you will then need the finespline rear. and a good clutch. put a 15-17 gearset in , lower pinion retainer, weld up your shift forks so they don't bend. run it at a few pulls and then if you need a faster gear then you can toss a OD in.
if you don't have a clue how to do this then just send it to someone who does with a blank check or a box of big box of cash . otherwise its just trial and error and allot of beating your head against a wall  |
OK. I have no problem spending money. Just don't like wasting money. Steel crank? Why. I will not be running over 4000 rpm. Same for balancing. I am thinking deck the block, shave .04 off the heads, add a good cam, and I am good for 5 extra horsepower. That should be enough to get me where I want to go. If not, I'll add more next year.
What I would like to know is given the above mods and using 23" tires, what overdrive should I use? I am trying to shave a year off tuning and just come out next year ready to go. Without an answer, I would just go 10 percent. Any thoughts?
I will post pics of the last new Carlisle Super Lugs on the planet soon. After comparing them to my Destones, I can see why they are so popular.
