The reason for my question is that I'm going to look at an 88 this weekend and if it's nice enuff I may buy it. My only experience is more than 20 yrs ago I had a 85 D350 with a 360 and it was an extremely strong combo. That old truck had been used up as a wrecker and was in terrible shape except for the running gear. My son used in it calif to tow his race car to LACR and there were none of his friends 454 Chev duallies that could keep up with him going up the grapevine. The thing was great for a 360. I hope this one I'm going to look at will be close in performance.
