Thread: Which 460 stroker kit can handle 800+ Horsepower

Tweet

Hi all, I have been debating about building the 390FE in my 1968 Galaxie XL 500. I want about 750+ HP and have talked to many builders and people on here and it is close to the breaking point for the cylinder walls on the FE. So I think I am going to go with a 460 Stroker, sorry fellow FE guys!
I want to build a Engine with a nice stroker kit, 6-71 or 8-71 supercharger, Kassee p-51 heads and a t-56 transmission. I am looking for about 800 hp and cannot find a stroker kit that can handle it.
So I need your help please let me know what you think, I am new to the 460's and know I want a supercharged engine. Help me guys!

Use a forged steel crank--4 bolt mains/studs/support system

any of them will work to make 800+ with one of those blowers

I have been unable to get any verification of an overszed rotor for a 6:71 blower

you'll need a good fuel system, ignition system, and exhaust system

Thanks Jerry,
I have seen some stroker kits with forged cranks, but they usually say "up to 500HP" or somewhere close to that, do you know of any exact kits that can be used?
Also, what block do you suggest, where can I get a 4-bolt 460 block out of, what were they mainly in, like f-350, bronco?

I'm not a Ford guy - but I appreciate this effort. 460 stroker (557CI) that pulls 700HP and 700 f/p torque!

I hear the SCAT kits are "Ford friendly", but really pricey..

Let us know what you decide!

they use a bbc chevy rod a Ior H beam rod any one with a 2000 arp bolt or better will do $430 and up . a scat crank forged 4340 $1059 and je pistons $704 would get the job done

750 hp from an FE Series will cost you way, way, WAY more than 750 hp from a 385 Series.

We have done in excess of 700 hp with Ford strokers using cast crankshafts, not that I recommend this for a first-timer's 429/460 engine build targeting 750 hp. Are you sure that you need so much power? Is this a street-driven vehicle or drag race only? Have you ever driven a 750 hp 385 Series stroker? The torque and broad broad range of power might surprise you. Are you inclined to stick with the stringent maintenance program that such an engine demands, and do you have all the maintenance tools (on-engine valve spring checker, leakdown tester, etc)? The engine you are describing might cost $9500 minimum and that's without any blower or requisite blower accessories.

I would recommend a SCAT stroke rotating assembly with a forged crankshaft, H-beam rods with the L19 rod bolt upgrade, and positons TBD since you have said little about the engine application (race gas okay or must this be a pump gas engine?), 4.3 or 4.5 stroke, depending on particulars.

Paul,
Here is what I am going for:
I want to build an engine to prepare for more horsepower later. What I mean is, I don't want to build a 500hp engine and 6 months later want more. I am wanting to build a stroker that can handle 1,000 but only throw 500-600hp at it for awhile, and when I get tired of it, I can simply change the pully on the suprecharger to get more boost. I don't see myself running more than 750-800 horsepower ever, but I want to be prepared for it. I am wanting this car to be a weekend worrior, I want to take it to car shows, and run it at the track maybe twice a year. I am not looking to drive it everyday at all, but I want to go with a supercharged engine, so I can have a moderate cam and low compression so I can drive it without boosting and it shouldn't be an extremly rough ride. I am going to get rid of my c-6 auto and use a T-56 so it will be more street friendly. I am not looking for a 9 sec ride, I want a car that is capable of low 11's maybe even 10's, but not be a brute to cruse to a car show.
I drove my uncles 500hp Dodge Demon a few weeks ago, and it just didn't do it for me. It has the 3 speed 727 torque flight, a 340 stroked to about 380, edelbrock heads and a great tune, it ran well but was rough to cruse in. The torque was ok but just didn't give me enough to enjoy.
As for the price, I know this engine is going to cost in the upwards of $15,000, but thats ok, this build will be over the next 3 years or so. I plan on doing most of the work on the car myself, but I plan on having the engine built by a reputable shop because of the power I want.

use a 2 bolt block and install aftermarket splayed 4 bolt caps

to make 800hp with a blower you won't need a stroker, but will want a steel crank
look into the heavy truck blocks and cranks(bigger crank noses)

Jerry,
The only reason I wanted to go with a stroker kit was because I was told that the bigger the CUI the lower your RPM would be for max HP. I was going to try to keep it under 6,500rpm.
What year block would be the best and what kind of truck, like an older f-350?

HD429 from a heavy truck---F600 etc they have steel crank and bigger nose

If you want the stroker, the I would recommend a SCAT 4.14 stroke kit with a forged crankshaft. The lesser stroke (compared to the 4.3 & 4.5 cranks) can play apart in keep compression ratio reasonable for your application and also provide greater crankshaft structural integrity due to the increased rod/main journal overlap.

Such a build can be successful with a 2-bolt block but good tune is paramount and boost should be limited. Poor tune and/or way to much boost may be hard on the main caps. If it were my engine it would be a 2-bolt block, but if it were a customer's build then 90% chance I would 4-bolt the block.

A 4.14 stroke and 0.030" over pistons makes a 501 and generating 4-figure horsepower with the right blown combo is a walk in the park.

I grew up a Mopar fanatic and can tell you that the stroked 460 will downright astonish you compared to the 340/360...even if the Ford is built unblown.
