In street trim his Firebird on DOT's it runs into the 11's! Do the math on that at 3600lbs race weight as see if that cam makes just a little bit more power than the XE262 or 268 in the same build?.......FWIW........Cliff

Our 406 with xe274 can did that which seems to me is closer to an apples to apples comparison vs the 262 or 268 cam
