460 buildup

[blazeracer]

OK, I'm pulling my motor on Sunday and the winter buildup will begin. I read an article a while back on a guy who built a 460 for his boat and had it dyno'd. I wrote down what was used on it and collecting parts has already begun. I want to say the motor dyno'd 536hp at 5,400 or something along that line with 500ft lbs of torque from 3,500 up. It was a very usable power band.

The dyno run was made with logs that the bolts run through (Got em) with no risers.
a Wieand Steath 8021 SCJ aluminum intake (Got it)
A Demon 850 (Got it, but mine's a marine Demon, his wasn't)
Kaase designed Ford racing M-6049-SCJA aluminum heads - http://www.jegs.com/i/Ford+Racing/397/M-6049-SCJA/10002/-1 (They're next)
Topped with 1.73 roller rockers - http://www.jegs.com/i/Comp+Cams/249/1045-16/10002/-1
Comp Cams CL34-247-4 cam and lifters kit - http://www.jegs.com/i/Comp+Cams/249/CL34-247-4/10002/-1
JE forged pistons w/ -28 cc dish weight matched- http://www.jegs.com/i/JE+Pistons/532/170879/10002/-1
Stock rods balanced on both the big end, little end, and over all.
Stock iron crank spin balanced, found a shop in Mesquite that does this.
A high volume/low pressure oil pump was added in place of a stock pump.
Stock 4 bolt block was torque plate bored, line honed on the mains, deck surfaced, and all the other standard stuff.
Everything was held together with high quality ARP bolts and approriate pushrods used as well as a true roller timing chain.
I'm going to drop a marine dizzy on also - http://www.summitracing.com/parts/MAA-YLM567EV/

PHR did a similar motor with P-51 heads, flat tops, bigger cam, automotive headers and a car Demon did 634hp.

Soooo, opinions, observations???

what kind of compression? i went with flat top pistions in mine and ran 10:5.1 compression, with this cam  http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=990&sb=2  and was very pleased with the results, it had a nasty idle and performed great, i had the procomp alumn heads that had 300cc intake runners $929 off ebay, tunnel ram with QTY 2 little holley 450's on it, last mohican or tahiti rat can tell ya how it ran, they both have rode in it, i built it so i can cruise around the lake or had the power if i wanted to light it up a little, it wasnt the fastest boat on the water but it'd make the chevys groan a little to keep up...lol

Would work on childs play!

I looked at Procomp heads and flat tops too. The Procomp have a 84cc chamber I think. The Ford heads have a 72cc chamber so going with dished piston will net a CR .25 over stock. Looked at that cam, WOW... That's a big one. I don't want a cam too wild on my motor. The spec sheet says you have to machine the heads, use srew srew in studs and guideplates and longer pushrods.

Think we can get Matt to admit he rode in a really fast Ford??

Cliff, there you go brotha...... Bolt on 150 horsepower, since your putting a scoop on it anyway..

tunnel ram with QTY 2 little holley 450's on it,

When I was stationed in Germany I had an 84 Camaro with a tunnel ram and Holley 450's. Those are awesome carbs. That car would eat up Mercedes on the Autobahn. Mechanical secondaries, no choke... I think they are the best carbs out there for running a pair. That's my .02

I thought you had hydraulic roller? Nice!

That is one nasty cam right there!!! And guys are telling me my cam is too big.. LOL... Must be Chevy guys wanting to hold my Ford back...

You're running one four barrel on top of a Victor?

 

[duanehydro]

Yup, and cj heads...

 

[duanehydro]

Fords LOVE  a bigger cam, if you listen to chevy builders, you will be under-cammed. I have a 600 lift solid in a 289.....for the street....

Sounds Good Duane  !! clap.gif

 

[blazeracer]

DUDE!! That is an awesome motor! I was going to go with a Victor and a lot people said it was no good for a boat. It wouldn't fit under my engine cover anyway. The Stealth just barely makes it. It's all good though. The motor buildup I'm doing used specific parts to hit 530hp. That's going to be my story and I'm sticking to it.

 

[blazeracer]

Here's a 460 buildup with the heads I'm using. 511hp and 546 foot pounds of torque on a stock bottom end with a 272 cam, 950 Demon topping an Edelbrock intake on pump gas. Pretty close to what I'm doing. I'm using 1.73 rockers instead of 1.7 on this motor.

http://www.carcraft.com/techarticles/ford_new_scj_heads/index.html

Heads are $1,600 a PAIR assembled from Jegs ready to bolt on.

 

[blazeracer]

Check out the power increase from D0VE heads to the Ford racing aluminum heads, and the cam upgrade. This sucker is gonna pull hard out of hole.

 

[blazeracer]

Nice numbers...

 

[blazeracer]

Ports that will finally match my intake. The second photo shows how my ports look now on the left, and what they will be in March on the right, which perfectly match the Stealth ports. Those are the gaskets I had to use when installing my current intake. Gasket match porting will net a few more ponies also, just to take out that tiny little lip there.

my little Ford... not the best quality but you can get the jest of it.
