I don't think we will ever see any new small block mopar heads released again...I just don't see the market for them going forward... plus there are lots of W8 and 9 heads floating around we just need a decent block to work off..
I would take that bet as there are way more guys looking for a more racier TrickFlow Head. The costs involved in running a W8-W9 head and high rpm gets expensive real fast. I see those guys spending 1000’s of dollars just getting the right convertor in the car. Way overboard for street, street strip budget racers. TrickFlow made the smart move releasing the head they did.
