It has a 318, newer one tho, and after driving it around I think I will keep it a gasser. I really like the sound of a V-8 thru headers and duals. I get my oil burner fix from my 6. 7. Now if I get that winning lottery ticket, there will be a First Gen Club Cab 5. 9 manual trans Dually sitting in the 6 bay shop I would build. Maybe that should be an 8 bay. I think the 2nd Gen is a great looking rig, too. Also need room for 2 Ramchargers, a 2WD, lowered & smoothed; and a 4WD, with Cummins power.
