been on SoCal jetboat for years now... Lots of good info here! And helpful people! So I'll give a little run down of what I have going on here and see if maybe we can do some hp and trq numbe guesses?
Started with a blueprint 632 tall deck block...

Also got a set of blueprint 358cc runner heads...
Got my arp stud kit and started putting the big pieces together...

Found me a nice set of scorpion rockers and got my comp cam push rods and got the long block bolted up...

Had Armando racing pans build me a sweet 10qt pan for it...

Then found me a dart tall deck intake

Sent it off to get powder coated after a couple of hours of hogging out the runners to match up with the heads...

Got everything mocked up... With valve covers and installed some new breathers

Got me a scoop from lifted250 and started building my scoop trey and support brackets

Took the scoop over to my buddies shop to start putting some color on it...

Then had to test fit it all to see how it was going to look? Well and make sure the pan was going to clear? 😎

Went back and forth a little on the carb? A little nudge from gt jets in the right direction and wound up with this jewel... Quick fuel 4500 series 1150 cfm... I know I know the 4500 is on a 4150 intake with an adapter.. Put this is a 10-1 pump gas deal... I was not chasing every single hp? And that's easy enough fixed at a later date

So got the valves all ran... Pan full of oil.. And loaded it in the back of the truck and took a trip to San Antonio tx...

Not going to lie? I didn't sleep real good that night just because I had NO idea what this puppy was gonna do? If my almost year of rounding up parts and doing the best research I could was going to pay off?? Or what?? The dyno guy didn't sound real impressed when I told him the numbers I was HOPING for? He was like (on pump gas) lol
We ran the motor on 93 octane with 35* of timing
Before we get to far here? We could not turn the motor past about 5900 rpm? The dizzy I had in the motor I had put a msd rev limiter in it and had it set for my old 496? For some reason it would not reset any higher? We tried a stock hei but not enough fire in the wire! Lol but I won't turn it no tighter than that in the boat anyway! Just a good solid lake boat

So? Any guesses? Hp and torque numbers? Remember it is a single carb 10-1 pump gas deal

That deal should run like it stole something.

812 hp. 780 ft lbs. That's a huge lift on the cam for only 5900 RPM's.

I'm really curious to see how that hull handles the power that thing is gonna make. (I have the same). Killer build this far👍🏼

The previous owner had a blown injected 540 on alcohol in the boat... I think the hull will be fine handling the power...

I think we prob left a little on the table not being able to take it past 5900rpms? But don't know if I need to chase the hp when it's making that kind of torque down low?

Depending on what's been done to your pump, I doubt seriously you left anything on the table, if were in a big bodied Chevelle with a Powerglide I would keep digging. In your jet, this thing will be "all in" at 5,500rpm.
Just my personal opinion based on past experience.
Thing should rock pretty good.

Thanks for all the replies guys!! I'm with you gt! Gonna set the pump up to turn about 5500 to 5700 rpms and let er eat!! 😎

Well finally got the pump all set up and got the new mill set into the boat and wired and plumed... Finally got to hear it make noise for the first time in the boat... Still need to put it on the hose and set the timing and dial in the carb but it's alive! 😎👍🏻

I cut the race mufflers off of those upswepts and welded some I think good looking collectors on them... Now just have to get them coated...

It's the blueprint head that they sell for their 632 crate motor... Throttle response sounds awesome! I can't wait to get this thing in the water and kick the chit out of it! 😎
