    What would you do? \'86 or \'91

    Need your thoughts. I've currently got an '86 w/ 108K miles, 4.56:1 posi's frnt/back, 35" BFGAT's, shift kit and 4" lift. Can be seen here: <A target="_blank" HREF=http://coloradok5.com/featurepics/davidwwhisman.jpg>http://coloradok5.com/featurepics/davidwwhisman.jpg</A>. But, I've not got my eye on a '91 Silverado model (no rust/dents, all stock, 116K miles in vgood shape).

    Would hate to lose the K5 Badge on the side (guess I could put one on the '91 but that'd be cheat'n huh!) but am really ready to lose all those vacuum lines due to last year of carb K5's. What do you all see as positives/negatives on the two?

    Thanks,

    Re: What would you do? \'87 or \'91

    You could always take the good things off your current K5 and transfer them to the '91, assuming you have enough cash to buy one without selling the other one. Is there anything wrong with the '87 that would make you wamt to get rid of it?

    Re: What would you do? \'87 or \'91

    I have absouletly no concrete evidence here but It sures seems this way. My dad has an '89 and I'd swear they aren't built as heavy as the old ones. Our '78 (God rest its soul), '81, and '82 all have a heavier feeling when you close the door or just tap your knuckles against the metal. Maybe they lightned them up when the pick-ups changed bodies in '88. I don't if its something you can put your finger on like when they changed trim in '81. Your '87 has less miles (not much, but hey), you've added alot of cool stuff to it and you know whats been done to it for the years you've owned it. I didn't look mine over close enough and had to replace several things and it will get a round of body work come summer. Then again, thats half the fun. I've had a ball putting mine back together, that way I can brag and say "I saved it" [​IMG]. A change is good too and fuel injection rocks, either way you're gonna turn out good.

    Call me crazy, but wasn't the last year of the carbs '86? i thought '87 was the first year of injection.

    Re: What would you do? \'87 or \'91

    You have a great looking ride and I am not sure it is worth the change. As you say, yours is carburated, TBI may be an improvement, and the 700R4 was upgraded in '90. As someonelse said, maybe you could take the good stuff off the '87, put it on the new one and sell what's left.

    shaggyk5, I have an 88 Caprice with a carb. 88 was the change over year, some Caprices had carbs, some had injection. I'm not sure if it was the same year for Blazers though, but I know it wasn't sooner.

    I've had my 88 for 5 years without a lick of problems from the tbi engine, By the 91 and combine the best parts.

    Re: What would you do? \'87 or \'91

    My 87 K-5 came with TBI stock. 86 was the last year of the carb on the fullsize trucks. Unless TBI was an option.. or something like that. I dunno, I'm the 3rd owner of the truck. I have to check that paper in the glove box. But I really think that 87 was the change over year.
    In any case, I'd take the tranny from the 91. Like stated before, the 700R4s around 89-91 were the best of the lot. I really have to go looking for one myself. Otherwise, I'd keep the 87 just cuz it still looks nice. I'm not into the newer style grille.

    Re: What would you do? \'87 or \'91

    If you can swing having both vehicles at one time, I'd be pretty tempted to buy the '91 and put on all of the good stuff off of the '87 on it (lift, wheels/tires, etc.). Then put the stock stuff back on the '87 and sell it.
    All of the mid-80's carbed GM vehicles I've driven seemed pretty doggy when compared to the fuel injected motors (I'm thinking there was about a 40 hp difference in the factory ratings between the '86 carbed engine and the fuel injected '87/'88 engine).
    In my opinion, the '90 and '91 models were the most refined and best looking of all K5's (though the full convertibles early '70s were cool also).

    The '91 has 30 spline axle shafts rather than 28. I think the tranny was built with better parts begining in '88 (maybe 87).
    I prefer the TBI over the carb simply because I don't have time to learn how to adjust carbs. I have an '89 and love it, if I had an '87 I'd love it.

    Might have been another one of GM's mid-year things. My '87 had TBI.

    Re: What would you do? \'87 or \'91

    Baby on the way & wife wouldn't be able to get the kid in safely. Plus, when I was looking for one to begin with, I really wanted TBI & since I discovered CK5 and read all the internal engine upgrades, the '91 looks very strong and its about 50 more horespower. I also had planned to restore the truck (frame-off) and figure down the road it'll be cheaper with the '91 because the one if found is in much better shape. Nothing wrong with the '86, it'll just take more $$$. And, I'll have to sell it-can't afford to have 2 & will leave all the good toys on to help with value.

    Thanks for the feedback,

    My bad on the year. My typo. It's fixed. '86 was last year for carbs on trucks per Chilton and AllData.
