I just got a set of thunderbird exhaust manifolds. I also bid on a set from Ebay and got them too. I have a 272 with single exhaust now and want to convert to dual exhaust. I think the ones I got from Ebay are for a 312 passenger car. The question is, are they the same? I don't really know what engine the t-bird ones came off of. What ever I'll wind up with 2 sets and I guess will have to get the exhaust pipes made at a local shop. I see where Tee Bird has exhaust pipes in 2" diameter and 1 7/8" diameter. I think I'll do the 2" ones. They will be for a 56 Customline. What do ya think ?
