2000 6.0 to 4L60E So i have found a wrecked 2000 model truck with the 6.0 and an automatic transmission. Im thinking of buying it for a swap into either my 70 chevelle or my 86 K10. I've been doing some research on the crank being longer on the 99-00 model 6.0 motors. They say it wont bolt directly up to a 4L60E transmission. I have seen a lot of posts about this but many of them are older and i was wondering if maybe someone has designed a work around for it in the last year or two possibly? Any advice before i make the purchase is much appreciated.
There are several options on this.
Obviously the last option is the most expensive and least practical, the first option is the cheapest and most likely to be found in a salvage yard or deal site.
Even though there are internet rumors to the contrary, in my personal experience the V6 4L60E isn't any weaker than the V8 variant. Now if you are drag racing, that's another story. If you like burnouts, donuts, hard but realistic and daily driving conditions behind a reasonably stock engine, it's fine. Especially if you keep the transmission cool and keep it full of fluid.
- Buy a 4.3 V6 4L60E transmission. They have the proper depth to work with the long crank 6.0. (I have done this several times)
- Buy a late Gen II 5.7 V8 transmission. They also have the proper depth to work with the long crank 6.0 (harder to find)
- Swap cranks from your 6.0 to a short crank.
- Machine a .400" spacer for your bellhousing to offset the .400" longer crank. (completely impractical for 99.9% of us)
