Another vote for the 4l80

I'm sure it's great, but from my understanding it's a tr6060 with some stage 2 parts in a t56 case.

In other words it's well suited for an S10. IIRC, the f body T56 places the shifter right where it should be in the truck, where the stock tr6060 requires mods to work.

It looks like cost is roughly the same between the 4l80 and a built T56/Magnum T56. I do prefer rowing my own gears, yet I've heard the 4l80 is near bullet proof and seems better suited to my build.

I wonder how the T56 would handle ~8psi boost and a small shot of nitrous? That'd be, say conservatively 500whp/450wtq.

There's a whole lot of people with 500 whp in T56 fbodies. I don't see a mildly built one having any issues.

That said, yes, the 4L80E is a tank. Absolutely no power concerns now or in the future if you went that route. But you'd also have more drivetrain loss of course.

Hmm...

I'm more concerned about the kind of drivetrain loss where I leave parts behind in the road.

even a stock T56 will last awhile under serious power. A good buddy of mine was knocking on the door of 800rwhp with a stock gto trans.

Still going to recommend the 4l80. It will get you on the road quicker as you'll need very little modification/cutting, which means you won't weaken the underlying structure of the truck. Body twist is a real ***** to fix
