Do you use a proform carb???
The more i do research on this it seems the proform carbs are really good.
The 750 proform is $520.00 brand new.
I also found out that the new proforms are all aluminum.
Both the older design made of die cast -(zinc) and the new -all aluminum- proform carbs are available for the same price.
I like the all aluminum proform 750.
They look just like the quick fuel carb and have changeable idle feed restriction! (jets)
This is something you only get in a very high end carb.
The Q series quick fuel carbs don't even have this.
You have to buy the race series quick fuel to get it and they are $300 more.
Holley only has the new street carbs in all aluminum and the dominator ultra.
I would bet all the money in the world that holley won't even have a high performance hp or ultra die cast zinc carb available in two years.
Everyone is going to billit aluminum carbs.
