The real question is why is an 8.1L/4L80E swap not more common. It is a much better truck engine than an absolutely gutless 6.0L or 5.3L. An 8.1L is on par with a 6.0L as for fuel mileage and has another ~200 ft/lbs of torque down at 2,000 rpm where you spend 95% of your time driving at.
My 8.1 kicks my 6.0 in milage and every other way also

They are around. I know of 5 8.8l psi long block cores. The 8.1 are around. Van and suburban will be 4l85 and the van and big stuff(top kick/ Kodiak) have the high mount ac bracket

@Dropped88 has done 2, with my truck waiting on me to get time to take him a motor so he can do a 3rd.
Right on. I'll search for his posts/threads.
I honestly haven't even looked for one around here, but I'm sure I could dig one up, and then change my mind when I see what they want for one, especially a pulled one already. A few years ago a 5.3 went for $500-$600, now asking 1k. And 6.0s are 2k now. Could only imagine what a 8.1 would go for ready to go.
But the pick n pulls around here ALL the motors are $350-$400ish, just gotta put the sweat equity in.
Thanks for the lead.

If he hasn't written it up shoot him a PM, I'm sure he'll share what he's learned.

I know my decision was the number of 5.3's that were out there and parts available. Also it bolts directly to my 4L60E already installed.

I got both of my 8.1Ls for less than the cost of one 6.0L here. Both fully dressed with the high mount ac brackets.
