Thoughts on modified '72 GMC Sierra 1500 towing capacity? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi:

I've changed my Sierra 1500 around a bit, curious what the original tow capability is to safely tow and what (if any) my mods have done to that?

The truck was originally a 350/350, it's now a 509" 540hp/600tq BBC, Stage III 700r4, and has a fully welded Dana 60 and an upgraded driveshaft.

The truck is rear leaf springs, and is a long bed. I have a hidden hitch behind the license plate from ECE.
