using 4781 base plate on a 4777 carb can make a very big improvement on a low powered car.Takes some tuning and possible booster venturi changes to optimise.I did that before.The dyno time cost more than just buying a race prepped carb.I also used a 660 center squirter and it had fabulous wfo performance but it was grotesque as a street carb.
