454 bolt in ?

Yes my carb with no lock up doesn't like anything above 60, 70 max

All you need IIRC to run a 4L80 with a carb is a TPS and tach signal to a TBI computer. Easy peasy Japanesey.

How would that setup on a holley carb ? Wouldn't you also need said tbi computer be tuned or flashed for a 4l80e ?

You just get one that came from a 4L80 to begin with. TPS sensors are easy enough to get for carbs.

Personal experience ? I'm just wondering have heard some mixed things

I've been around around a long time and seen a lot of failures. If I remember correctly @df2x4 smoked one behind a stock v6.

Nope, mine was a local builder. I've heard plenty of horror stories about Monster, though.

Gotcha. Fuzzy memory...

I'm certainly biased as I've had a 1/2 ton with a 454/TH400 setup and absolutely adored it. The 400 stood up to it's constant abuse and never missed a beat. I'd go for that if you haven't already bought the 700R4.

4l80e will handle abuse pretty much as well as the th400 and have OD though, definitely worth the extra effort.

Yeah but he's going carb'd with it so I'd imagine getting the TH400 to play nice with the engine would be a ton easier than trying to get a 4L80E to. I think TH400's go for much cheaper than 4L80E's as well.

I can't argue those two points, but I still think the 4l80e would be worth the work.
