I have an 87 suburban that started out life with a 6.2, when the motor got tired I swapped in a 6.5 with a banks turbo setup and at the same time had the 700 built/beefed up and I really like how it runs now. I always thought when the time comes that the 6.5 gets tired I would probably swap in a gas motor but after fixing up an 87 blazer a year ago with a stock 350 gasser, there is no way I would go with a gas motor in the sub. The 6.5 runs circles around the blazer and I can get almost 5 mpg better with the 6.5 than the 350 gasser. I am building an 86 crew cab with a 12 valve cummins with an allison behind it but it will be another year before its on the road so I cant offer an opinion on that just yet.
