what thickness are you running on your engine front plate, and are you running a mid plate? i can not tell from the pic. I am putting a 66 together and was woundering about running just a front plate and how much flex there is in the chassis, although i am fully caged.
66 long bed, old engine went 10.78 @ 129mph,
this is the new 496, made 690 at the crank on the engine dyno with 92 octane.
