from my 76 and replaced it with 40 downdrafts. I like the HPs uptop after I put the new carb in as well as a freeflowing exhaust together with new headers. the 32/36 ran fine but I wanted more acceleration and more topend. Are you interested in my 32/36? I'll give you two for the price of one. I have no idea about the back uup one for it came with the car and never had it ran. The other one is in great shape.
