I doubt that combo will back up 600 horse on a timeslip.
My W5 motor( when i had it) MIGHT have made a true 640, and it went 9.80’s at 135.car weighed 3350 with me in it on super stock springs. And taking 40 horse from that isnt gonna make a huge difference
If its 32-3300 pounds and isnt running WELL over 130 it aint making 600.
Not trying to bust balls, just a realist. People often toss numbers around that have zero realism at the track.
Mph at track is the truth serum
Rant over..... lol
