Does Ford Still Produce The 515ci 625HP Crate Engine ?

[FUNFER2]

Late model, cool. I got my start in racing with a neighbor at age 13. He had what is called today, a outlaw late model. Is that what you have ?

Ah,....a Kirkham, the best on the planet !
What a time that would have been,.....you lucky sh*t. lol.....
They picked the best there is for custom engines.
What it the small or big block ?
Any pics ?

Why do you prefer a solid roller in the 460 ?

For this engine, what specs with the cam, would be the best for the street ?

Which brand of lifters and why ?

600lbs @ 3,000 rpm, is nuts !
Now that equates to.......fun !

That's part, of what makes sprint car racing so fun. 700 to 1,000 HP in such a light weight car.
With no weight on the back of the crank, the engine spools instantly, and you better be ready for it,. lol

How many cars can pull a wheelie from 10 mph to 100 mph !
Talking about knowing throttle control/wheel speed, you better in a sprint car.
Our aluminum 410ci motor put out 840 HP. Our 360ci was 720 HP.

My best friend Chad and I, raced sprint cars and he has a shop with a chassis dyno, and would test and tune our car and other teams on it. The sprint car system that you can add, is thousands of dollars , so it's not worth it.

Check this out. We push the car on the street & fired it up, take it out of gear, set it on the dyno rollers, and strap it down. We use a Honda 125cc bike against the right rear tire to get it spinning. At about,....2,000 rpm, the driver slips it into gear and the motor fires up.

The first time we dynod the sprint, when Chad stabbed the thottle it pulled a big wheeie. Scared the hell out if him. lol

What happened, was the rear shocks squatted down, putting a lot of slack in the two rear tie down straps, so after that we made two aluminum tubes with heim joints that we replace the shocks with, so it won't squat anymore.

Anyway, I need to look at the engine measurment diagram that is posted, but do you know size difference between the FE and the 460 ?
Also, is there a difference in length ?

I'm asking because I need the total length of the engine with the bell housing and tranny attached vs with a FE.

I'm hoping,.....I won't need to make a new hood scoop, meaning body work and repainting !
I painted the white stripes with custom mixed pearl, so I'd need to repaint the hood and the nose stripes. A lot of time and expense.

The specs. But, no water passages between the cylinder bores, is that ok on the street ?
I know very little about the 460 block & heads.

Ford Performance 460 Siamese Bore Engine Block. Thicker, reinforced casting, 4-bolt main caps, and no water passages all increase the strength of this cast iron block. This block can be bored and stroked to 598 cubic inches, ready to put out all the horsepower you could want.

460 Engine Block M-6010-A460 Features:
- Cast Iron block material
- 10.322" nominal deck height
- 600+ CID capacity
- Siamese cylinder design
- 4.360-4.625" cylinder bore range
- Wet oil sump design
- 3.000" crankshaft journal diameter
- Four on 2,3,4 main cap bolts
- Nodular iron bearing capmaterial
- 4.500" recommended max. stroke
- 1500 recommended max. HP @ 8000 RPM
- Two piece rear crankshaft seal type
- Std cam bearing design
- Block oil filter mount
- Can be bored/stroked to produce 600 cu. in.
- Weighs approximately 290 lbs
- Circle track and drag racing

You have a few options on the cubic inch with the aftermarket block. For heavier cars or trucks we typically do a 4.500" stroke which is 572ci with the 4.500" bore or a 596ci with a 4.600" bore. With the engine going in a Cobra I might recommend sticking with the 4.300" stroke and 4.600" bore which is 572ci. This will tone down that low end a little. Depending on the rpm you want to turn we could do a hyd or solid roller. Because of the valve train weight we typically only use a hyd roller to about 6000rpm or so on the BBF, if you want to turn more rpm you will probably want to run the solid if you are ok with adjusting valves periodically. Not sure what your budget is but most of my guys using the 460 in the Cobra are using the C&C motorsports aluminum block, but we can build it anyway you like. I have had no issues with the Siamesed A-460 block in street applications.

Thanks

Lance, when's the best time to contact you ?


So, 572 cubes

4.300" stroke

4.600" bore

I don't see, that I'll go over 6,000 RPM.

I was very surprised that with my 500 HP/550 TQ 428FE when launching in my Cobra, how fast 6,000 RPM came up, even when shifting the top four gears. Now, I was loosing some traction, but still surprised me.

What valve train do you like with the Ford big block heads ?

I fully expect,.... your motor to climb to 20,000 RPM,..... like a F-1 motor

What cam spec's in both hydro and solid would you suggest, including lobe sep ? (Itend to like 110 to 108 on higher lift's with low weight cars)

I like BIG,...cams, but I know it all has to work together, of course.

F-1 motor on dyno. (Insane)
