[BK72BURB_3/4Ton4x4]

Thanks all, look forward to tapping into the knowledge base and swapping stories. This will be my third Chevy in this vintage. Had a '72 K5 and a '71 3/4 Ton long bed 4x4 about 15 years ago. Glad to be back :-)
This factory K20 sub has a bored and stroked 454 mated to a TH400. Not sure the gears, PO said he thinks they are 3.73 but I wish I had the 4L80E out of my '91 burb! Wild 800+ mile ride from AZ to Grass Valley; 8mpg, 21 gallon fuel tank and broken fuel gauge...lol. Flew down with my 16 year old and had a nice father son road trip home...good times.
