Same question also switch for dual plane to single or any other mod that...

    Engines with lack bottom end power?

    I thought the general consensus was engines that were soft down low in the rpm band was a lack of torque. But I've been noticing that built engines of all type even high rpm still make decent power down low generally far better than a stock low power version of itself some on par or better than...

    AWD vs RWD

    I got a beat up 98 Jeep Grand Cherokee 5.9 AWD, I want to turn it into pure drag only. Would it be better to try to keep it AWD or switch it to RWD, I’m guessing RWD will be better, but don’t have and track experience, wondering what you guys think??

    Picking gears

    Just got a 68 Valiant not too long ago 360/380hp create engine, 2800 stall 727 with 2.96 gears. I want to take it down the strip a few time with the 2.96 gears but looking to upgrade somewhere between 3.55 - 4.10 haven't narrowed it down yet. From what I understand you should be 500 - 600 rpm...

    Gearing ?

    I'm just playing around to see what my options are. So I got a 65 cuda with a 318 when done I'm hoping it can do between 100-110 in the quarter mile. So let's say it does 105. I hear you want to be 400 - 500 rpm past peak power so say I want to be 6500 rpm. So that would be 4.56 gears with 25"...
