I know this has been asked a time or two but here goes. I have a 44, 42.5 inj, stock convertor, good heads. I drive the car 75 miles aday. I need to know how streetable a 63E. and 55's would be. I know the convertor will have to change, I'm thinking a 9/11. Also I have the PTE super stock. I have a FAST also. It used to be a race car befor I decided to put it back as my driver.
