What Year???
I bought my wife an '82 RC for Christmas. Bad engine... Knew it needed work, but put another reman 318 into it. As of now, there is not and once of doubt that I could have put even an old 6BT in it for what I have in it now! Frustrating, to say the least. I guess most of it comes from MY beast! It would be nearly impossible to sell me a truck(any for that matter) with GAS engine in it... New or Old. I LOVE my truck. The RC has SERIOUS potential, as far as I'm concerned and I can't the wife out of it! She loves it as it is. A Cummins would really do it the justice it deserves!
Post away!!!. . or email them. I' love to see everything that you are doing. I know it's tough to take the time, so IF you find some (time), please keep me updated!!
Thanks!!!!
