budget drag strip car build Q's

I have an "X" head 340 in my Dart sport that runs high 12's. It has a MP .509" lift hyd Purple shaft cam, Edelbrock TM5 single plane intake, 650 holley DP, MP electronic ignition, Hooker headers, 3.91 posi, 727 trans with 3500 stall converter, etc

Use those heads and shortblock with a big hydraulic cam. Use a 4 series ratio gear (4.10, 4.30, or 4.57) with 28" diameter rear tires (I actually use a 3.91 with 26" tall hoosier slicks). The spool will work fine for a track only car, might want to consider a sure grip for a car that is stret driven (spool can get dangerous on wet conditions you could see on street!).

a 904 trans built properly is quicker than a similar 727 (less rotational weight), but a stock 904 might not be durable enough for a strong 340.

Stall speed is dependent on the camshaft, gear ratio and how much you using the car (track only, street strip,etc). I use a 3500 stall turbo action 10" converter in mine.
