Heres the little brother to Wayne's throttle body, flows 1200 to 1300 cfm, I did near 550 ftlbs @ flywheel with 42's in a mitchell 427sb. Extremely mild cam, I believe theres easily 600 in it using the 42s. The throttle response is very quick.
I wonder why Wilson milled the injector bung bosses almost completely off before installing and welding the bungs, hmm?
