Starting 340 Build w/ Supercharger

I agree with AJ as far as the traction part is concerned. On the street there is not much when a 6-71 is in the mix. You already answered most of the questions I had. You will probably need a new TC, one with an anti ballooning plate. The tranny should be something that will withstand some serious HP and TQ. As far as the rear is concerned I would think an 8 3/4 would work fine. I have 3.23 gears in mine and I like them. You make up for a lot of gear when you add the torque that a blower gives you and the 3.23's make it a joy on the highway. I would also stick with the 340 and not spend the extra on a stroker kit. The stock crank is great if it's forged. You can get an extra keyway cut in it if you want but it is not really needed unless you plan on going over 10 to 12 lbs of boost which will be hard to do on pump gas. I am a big proponent of H-beam rods and a heavy piston. The extra weight helps cushion the shock of the fuel explosion. That's my opinion, so take it for what its worth. I also run SS springs, frame connectors and 10 inch M/T radials. Where did I read that at. LOL I will repeat myself and say don't skimp on the cam. Mine has .565 lift, [email protected] duration on a 113 centerline. I normally run 6 lbs of boost with 91 octane but can turn the wick up to 10 lbs when I change pulleys and turn on my meth injection. These are just some ideas from somebody running a 340 +.30, 8.2 CR and ported "X" heads with a 727 and 8 3/4. Hope this helps. I get stopped by the cops as well. Most of the time they just want to look at the car and talk. LOL
