Performance Engine Build...

[Sharp shooter]

So Bruce, since this is basically a "nothing" thread so,,,, how about giving us the specs and parts on your hydro engine and if you're so inclined explain the advantages of running a 385 series Ford over comparable engines.

Thanks in advance!

No advantages of a FORD versus CHEBBY other than what a guy likes and is comfortable building IMHO... Availability of off the shelf parts is a draw for some folks but that has never been me, then again my project hasnt hit the water since I set the engine... There are design features on the BBC engines I Like and there are features on the BBF I like... Same for SBF/SBC...

As for my Sanger, the plan was/is to use my 429 SCJ as a starter engine to see if I needed/wanted MORE HP and go from there... The engine was in my 64 galaxie that I put together for drag strip action BUT the track closed so I ripped her apart... Standard bore 429CJ with work done on the heads/new valves/springs/shims/keepers/retainers, Comp Cam 294 / .605 lift solid flat tappet cam (the last I will EVER USE)... I didnt CC the heads and do a precise CR calculation but the factory specs are anywhere from 11:1 up to 11.7:1... Weiand Stealth intake and mildly worked over Holley 850... Factory ford Duraspark distributor / MSD box and that about sums it up... The bores are standard and could use an overbore, the crank is std/std...

My first post was total total total total BS right down to the bearing clearance numbers and anyone that knows anything about crank/bearing clearances knows even that part was terribly / stupidly wrong...

I started this thread on the heels of the assertions in the POLITICAL thread about "religion and war" most of which were blatantly FALSE. To many they would read my first post and say "Bruce said to OR I read somewhere to do this" (hopefully not) without knowing any better... It's kind of the same thing as I see it, in some areas of life people can say most anything they want and without a discerning eye from someone that knows or has studied (like GN7) the clearance numbers weren't even remotely close... It was funny to see Bob and a few others reaction to the total CRAP numbers about the crank/bearings which were a joke...

[QUOTE=2manymustangs;135145]Is that what works best in blown alcohol engines J.J.?


It's that top fuel shit, the way it should be. Drag boat K-boat stuff, LOL

I'm building a 460 Ford with stock E7TE heads. Do you think this engine will work with well my Comp Cams Xtreme energy XR294HR? I'm thinking the Holley 2 barrel off my old 78 mustang should top things off perfectly too.

Excellent choice in carbs, be sure to jet it super fat to keep that sweet top-end alive

thats a secret combo for a major bump in compression...

Whats that mill supposed to make?

@11.7 you better not plan on filling up on the water- anywhere.

When is coming out here so I can ride in it?

I run a 13/16 race cam

I'm going full race. Someone told me ProComp is a winner, or is it Speedmaster now?

with 73.5 cc combustion chambers and assuming a .045 thick head gasket and very minimal valve reliefs (flat tops with valve reliefs were stock on CJs). some of the later CJs had the piston down in the hole by a fair amount to drop the compression but my 1970 block/parts end up with nearly zero deck clearance. I think the actual CR is down closer to 11:1...

When you throw the small chamber CJ heads on a 460 you instantly go WAY up over 13:1, that is why all of the big stroker ford pistons are dished (inverted dome)...

I guess the question still stands- hows it gonna run? and whats it going to do in your boat?

So you got a non pump gas friendly mill.

Once you commit to race gas you can't just drop onto any ole place and fill up so that pretty much defines the boats role.

If you are going to run race gas then you can run 13:1 and over.

Love race gas toys. Id like to have one as a third boat someday.

I put about 50 hours on the engine just running 93 octane pump gas and it never did ping/knock HOWEVER it was pretty darn hard to load the engine with a four speed and 4:30 gears and 9" slicks... In the "water dyno" it should be easy to see if it will ping and bust up the 40+ year old TRW figure 8 slugs...


The boat had a 600" NA chebby the day I bought it and was so stupidly over powered for my taste that I didnt think it necessary to go crazy with a new engine right off the bat...


I got sentimental and bought the wrong boat, this belonged to THREE close friends of mine, two were high school buddies and the first died of cancer... What I really need is a 21' Raysoncraft hull like the GN47/GN24 that I can run at LOTO and on our big lakes... This is one reason I haven't hit the water, we dont really have too many good gathering places for Vdrives/hot boats around here and the lake I grew up on wouldn't allow this boat on the water... I've lost motivation, I need something with MUCHO more freeboard...
