Got kids?

Be my first guess, lol

I would agree. I would probably build the engine as a 383" stroker and freshen up the pump.

I would take an educated guess you are likely to find a B impeller in that pump, regardless of what the tag says, if it was set up as a SBC to begin with. That and/or the weight of the boat may account for the RPM differential you are talking about. 

Now, if you are convinced of going to a BB, going to a 454 would be far easier than a 460, however. Your driveline and bellhousing/rear plate (depending on 3 pt or 4 pt mounts) can be reused, as well as possibly the flywheel. you would have to replace and relocate the front plate or side mounts (again, depending on 3 pt or 4 pt mounts) and then play around with crankshaft centerlines and driveline angles.

Nordie changed his old boat over from 460 to 454 awhile back. Don't think he wants any part of doing THAT again.

I'm with Tony. Actually, I think our trucks are the same year, etc. HOWEVER, mine isn't nearly as tricked out or nice as his. Stock wheels, no lift, vinyl floors (I can simply hose it out after a trip). Trucks are trucks to me, not a statement. BUT, very happy with it!

But no major issues with it, 155k miles, I had to have the FICM (hadda get a definition also, Fuel Injection Control Module) replaced 2 summers ago, cost me $1600, and I had the front suspension rebuilt (4x4, and had an exteme intermittent shimmy issue at highway speeds, mostly when towing) THAT cost me $4 grand, but then find out I got ripped off because I got a letter from Ford addressing the VERY same issue 6 months later. They listed the EXACT problem I was experiencing, and that the solutions were due to improper tires, and/or improper tire pressure)

We're in a lawsuit with the dealer on the 4k. I'm the kinda guy you DON'T wanna do that to. I'll spend 10k over the 4k you ripped me off for, and in the end will cost you 20k+ for doing it even though I'll never see that money again.

But, I have no complaints with my '97 F350! Good truck! The mileage, cannot be beat! I can head to Vegas, from here in Phoenix, and drive THAT god awful road, set the cruise at 70, and up over hill, dale, curves, mountains, etc, A/C on MAX, the only guage that moves is the boost guage, and I've gotten 20MPG dong so trailering a boat. Did 23MPG trailering to Big River this past fathers day weekend, beleive it or not! My brothers FIL has a Dodge Cummins he drives to here from Iowa all the time and can't belive the mileage I get.

This thread is soo giving me thoughts that my wallet can't afford.   A 543 cu. in. Spectra sounds so much better than a 460 Ford.   

As usual Ray, I hold you at least partly responsible for this.  Good on ya!

LOL! I know, MRS GC blames me for a LOT, and I'll take that! Hell I get blamed for a LOT!!!

To be honest though, WHY would you be stroking and messing with the king of torque like the square bore 440 Mopar???

There is NO doubt, nor should there be any question, that Ford and GM were playing serious catch-up to Chrysler in the 60's and 70's as they were, off the showroom floor! GM did the COPO thing, Ford tried the Shelby GT500, etc. NOTHING caught them!

Ray

How do you figure out what size crm theses bad boys are? I cant find any numbers on them?

Lay a machinists rule across one of the throttle bores on the bottom and post that measurement. Somebody'll give you a good idea.......Crewcheif will probably know off the top of his head tho.....

Ray

There are shims involved in SBC/BBC starter installs Daniel, I'm sure you know this already.

Ray

I wouldn't be playing around with bowl stuffers and/or inducers without first tapping into the pump housing and the bowl for some real pressure readings. You need to have a baseline number before you start really threatening to explode the whole works. The bronze Impy is a good start, I'd be with SS going the route you seem to be going AND knowing this is an SST where the hull is NOT going to slow you down. Your  bowl upgrade is another good one on that JE/JF pump, but again, these are mods that need more information to know if they are going to be successful or not.  You can toss one in there and maybe gain a few MPH, but when the pump explodes, boat sinks..........you get the idea! 

Ray

Crewcheif is the Holley expert I call on with these things. But is that carb the one that came on the boat? If it is, it should be a marine 4160, and if it isn't, you need one if you kept the "Eiffel Tower" of engine covers on that thing, Sammy!    AT that point, I'd be shopping for an 850. 460's LOVE 850's like "Mongo Like Sherrif".

The idle mixture screws, run them in, back them out 1 1/4 turns, leave 'em be. Who idles anyway? The jets? Need solid plug readings to be sure, but typically, I find #86 in the primary and #92 in the secondary seem to work out very well more often than any other combination. This is on 750 carbs. Would need to step up a size or two on an 850.

You're about to become a parent, WHY are you trying to hurt yourself? 

Ray

Congrats on the new additions! 

Ray

I'll try stock piling for ya and deliver when I can afford it, and when we meet up.

Am I gonna get in trouble for this like the " Moonshiner's Channel" says?? 1 ton truck........means I can haul 2 tons of the stuff.......ain't Junior Johnson fast, but it chugs along..........hmmmmm I'm seeing profit here!

I'm betting on this. I don't think they sell it in the not so great state of CA.

Seriously? The ONE state that needs it??? 

Ray

Same here! Happy 4th to everyone! We're staying partying here, staying off the water! (well, not entirely, we'll be in the pool........)

Hey! That brings sumpin up! Who's a pool guy??? I gotta know this! People plan to party here tomorrow!

Thought I had a handle on this pool thing over the last couple years, but apparently, I'm wrong, and Leslie's is only interested in selling me worthless crap!

Saturday, shallow end started to look a little green (water tested fine, but I'm an idiot), so I swept it down good, shocked it with 4 bags (30,000 gallon), turned the pump on all day/night. Seemed fine later. Sunday morning, looked about the same, so I threw half a quart bottle of Copper Algeacide in as well as another 4 bags of shock and turned the pump on......again........left it run all night, Monday, looked better, took a sample to Leslie they sold me a half gallon of this "pool Bright" said put 2 cups in, and I did. But was at the shop most of the day...........yesterday..........looked just as bad......So today, this morning, well, looked like a septic tank in there! Noone other than me occasionally has been in it in 2 months.

So I got pissed off today and absolutely nuked it! I put in a full 5 gallon bucket of shock (43 lbs), a half gallon of copper algea killer, and a half gallon of this "pool brite" PH balance stuff. It's been running non-stop since 10 this morning, looking blue, starting to clear up (I can see the bottom kinda), but gotta go to the garage or out front to have a smoke because the chlorine fumes even on the patio burn my eyes............ I''d step in but I think it might eat my flesh at this point.........

What do I do now?
