Hello folks, I have an 85 1008 that has the banks turbo system, and a 4l80 od transmission. It still has the 4.56 gears as well. I know that even with the turbo the 6.2 is not making big power, but I figure if its making 350-375 ft lbs at a fairly low rpm with 4.56 gears it should have similar towing ability to something with 425-450 ft lbs and 3.42-3.73 gearing (thought with a lower top speed). Am I expecting to much? it just seems like the truck doesnt quite pull the way I had hoped that it would. I have been toying with the idea of getting newer truck with a 5.3 or 6.0 vortec and was wondering if they would do a better job. It just seems like on paper that the 6.2 ought to pull better than it does with the turbo and low gearing. I am planning to check the compression on the 6.2 as soon as the adapter for it gets it, it doesnt even have 30000 miles on it, so it seems like the compression should be fine, but you never know. If the compression is good maybe the ip or injectors are getting tired, or is it just going to be a sub par puller regardless? I'm not expecting this truck to compare to a modern diesel, or even a 12 valve, but It seems like it ought to hang with a 6.0 or 454 pretty well, and so far it really doesn't compare to my grandpas 94 3500 with the 454, or my dads newer 6.0 truck. just wondering if thats normal.
