Just did this upgrade about a 4 weeks ago. Bought the kit from Steve J and was not sure at the start. Went to the dyno and seemed to run rich in the center plugs. Sbf 388 with super victor. most know that fords have lean conners but this was the other way around. took it to the track and worked great. had good plug reads and was 11.7 afr the whole 1/8 mile. on the 300 hp setting was loose on the top end but jetted it to the 250 setting and ran the same # it did on 250 in the rpm plate.
thanks steve j for what help i needed and cant wait to use the flow tool.
