okey so yall just send me a 72/74 manifold for free and ill check it out lol :D
i also dont have any hard data that the 6a13tt manifold has bad flow but looking at the oem intercooler pipes it would not suprice me.
i was also thinking of checking if it would fit maby a outlander or pajero throtle body would fit.... (just a thought have not looked into this at all)
