1988 GMC 3500K Sierra advice
I have owned a 1988 GMC 3500K Sierra for many years. I want to buy a travel trailer and am wondering what limitations I should be concerned about. My thought is to "practice" hauling in my home stat...

Down low I think my TBI 350 pulled as good as my vortec, but once you hit about 30 mph the Vortec felt a lot stronger. Having a Tbi in a 3500 would make it pretty doggy unless it had at least 4:10's. The OP's truck will struggle over 6,000 IMHO. He is the only one that can decide what he is comfortable with. Everyone is different. I work with a guy that had a 2500 with the 350 TBI and he had a few grades in Minnesota where he had to use 4 lo to make it up with his horse trailer.

Tbolt,
Now that I.think about it, the 88R/V chassis also had tho except for the.C7P 10500 giver C7P chassis set up like my 89. While.the.same hp torque specs, the.power.curve was.enough.different that the 88 K3500 felt more.powerfully than the 89 R3500.
I also do not remember that axle.differences enough on smaller rigs. Other than what I recall from earlier postings. I could not get a locker with a BB in my 88 due.to using a dana70 vs the ff c14 in later models like my 96 k3500.
The tbi and carb versions of.the.4.3, 350 and 454 were way.under powered vs the.vortex.models. Had a 2000 4.3 safari van that felt every.bit as.strong as pre vortec 350s. My.vortex 350 is stronger than 454s mentioned.
