Ive got a proform main body, metering blocks, and fuel bowls. The only thing holley left is the base. I just changed the bowls because I stripped the float adjust nut out of the holley bowl. Ive now got a weaker pump shot then before. I know thier customer service is crap when I got no reply from their internet tech support from 6 weeks ago, and they list no phone number that I could find. I wont buy thier stuff again just for that reason. Whats yours doing or not doing for you.
