Here is a tank I have been looking at.... eBay 4570135280

 

Thats a good one i used to have one like that but i swiched to a low profile tank it only holds half as much as the one on ebay. with one like that when you run out of propane you can usuly still drive it for quite a way ( only 35- 40 mph and it stalls lots but u can get it to the next fuel station.)

 

Ok well what is chiper to run on the 460 big block gas or propane those day

 

Alliance Auto Gas is one site I ran across. They seem big into the propane conversions. Would like to do the conversion also. Ordered my truck with the natural gas/propane prep package to do it if prices ever get more reasonable.
