There are ways to soften a nitrous hit...Very nice! I’m planning on running Caltrac’s and also hoping to run a 300 series rear tire. Turbo power also isn’t nearly as violent as dumping a clutch or a nitrous shot, it’s very linear which makes the power more controllable.
1991 is first year for the 4L80E. 1990 454SS trucks had the TH400 (3L80 in "modern" nomenclature)If you're keeping the 4L80, just stay with the 24X stuff and do a 411 swap or aftermarket GenIII controller. To me, the appeal of GenIV is the 6L80/90 and the variable cam timing.
Not until the 4L80 came out in 92. Prior it was a TH400.
Would a 1991 350 rcsb have a 4L80E ? Thanks1991 is first year for the 4L80E. 1990 454SS trucks had the TH400 (3L80 in "modern" nomenclature)
I'm wondering about the 454SS rear axle OP got. If it came from a 1990 model it's got 3.73 gears to match the non-OD TH400; if it's from 1992-1993 it has 4.10's to match the 4L80E
Cool project!

Probably not unless it's a 2500 or 3500. The 1500s customarily got the 4L60/60E, depends on the year.Would a 1991 350 rcsb have a 4L80E ? Thanks

Exactly. Wouldn't get a 4L80E unless it was a 2500 (8 lug, not 6) or a 3500.. the only exception would be a 1991-1993 454SS.Probably not unless it's a 2500 or 3500. The 1500s customarily got the 4L60/60E, depends on the year.
That's what I thought! Pinger's Burb is very similar to mine except for the extra 3 lug nuts and the better transmission ( his is a pewter 99 C2500 and mine is a C1500, but both are 5.7s).Exactly.

The 'Burb really needs the 14 bolt, 4L80E, and honestly the 454 too.. JMHOThat's what I thought! Pinger's Burb is very similar to mine except for the extra 3 lug nuts and the better transmission ( his is a pewter 99 C2500 and mine is a C1500, but both are 5.7s).
The trans difference and the better brakes/rear axle are the main reasons if I get a 400 pickup, I'd rather it be a 2500/3500. Half ton is okay for a Burb, but the pickup has too many weak points.
