I have tried different carbs over the years. Different Holleys and Edelbrocks. My car is a 4-speed, with a healthy running 360 so I went with the manual secondary 750 HP instead of vacuum. It just runs better than any carb I have ever had really is all it boils down too. It is recommended to run manual secondaries with manual trans and vacuum with automatics.
On the Quick fuel website it shows adjustable or standard fuel blocks so I was just wondering.
Shoot!.... I'd keep the motor and screw the poor MPG! When I jumped into this hobby with both feet I new that MPG wasn't going to be the most appealing thing in the world. I know it can be done and have power also but not that cheaply... so screw it... If want to play I'm going to have to pay! LOL
