Douglas said to fit side draft Webers,you need to remove the brake booster.
Install a manual disc master cylinder,one w/a smaller piston, than the original w/power assist.
1 7/8",,,,primary tubes,,, that is really big!!!
Personally I would only use that for a strip car ,not a street car.
You are losing too much low end torque w/that size primary tubing.Wow!!

If you get a chance to race someone w/a simular build as yours,but has Webers,, let us hear about the race.
The 600 Holly DP is OK.
You have one thing going for you,, your car is pretty light.

307 rear gears are a litle taller(numerically lower) than what I would run for a street car.
Can you get other ratios for it?

You say you are going to have a new set-up, what is your new set-up going to be?
Thanks
