its a 408 with f1r, right now only seeing 12psi on a 3rd gear pull, i cant get traction in 2nd with drags, i cant speak for the other f1's but i'll let you have first shot at this one come feb 20.
yea, thats me last year, i was runing a 11.5:1 408, that was a all motor run. have the same motor now, but just swapped out pistons. and added the procharger..
