    Gears - I believe that blazer has 3.07's if its an auto, and 3.73's if it's a stick. 4.10's or 4.56's will make a huge difference. I run 4.56's with 40's and a 350 and it's still pretty good, but I'm going to go down to 35's. I can't wait to see how much power it has then.

    Hi, Welcome to CK5, its the best K5 site on the planet.
    A K&N filter will help some. An MSD ignition will also help a lot.

    Man, there is plenty of stuff you can do to get more power. First, get a summit catalog at http://www.summitracing.com

    You might wanna start with a new K&N filter, a set of Flowtech afterburner headers and an MSD box, then you can get a starndard rebuild kit or even better a stroker kit! While rebuilding, you can toss those old cylinder heads and get a a pair of Vortec heads from http://www.sdpc2000.com. Top it with an Edelbrock Performer intake manifold and Edelbrock Q-jet. If you got big bucks, get the Edelbrock Multipoint fuel injection system instead of the Q-jet. If you plan on sticking with the 33" tires, you should use 3.73 or 4.11 gears. http://www.4lo.com has a nice table that will help you choose the right gears. A nice rebuild on the tired old tranny, and you got yourself a Blazer many of us dream about.

    And tell your father ALL of this will be WAY cheaper than getting a newer Tahoe or Yukon and will be WAY more POWERFUL, STOUTER AND RELIABLE than a second hand vehicle.

    Good luck, and I hope you stick with your blazer.
