Furnguy, welcome to iRV2.com. We are glad to have you join us here and look forward to reading of your adventures. I bet that 78 Chieftain is on a DOdge chassis. I had a 78 had Champion Titan on that platform and it did remarkably well. Actually had more horepower that the 95 Ford 460 we later had in our Aerbus. Enjoy the forum and take care.
