my 63 Dodge had 5.13 gears when it had the original 426 stageII...had 31" tall tires

I now have a 9" with 4.57's...and thats with 32" tall tires..mine will weigh a whole lot less than yours and I'll put it on the street...if I dont sell the Duster whole I'll put the 499 in the 63 with Hilborn tall stack injectors...I think that would look period cool..
