Yes Sir those guys went fast !!! i was there in 63' when he went ' 289 ' with that small hemi 255 cid i think.
This was before the fairing etc just the 6-71 and 4 port hilborn with the oval grey scoop, a real race car looking good in the nice yellow paint job.
Not sure how much faster a tank has gone since, also his was stock length too.
When he stuck it in top gear he lit up the rear's and i will never forget hearing it freewheel, wow was that cool !!
Like the rear shot of your tank too , what color will you paint it?
Don the tank fan
