It would be awesome if they made a Metric60 bell for the later 4L80E with the detachable bellhousing.
I've seen a Riviera and I think an Aurora with a 4T80E and an L67. Documentation I've read said you have to remove one of the knock sensors and clearance the block slightly around the bellhousing to make it fit but that's pretty minor work.Central TEXAS Sleeper

joking aside, an allegedly useable 4L80e isn't that expensive - can you sneak them in as "used farm parts?" like I did with the 300tdi?Last edited by SuperBuickGuy; July 15, 2020, 07:28 AM.Doing it all wrong since 1966

I kid... I kid.
No, I don't think the 3800 will replace the LS for dirt cheap performance. 400hp out of a 6.0 LS is pretty much... put it on the dyno. Maybe a cam swap and headers for a 5.3 ... "mild" cam and headers on a 6.0 is an easy 500 hp / 500 ish Tq. The mill is genius. The thing it came I'm not always as fond of. The 4L80e enjoys good parts and multiple controllers too.
I'd like to see the 3800 with a hairdryer instead of a huffer. What is the general torque limit the block will put up with?Last edited by Beagle; July 15, 2020, 08:34 AM.Flying south, with a flock of bird dogs.

The whole weak transmission think probably limits taking it as far as you can as there is an L67 based turbo motor in a Grand National that was pulling down 700hp easy but again saddled with a 4L60E. Overall the blocks have a lot of more strength than the older 3.8L's with the crossbolted main caps, a solid valley, and thicker decks.Last edited by CTX-SLPR; July 15, 2020, 12:20 PM.Central TEXAS Sleeper

I'd believe the 1500hp number unless there's some defect like too sharp a radius on a main cap, etc.Central TEXAS Sleeper

I was going to ask about adapters because I'm a little lazy these days. I have not much love for the 4l60. That is probably because Dad's stock grandpa driven 4.3 S10 grenaded one with less than 100k miles and it had never seen serious work. We hear all the time how guys spend stupid money on them and still it's a grenade with the pin pulled.
1500 hp? Wow. Color me impressed.
Stock block, stock crank, how much will that hold reliably? Where do things start breaking? Rods? Crank? I'm not sure when 600hp became my magic number, and I think it's about to change to 700 hp... if it will tolerate that on the stock long block then I'll probably change my tune a little. I think it takes more thought than a 700 hp LS, but that's all part of this game right?

what attracts me the most to it is the V6 sound - they sound terrible - with a V6 in my 64 Wagon, no one will give it a second look until they wonder why they only see tail lights....
the other thing is the 3800 is in the same family as the 231 V6 (the Grand National motor) - it's not a Chevy motor, not at all. It does have a few challenges that should be addressed before you make power (ARP head studs, Cometic gasket) .... but again, it harkens back to when Buick spanked Corvette.
and Barra. Everything I've seen is 500 hp is about the limit with a Barra before major work is required to keep it together.... vs. 700 hp... and a shorter package.... straight 6s are cool for a number of reasons but it's like many other motors, it ain't cool if it doesn't fit.Last edited by SuperBuickGuy; July 16, 2020, 06:47 AM.Doing it all wrong since 1966
