66 gto tri-power but which manifolds? ram air
I am close to putting the engine back in a 66 gto convertible I purchased two years ago. PHS documented it to be a tru tri-power car so I am keeping the car just that but the exhaust I would like to change . Everything I read says the exhaust manifolds were not very good performers in 66 and I have looked at some ram air up grades. I read post from this site all the time and would like suggestions from some of you old chiefs. The engine is mostly stock with tri-power and 4 speed.
Thanks Hunter |

On a mostly stock 389 you're not likely to see much gain by going to Ram Air manifolds. The log manifolds (which would be correct on your '66) get a bad rap by a lot of people, but they're really not too bad.
If you do decide to get the Ram Air manifolds make sure you get the 1967 style. They fit the '64-67 A-body cars. The later ('68-72) style won't fit your '66.

thanks Goatless, I had been looking @ the ram air 67 manifolds but did have that question about the III's and sure glad I didn't order a set. If I order a set of the RARE manifolds what do you think about the up grade of coating or are they just fine as-is?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
