S10 Xtreme LS3/T56 Build

[Dynamic]

Man, that looks amazing! Very nice job! My truck is clean, but not THAT clean. Awesome!



I know... I keep going back and forth between swapping to the T-56, or just building a nice 4L60E for it with a good converter and calling it a day. It is really a wash for me as far as cost. I own a custom transmission shop, and build automatic transmissions for a living, so the 60E would definitely be the easy way to go. It would cost me just about the same to build a 60 that will handle the 600(ish) hp that this engine will make as it would to buy a T-56 Magnum (I agree with you...the Magnum is the only way to go), bellhousing, flywheel, clutch, hydraulics, etc. Since this is already an automatic 4.3 truck, I'll probably just build a 60 for it and take the easy route.

I have to ask, though. Where did you get that instrument cluster built? This engine is built to turn some R's, and the 6K tach is just not going to cut it. And the 100 MPH speedo is silly as well. Did you send it out?

Did you have any trouble running the 58X Gen 4 engine with the 0411 ECM? That is one question that I still have unanswered. The truck already has the 0411, and a nice place to mount it. It would be nice to be able to use it.
