Input please

904 has smaller internals and lots less friction, If you get a good convertor you can even have more stall and still be ok on the street, I would talk to PTC converters,if your interested, Good product and good price. I would stick to Holley Carbs , my preference or Quick Fuel. I went from a 727 with a T.A. 3800 stall to a 904 and 5000 stall 8" PTC and picked up 7 tenths,but I had more cam than you. You will also need a different driveshaft.
