That isn't accurate. Get better track width numbers and you'll answer your own question. The rears are narrower than the fronts by about 2 1/4". You can visually see it on a factory S10 4X4.

There’s very little happening in the SyTy community in the way of groundbreaking performance builds. Those who are pushing the envelope and using BW twin scroll turbos in the Buick world are building mostly 7 and 8 second street cars. There’s literally nobody here doing that. A handful of...

$28k? I know what the health reason is... he's nuts.

Thanks Mike. I found one elsewhere. This part must be cursed.

Never got an email on Jeep Shaft. Is it pending to me or somebody else?

PM'd also yesterday, but I'll take the Jeep Shaft. Shipping 06093.

Yeah supposedly according to the article in GMHTP, Ed was running 11.5:1 but that was on a Bowtie with a Solid Roller Cam tuned specifically for 118 octane gas. Not a real relevant data point though for real life. His solid roller was also super secret squirrel so you don't know what his...

Is this a Bowtie build or a stock block build? If he's working on the heads you might want to circle back and confirm the compression ratio before he does something like deck the heads. Just shoot for 9:1 unless you're planning on something exotic.

Compression ratio alone isn't everything - overall cylinder pressure is a factor of compression ratio, your cam, and finally boost. Your fueling then becomes a balance of that overall cylinder pressure and octane. Factory compression ratio is 8.35:1. A more peppy compression ratio is 9:1 or...

While low boost can be a theoretical failure mode it's very rarely the case without other symptoms (smoke, noise, etc). Exhaust manifold leaks? Intake manifold leaks? Do you have a wideband O2, what sort of numbers are you seeing? Whats the cat situation? With nothing obvious on the table...

Totally agree, and I know a guy that used to run a forum much larger than this one that would help.

Depends where you're at. Somebody had listed one in Utah (?) a few months ago. EDIT: Found it. http://www.syty.net/forums/forum/marketplace/members-marketplace/parts-for-sale/1859074-ut-899-virgin-bow-tie-block

Use 100k+50k resistors and a 100k potentiometer to find out exactly, but I suspect it's 200k. Unless you're talking about an LS1 - in which case it seems most people just change the LS1 ecu output to output for a V6 tach instead.

It's a thought - but I can't see how the signal being messed up would show different MPH when the ground is impacted by different things being plugged into the cigarette lighter. I'm thinking more like poor ground circuit is gaining voltage +1V +2V, etc which is modifying the readout because...

Any update?

The 4WD STrucks have the ball joint on the pitman arm instead of the center link, the 2WD STrucks have the ball joint on the center link instead of the pitman arm. The pitman arm on a 2WD STruck isn't something that needs to be replaced since there's nothing on it to wear out. If you've got...

I wouldn't call it a coincidence - there was a significant amount of re-wiring that went on to install the FAST and there's a good chance that something got messed up or missed in that rewiring. The speedo only has three inputs. There's a Ground. (Let's check that first) There's a 5V...

Your Speedo ground comes from a black cable that goes through the C100 connector that goes to the front drivers side intake bolt. It's shared with all the other things you mentioned. Location is C2 in the C100 Connector. I'd start with making sure that's there. Is this a Classic FAST or an...

Are you saying that the Speedometer is reading 30/20/10 or are you saying that the Speedometer is reading correctly but the FAST is reading 30/20/10?

SOLD SOLD SOLD These are STD size (4.000") forged pistons, qty 6, pulled from '93 Typhoon 0823 which was a Rockford Racecraft build. I don't know the exact mileage but under 10k. Part number L2441F, sold as both TRW and SpeedPro. They're ceramic coated, mostly still there though it flaked in a...
