HI Randy,I had my 69 roadrunner there last year great guys,I have a 471 with a six pac cnc eddy's by Jeff and 590ish bullet cam with 260 ish dur@50 and I made 460 at rear wheels. My best run last year was 11.09 @123 with a 1.58 60 ft. I switched to a 4 barrl this year hoping to use the head work with a single plane intake and 1000 pro systems carb,but haven't made it to the track yet. Let us know how it goes EDDIE B
