Summit should have the gm ht383e and the blueprint variant. I’d also check with your local machine shop and see if they would build one and have it ready for you to exchange yours as a core later.

might be able to get away with 3.73s
Yes for towing! 4.10's are the minimum I want here, when I ordered my F550 I ordered it with 4.88's and never regretted it.What gears are in it? If it has 3.42s that would explain why it doesn't tow. Swap to 4.10s n would do much better.
YES! The 8.1 will tow like nothing else. I had a 2002 pickup with that and it was awesome, was stupid and got rid of it for a 2007 Duramax, which we quickly named the Pavement Princess, piece of junk.Personally I would probably search for a 2500 Suburban with a 454 or a newer 2500 Suburban with an 8100. Unless you swap to the 8-lug suspension, brakes and running gear the 1500 components will still be weaker especially adding a ton of power to an otherwise stock 1500.
If that's truly the case, your engine is barely broken in. Put a decent cam in it, uncork the exhaust, get a tune, and rock and roll.I know engine swaps have been discussed at length, but if you have time, let me know what you think -
I have a mostly stock ‘98 Suburban. During salmon season I pull a North River Seahawk (~5k lbs) and it’s downright embarrassing trying to go uphill.
I don’t want complicated…the more plug and play I get the better. I plan on doing the swap myself. Current motor only has ~127k miles. Will probably sell it unless there’s a rebuild option I don’t know about.
I think if I do another engine swap it is going to be a DIY clone of a L8P GM crate engine. Basically a L8T with a LT2 cam. $200 GM LT2 cam and long tubes turn that 6.6L gas small block into a ~525bhp and ~550 tq beast.My 7.4 is stock and will be getting a computer swap and a tune. Some one tuned my 8.1. It's in a 02 suburban with a 4l85 and 373 gears. It's a beast pulls like a freight train, is fast and is happy being driven like an old man. My favorite motor. I'm swapping the 8.1/4l85 into a 86 cab and chassis 4x4 with the 205 and 410 gears. Should make a great plow/ towing rig. The 7.4/nv4500 is going into a 95 z71 ecsb. My 99 k1500 suburban is getting a small block upgrade. 383 or 400. Can't beat torque for a driver.
