i'm runnin it ,using 600cfm carter competition series carbs...it's not the fastest set-up, but i like it..you can't beat the nostalgia look of the dual 4's.. ...i can't really speak to the streetability of it...i had a few issues at first gettin them to idle(i had no instructions or exp.)..but with alittle help from a few of the members here, we got it to run. car idles fine and drives good at low throttle thru the pits- with no problems...
