stroker crank?

Sweet. I think a stroker crank would be perfect for a syty. Most are low reving torque builds which is what stroker motors are great for. If I were rich I'd build every SyTy owner a billet stroker crank for Christmas. Oh well it's the thought that counts. Right? :wink:

You don't have to buy everybody a kit :) Just get me one, ok? :p :D :p :D

Just spoke with the fellow over there.

crank is 3.75 stroke with 2.100 standard SBC rod journals
probe pistons
Scat 6" rods

Keep in mind these are billet ranks, not a steel forging. I think the cranks will be good but I would definately shy away from the rods/pistons for our application.

The cranks are going to be around $2150 alone and when fitted with some good rods/pistons it will be vertually bulletproof. They have to be made (not in stock)

I will be offering a kit like this with a 5.7" rod, and meaty custom je piston.

Cool so how much will your combo cost Mike :p
I kind of figured the rods and pistons would be the wrong setup for us but I was hoping the crank would be less. The one question the s-10 people had was the possiblity that its an odd fire crank? I doubt that is possible since you talked to them Mike but still wondering. This is good now I can start saving my money for this :eek:

Mike will make right for us I'm sure...it is NOT an Oddfire crank, once you see a few you can tell the difference pretty easily...look here to see the difference between a Oddfire and Evenfire crank....here is the Oddfire...
http://www.chitownsyty.com/tech/crank.jpg and here is the Evenfire http://www.chitownsyty.com/tech/Forged_evenfireCrank.jpg what you'll notice is that their are less journals on the Oddifre crank because the rods are mated two per journal....unlike the Evenfire....but a nice stroker Evenfire crank will still go a long way if you know what you're doing :wink:

Thanks Ryan, I noticed the pic and everything but whats in an add ain't what you get sometimes ya know. That was the only reason I wanted to make sure that way a bunch of people don't buy them and blame me that they didn't get the crank in the picture :eek:
This would be real cool though if there was actually a aftermaket crank we could get in a timely fashion.

so, would this fall into the same category (ie: vapourware) as the la billet cranks and such?

The guy who stroked my stock crank can also custom cut billet cranks - for real, not vapor. Lemme know if this other supplier falls through. For those interested in stroker evenfire motors I suggest waiting until Dennis can do some testing on my stock stroker. The crank guy was able to go to 3.70 stroke "safely" in his opinion and swears it will handle 700 horsepower all day long. Once the engine is together and on the engine dyno we *will* take it to 700 HP (in stages, with dissassembly in between runs to check for any signs of impending failure). ATD, the engine dyno stresses the motor more than any in-vehicle use and if there is a problem it will show up early. As I alluded to in some previous threads, there have been some modifications made to the crank, engine, and oiling system to protect the crank. This includes changing to internal balancing, modified oil passages, improved oil cooling, and of course proper machining and treating of the crank among other things.

I will let you know how the crank holds up. *If* it performs correctly (as we expect it to) PEP will make this available - the reworked stock crank costs less than half of the billet crank, in the $1000 range (with core swap). This is a significant savings if it works. And remember, the crank guy evaluated the crank first to determine if it was strokeable - if he said it wasn't we would have gone straight to the billet piece - and Dennis considers this place to be the best.

Although 700 HP is a lot of power, some peple willl want more. That wil require the billet crank and Bowtie block. And big dollars. *And* this is 700 stroked HP, so the torque curve will be *much* better than a stock stroke motor. We're not talking about a peaky engine here - this thing will *pull*.

If any local guys (or any others for that matter) are interested in observing the engine dyno work lemme know - we're talking early Spring most likely.

I wouldn't mind checking it out. Maybe we can have a dyno day or something. Now that you're having your crank stroked... err.... that sounded bad :-? what are you using for rods and pistons?

Having a stroker crank is only part of the cost. Rods and pistons are the next step. You don't have to switch to some one-off high dollar piston with stock length rods do you?

Just wondering what the rest of the combo is.

Pistons are JE/Wiseco. Rods are, um, a bit radical. Dennis wanted to play around a bit. There are several options which would use off the shelf parts if I remember correctly. I'll get some more details on what's possible.

Dyno day would be cool. There will also be some kind of "Opening Day" festivities when PEP moves to the new location, and again when the whole "Performane Park" officially opens. I'll keep you posted.

Well, I'm probably going to go ahead and order one of these cranks to see if they can come through in a timely manner as they claim. My gut feelings tell me they can't. If they can, I will try stocking some and offer them to syty peeps at a better price then if you called up strokerkits.com

A billet crank is pretty much a billet crank, unless you are talking knife edge, lightened cranks. Your scat, lae, crowe, bryant, etc are all going to be the same.

There are stock cranks which are making close to 700hp. i have yet to find a point at which they snap, but on the other hand I really dont want to.

It doesnt really make sense to have a stock block/billet crank/eagle rod/trw motor. If you are in the market for a billet crank you should be considering the bowtie block, carillo rods, JE pistons, etc. It doesnt make sense to do it half assed, b/c you will find your weak link sooner then later.

For those of you who care, in the near future I will be offering a plug in play distributorless ignition/engine management system for the oddfires. Although the FAST system has been working pretty well, this will be the proper way to set it up. individual coil packs, and a cam/crank pickup. The cost will also be considerably less then the FAST setup when all said and done. I think we have solved all the problems getting the oddfire to work, but we are working on making it affordable.

The one's my crank guy does are knife edged and lightened. And some other things as well. Dennis showed me one of his SBC cranks (going into a Sprint car motor) versus one of the usual aftermarket cranks and a stock crank. You can really see the difference as you step up, and the weight savings is considerable. The custom billet cranks are under $2500 if I remember correctly.

FWIW,

Well there definately is a huge difference, and with the difference comes the price.

Most companies list there regular billet cranks for $2250-$2550 and the lightweights are around $1000 more.

If he is selling a lightweight crank for so cheap, I dont know why he talked you in to modding a stock cast crank. You should have bought a regular billet crank, which he would probably sell for not much more then what you have in your stocker.

I can ask for a price quote on the custom lightweight billet crank.

FWIW, we sent him the stock crank for evaluation and he said he could stroke it and have it hold up to 700 HP. He's the guy who did the crank for the WFSLC (253 mph). Dennis is *extremely* fussy when it comes to machine work - nothing is ever good enough - and he called the crank a "work of art". The crank shop guys were also more than a little proud of their work. For under $1000, the savings is significant and Dennis thought it was worth taking the chance since we're trying it out on the engine dyno first.

Sure, I could have gone with the custom billet crank, Bowtie block, mega $$ build but Dennis wanted to see what he could do within a reasonable budget. So we will see...
