well my push rods are so posed to be here tomorrow. so that means i have to get off my butt and start building my 73 dart again. I have to take the 4.10 gears out and set them up right. so i was wondering if i should leave the 4.10 in it or go to the 4.56 gears. I have both sets of gears already so i wont be out any money. here is a little run down on my car.
1973 dodge dart weighs around 3400
11.1.1 440
Indy EZ heads flow 310-315 @ 600 lift
comp solid roller 264@ 0.50 and 634 lift
mopar m1 tunnel ram 2 750 carter carbs
727 with 10 inch turbo action 3800-4200 stall
M/T 275/60/15 drag radials.

I was thinking about using the 4.56 because i don't have enough converter right now.would the 4.56 make up the difference for the mismatched converter? look forward to your answers.thanks Mopar65



If its a race car 4.56 at least but you already
