Be interesting to see how they work for you. We ran an early set on the dyno on a mild 408 and they didn't do anything great. Worked okay, just weren't super impressive. The big block TF heads were impressive right out of the box on a variety of engines so we were expecting a lot from the SB heads.
Buddy just got his Trick flow headed small block to the track for the first time the other day. 90 degrees, 3000+ DA
3100 ish pounds, 264/268 flat tappet, 727 trans, convertor from another combo( W8 deal) not specced to this motor.
Victor, 28 tire, 4.30 gear.
Ran 10.63 @ 125 and change right off the trailer. Brake line leak aborted the rest of the outing.
Didnt think that was too shabby. No tuning, pretty lackluster 1.50 60 foot.
Heads were right out of the box
