i race hot fords around tarmac ovals, its a mk2 xr2 with an early xr3 engine and gearbox on a square top carb,,
problem i have is we race in 2nd gear,, need speed down the straight and the pull out of the bends,,
ive got the pull etc but half way down the straight im flat out

i just need that bit more,,im on 14 inch wheels
some people say use diesel boxes as its got a longer 2nd gear?
ford gearboxes have tabs on with numbers, is there anywhere i can find out what type of box theese relate to ratios etc to find the best long 2nd gear?
