Keep the Ferd  Anything will run good with the right combo.... BBC vs BBF, they're both about the same

 In my uneducated opinion, the mod motor would be way cool.  I know there making lots of power out of those things and big turbos.

 If it was me though, I would start with the 460 you already have.  Get a new set of heads (bigger chambers), add a pair of turbos, and run the E85.  If you stick to that 800hp goal, and build it right, a pressurized 460 will last forever at that hp. 

BBF all the way!!!!! You can pick up a stroker kit for cheap!

Go big or go home!

I would not say that money is no object, as the more it costs the longer this whole build is going to take. But i think I really like the idea of the mod motor or the lsx for the cool factor. But all the of the engines are capable of the hp i want in a relatively mild mannered combo.

I like the idea of the lsx or the mod motor because of the weight savings, but i also am a ford man. But i want to keep things simple, and if i can save a few hundred pounds off the ass end of the boat i think it would be great! I already have a 460 ford, DOVE A heads, tunnel ram and carbs dist etc. just needs rebuilt. The boat is going to be down for quite a while so i can parts pick. Just noticed i said 3 engines, but i threw the bbc in there just for shits and now i cant edit the title, or i do not know how 

Obviously I would vote for the Ford, but I would first like to know what you are shooting for: desired hp, intended peak operating rpm, impeller size, and max spending.

Aluminum heads will save you only about 35 pounds, or the equivalent of a typical car battery.

Not necessarily. He already has the Ford.  Further, if you look at it in" hp versus dollars spent," it's possible for the BBF to give the BBC a run for it's money.

LO,

Disclaimer....For me.   I have three BBC's sitting on the floor, I didn't take into account that he already had a hunk of FOMOCO..

I have been told by a pretty reliable source that every 100 pounds removed from the boat equates to approx. 30 HP..Just for general conversation.

If i was to run the bbf or bbc i would try to reach my numbers n/a. To my knowledge a complete ls1 is around 450lbs? and a bbf weighs how much?

With iron heads, figure close to 650#, same as a Chevy 454...You could save 60#'s or so with aluminum heads. 

Everything is up in the air as far as specs, i am just shooting for a 90-95mph boat on pump gas. The motor will be going in a 18ft southwind with a set back pump, ride plate etc.... blueprinted bottom.

My 18-ft S/W is has ported iron "smogger" D3VE's and it goes 85 mph gps, no set back pump, no shoe, no rideplate.

But it also porpoises at that speed.  Jack MClure once told me that he knew of a similar boat with the same setup that behaved the same as mine. He did a set back pump & rideplate and it did 92 mph but porpoised wildey.  Added trim tabs and it went 96 mph and rode smooth as glass.

If you want high 90's on pump gas then you should consider stroking it.  A 4.14" stroke 501 cubic inch engine with your D0VE heads and 32cc Diamond pistons would give you about 9.75:1 compression ratio and put the peak rpm where you would want it for a Berkeley A impeller.  501 stoker kits can be inexpensive.

 Money is no option, well this is my dream motor.

 dart billet bbc 800+ cubic inch block
 dart big cheif heads
 whipple 305 r screw charger with inter cooler
 mo-tech efi.
 Saw a very similar motor run on the dyno when I did mine, with carbs and no inter cooler it went well into the 2000 hp mark. watched it put out around a 1000 hp and torgue at 1200 rpm. f n crazy. The screw charger puts out around 30% more than a roots blower and takes a lot less maintenance to keep up. This will cost you around 50-60 K. That's all.
