Yup, those mods and a tune you're looking at 13.7-8 easy.
a guy running this cam with a extended cab 5.3 his best was a 13.8 with 342s
cold air ,pace setter longtubes,3000 stall,tune.....
yeah ive only raced 3 times at the track, my best was 14.4, dont remember the speed or anything, and it was on 20s. Honestly was hoping for better.
pretty sure i still have my slips at my house back in oklahoma so i can check this weekend.
it was also hot as hell and once i made a pass after it cooled down i spun bad off the line.
oh yea them 20s slow u down bad....the ext cab was on stock aluminum wheels
