Ok I have a 302 that the PO told me came out of a Granada. He showed me the mild mods he made to the car but he never got around to putting new headers on it. Stock manifold on it now. I went online and looked for 302 tri-ys and found quite a few of them but some of them say they will fit 65-70 289 and 302s. I don't know if there is a difference and wanted to ask. I always thought a 302 was a 302 with the exception of the smog stuff they did to the heads and stuff in the 70s. I am just looking for something I can bolt on. Looks like 2 1/4 pipes the rest of the way back by the way.
