I have no clue on the specifics but if I was a betting man I would bet that you will need. upgraded valve springs. Also you will want to check to find out if it says, “needs high stall-speed, torque-converter” and/or a “steeper rear end gear.” If it does it will still run with the stock rear gear but it will buck and chug at low speeds like when you’re in a parking lot. Provide a link on what you’re looking at.
