Mr 5&50 is a big inch Hemi in a 65 Belvedere with an original size, 2.5" and style Hemi scoop. He buys my AFX scoop 4.5" and installs it. Comes back 3 weeks later happy as hell and said it was the cheapest horsepower for the money. Cut 2 tenths of his e t without rejetting. The Shadowwoods 64 Plymouth max wedge heard about the gains over the original size scoop and orders another fiberglass hood and this time with an AFX scoop. I see him again a couple of months later and ask where the new hood is. He says he keeps it in the trailer for when he can' make the number, then he takes the AFX hood out and cuts 1.5 tenths of the e t and he is in the program. That AFX bolt on scoop for $325 is my best seller here at Sled City Fiberglass.
