This car is mostly a fun street toy occasional take to work. Sounds stupid for me to mention but I just love how the 292 mopar cam sounds! Just want to make it work. As for the thermoquad it was used before on a 1970 440 drag cuda. So it has opened up squirters and I think 1966 primary rods and also they told me secondary jets were changed. No front flap door nust open! Works sweet in my opinion. Oh its an 850 version.
