Stroker recomendations??

[vp6799]

I'm building a new motor which will be running a vortech s-trim blower kit. I was originaly gonna keep it as a 306, but figured what the hell. Since it's all apart, I might as well go big.

By doing a search on here and other forums, I came up with going the 331 route due to me wanting a very streetable setup. I don't want to run into oil burning or bearing problems like i've read about with the 347 strokers.

My question is what company do you all recomend buying from?? I've found kits from DSS, CHP, and SCAT that seem reletivaly close component wise. I've read up's and down's about DSS and CHP, but can't find any info on SCAT. I am looking for a quality and dependable kit to use.

My combo will include: Holley Systemax intake, AFR 185 heads, vortech s-trim. I'm still up in the air on a cam to use also????

For what it's worth, I've read in many places that the oil consumption problem with 347 strokers is essentially solved. Some of the cheaper (eBay type kits) still may have this problem, but using one of the big companies like the ones you mentioned should allow you to avoid it.

A few things to think about:

I would get an aftermarket block...the stock block will have trouble staying together with a stroker and blower. That cost $$$.

If you plan on 'big' power and 'big' boost, consider the 331. The 331 piston has more material to it, which is more ideal for big boost.

A 347 would work just fine but I would recommend getting the 5.315" rod instead of the 5.4" rod. The latter has the wrist pin boss that intersects the oil ring. It is more likely to let oil blow-by occur later on down the road.

Either will work just fine, I would recommend the 331 from personal preference. Power numbers will be very similar either way, good luck

331 or 347

If you were gonna go NA ... I'd tell you to go for the cubes

Since you talk about Forced Induction .......

I gotta admit ... Things change with all that and I can see some good
points about going with the smaller cubes.

Some have run oem blocks for a long time and had no probs
but
Others have not been so lucky

I've seen so many preach about good tune and keeping things
sensible (boost) is the key to doing it with just an oem block

Good Luck

Yes it's an OEM block out of a 98 exploder. I will be using that for the build. I don't plan on running the blower at max psi. I have read about OEM blocks not taking power well, but i'm not the beat the hell out my car person. I do plan on getting a good tune and will be picking up either a tweeker or a PMS system.

So I guess I should stay with a 331 stroker instead of the 347 due to the blower. Would I be better off going 306 and the blower, or 331 and blower??? I know more cubes is better to some, but I want reliability.

Most of the 347 downside myths have been debunked. Dont let any of that BS stop you from going that route. I went the 331 route basically just cause its different, seems like everyones running around with a 347 these days..

Like said above, power #'s will be similiar with either size motor..

Hey man, where abouts in mass are you located, and do you have any pics of your build??

I do believe that I will go with a 331. Now I have to figure out what company to deal with. I'm leaning towards CHP because i've heard some horror stories from DSS lately.

306 will make less power but be safer towards the block for that very reason.

Many are doing the rebuilt 302 with h/c/i and blower route with good results...

You start upping the cubes you start cracking the stock blocks If you really are stuck with a stock style block, atleast get a girdle so you can save some parts when/if the block cracks.

I gotta tell you Vic ...........
I really don't see reliability issues with either 331 or 347 myself

I base that upon what you say here

Now ... when I said 331 for forced combos might be more desirable .....
I should have said if going for a good bit more power that the
typical OEM block based Street Car Combo.

I have often thought about a forced combo myself

So ... when you see the amount of performance many have got from
an OEM block ... Well I see it as really amazing

So many say you can do 400 to 450 rwhp with not much of a concern
of splitting the block as long as you use good common sense like was
talked about above.

Now ... when talking about 331 or 347 ...........
You start to get into higher quality machine work and parts

Not necessarily so if talking about a 306 ... don't ya know

Having said all that ............

Here is a thought

You could do a nice bore clean up on your existing motor for
a dandy little 306
and
The money you would have spent on machine work and fancy parts

Put it toward a PMS, SCT, or Tweecer with Wide Band
cause
I can tell you this my friend ... Self Tuning ... It ain't cheap

About 1/3th of all the money invested on a H/C/I will go towards fuel support mods + tunning, but hey look it optimistic once you are there you can do whatever you want with your stang. Changing latter parts is just a little wrenching and some time on a laptop.

Im in saugus, about 10-15 minutes north of boston.. Where you at?

Heres a few pics...

Prior to engine bay painting and jet hot coating on the turbo system..

New motor mocked up..

And where im at now, i need to put the tranny in this weekend to finish up all the engine bay stuff since i need the motor to be level..

I'm in Fall River, about 30 min south of boston. That's a sweet setup you got there. Good luck with it.

I have decided to go with a 306 and the blower. Can't wait for the tunning part...

I am thinking about the tweecer rt system, what's the pms system and how is it compared to the tweecer?? Also is the sct a tunner like those or a chip??

Thanks

I don't know a whole lot about the PMS other than it is more easy to
use than the Tweecer

Heck ... Everything else is easier than the Tweecer

We have several PMS users here and maybe they will give some
details for you.

Yes ... SCT is a self tuning option like the PMS and Tweecer. For our cars,
I believe the particular one used is called the Pro Racer.

You can look elsewhere in the tuning forum because I know Don has given
a few details about it or look for posts by the member name of
Don 95Vert and use the link in his sig to go to his site.

Awesome, Thank you guys for the help and info.:SNSign:

So I take it the tweecer is a ****** to use huh.... I guess i'll look into the PMS and SCT systems. Never really heard info about SCT, so i'll look into it. I will search for that user name you said for info.

Now I just gotta contact either CHP or SCAT for pricing for the 306 stuff.

Thanks again
Vic
