    Hi all, Thanks to this site, I am slowly starting to make great improvements to my stock 88 k5 with 80 K miles on it. Currently I am running 32" tires and have just added a 24 GVW tranny cooler to help the 700r4, (It says Thanks) a single 3" Flowmaster exhaust with a 50 series muffler, Catco cat and a 02 sensor. I flipped the lid of the air-cleaner (that alone gave better throttle response with doing nothing else)
    I can feel more power, Sounds way cool, and I am guessing the MPG will get better if I can ever stop from mashing the pedal so I can hear the new sound and feel the power:)
    Currently I have 3:42 gears in the factory limited slip 10bolt. Should I go with a cam/intake/ and a smoothed out throttle body as well as the TBI package from turbo city or change gears to 3:73. Mileage/reliability are concerns as well as best bang for the buck. These will be my last grouping of mods for quite some time. The Cost, Approx 2,000 for gears installed with a traction device in the rear or 1000 for the cam and intake with installation. I have not done much engine work and have to pay for the installation unfortunately.
    Thanks in advance for your thoughts and opinions

    If you are planning to go to bigger tires at a later date, I would skip the regear, because you would end up having to do it again. I would go for the cam and intake setup personally. I'm sure you could do it yourself. If not, I bet you know someone who knows how and would be willing to help. Motorheads love to work on stuff, no matter what it is.

    Thanks. I doubt I will be going to any bigger tir in the near future. I'd like to keep it where it is height wise. Also, mileage is a concern .

    Forget the re gear to 3.73. If you're not going to go for 4.10s, don't waste your money re-gearing as it's not a big difference to go to 3.73 from 3.42.

    I personally would run 4.10s in that truck. 4.10 is the ideal gear for 33s, and 32s are close enough to that IMO that it wouldn't be such a bad idea.

    $2000 for a gear and posi unit install??? That's nutty!! Just go buy a 14b rear with 4:10's and a lockers for a few hundred ($200-500) and you still have $1500 left over for your cam and whatever else /forums/images/graemlins/thumb.gif

    You should be able to find a set of axles with lower gears for less than $2000. You could even buy a whole truck with the right gears, trade axles and then re-sell the donor truck with your 3.42's. Also, a 10b ring and pinion shouldn't be much more than $200. Install the same. That's about $800 + the cost of the posi, which also is much less than $2k
