S.W.F.A.S.T.
Some-what factory appearing stock tire.
Sorry, but crazy is right. I don't like it, but hey, as stated, its their class and sanctioning body--not mine.
I agree with wize too, but the carb I worked on for a guy was correct for a 428 , not sure if the 429 was the same. The rear bowl supply line was no more than 1/4 inch. I would "almost" bet my car there is NO WAY you could run 140 mph with that.
Everything aside though, these cars are awesome.
(and the plymouth should be allowed one blaring none-stock performance enhancer just to shore-up this little indiscretion),
