What are the specs of the cam? I run a 410 with 10.25CR, TF heads, AG intake, 246/250 @.050 solid roller (would be considered on the smaller rather than big side yes) Dougs headers, 4.10, 27 MT ET street s/s with a Tiurbo Action 3500 tight. It flashes to 3500. All timing marks are rock solid consistent run after run. I run mid 11.40’s 1.58/1.60 60’, front wheels come off the track at launch.
