Stroker In High Boost

[BiggFoot]

You are welcome to PM me with what you want for it but I am betting it is 10-12K over what I would spend on a short block build, so out of my price range. I realize I could offset some of the cost by selling my engine but I have no clue what it would be worth. It's a stout sonny gun though.

I wanted to go the stroker route because it tends to bump the torque up considerably, at least that has been my observation.

When and if I finally get my dream engine, it will be the iron block LSX variety so lets hear it from supercharged section. I truly value your opinions.

There's a relatively simple answer.

When you're driving off boost, at lower rpm etc....do you feel your existing setup is actually lacking in torque ? If so then a larger motor is maybe the answer. Whether that comes from bore or stroke...really wont make a huge amount of difference. Bigger motor gonna make more, smaller less.
And at the top end, the blower is sort of going to dictate the outcome.

4" strokes are very common, so not really any concern.

After a lot of digging and reading I have about come to the conclusion for my boost application I will just stick with the standard 427 cui bore of 4.125 and stroke of 4.000

In the process of gathering bids. I want the Dragon Slayer crank, Diamond pistons, Oliver rods, ARP head and main studs, custom ground cam, and assorted other goodies.

All sounds perfectly reasonable, although I'd be inclined to get the CCW cranks from whoever.

Thought about it but even when talking to Callies, both cranks are rated for 2500 hp and there is only 3 lbs difference between the Slayer and CCW. The Slayer will be fine for my little hp build. I am not about to join Street Outlaws anytime soon throwing flames out the side of my car, lol.

It's nothing to do with weight etc.

All those in favour of the CCW's simply say it runs smoother and gives the mains etc a much much easier life. I can only see positives really, as cost wise they arent that expensive for the more modest versions.

Their Compstar CCW is surely cheaper than the DS ? I think when I got my DS many years ago it was considerably more expensive, although those CCW's werent available then

so ST any complaints about your DS? I cant imagine there is enough difference between the two such that you could actually feel the car run more smoothly, especially since mine is shaking the whole car due to the cam lope, lol.

It has nothing whatsoever to do with what you might feel in the seat.

It has everything to do with how everything behaves inside the engine, and it's longevity.

If you can do something to help that, for no real extra cost....it has to be worth it.

I may do a bit more investigation before deciding. I wish there was proof that the ccw technology is better but more than likely to this point it is just speculation, otherwise they would stop making the other type of balanced cranks.

[stevieturbo]

It's not new, it's not unproven, it's simple physics too. The only thing that has changed is that instead of only super dooper billet $4k+ cranks using the CCW design, the makers have started making budget versions.

And as blocks need machined to accept some of the CCW cranks...not everyone is going to choose that route.

Callies do offer one that has some clearancing on the crank, but not sure if that will allow it to run in a typical LS block without some machining of the block.

Dart blocks will work with their crank without machining.

Of course if you already had a crank, then I would say just use it. But if starting from nothing, I'd be doing the CCW route, unless for whatever reason my chosen block could not be used with it.

Thompson Motorsports had a good price on the Callies Magnum CCW at $2200 which is only $400 more than the DS so what the heck, gonna give it a try.

[stevieturbo]

I was more referring to the dragonslayer range.

But the Magnum is certainly a step above that.

Or the Dart, although as said, I don't think it can fit regular LS blocks without machining.

Probably not a thing wrong with the Compstar but I understand they are forged overseas and put together in USA. Callies is USA all the way baby!

Next I have to find a good intake. Dont want a sheet metal one cause I hear they are noisy. Anyone have experience with the Frankenstein?
