Help with exhaust manifolds for a 66 cuda

I have a 66 CUda... it has a /6 k frame and a 69 340 TA motor backed by a built 272 tranny... I had my headers custom made to my configuration ( NOT CHEAP $1300)
I have no issues with the starter or oil changes....

I have a set of 66 Barracuda 273 exhaust manifolds media blasted and Ceramic coated black if you have a 273 or a 318 they will fit....if you have a 340 they will not...If you want a set of Stock 273 exhaust manifolds let me know, they bolt right up and require no modifications and served the 273 HiPo in 66 just fine.
