Can't say what I have, I know they were designed for a thunderbird. What do these Fentons look like, because I had to mod my headers to make them clear the steering box, and also so that they didn't dump right into the cross member.

I thought I heard that Fentons didn't even flow as well as stock car manifolds.  Could be wrong, I'd go with the Ram Horns.

I don't think any of the Fentons will fit an F-100. Chances are the drivers side will hit the steering box.

I've got a line on the Fenton Dual Exhaust Manifold and am wondering if it's going to gain significant power over the ram horns. I had a 272 that I've run with the rams. I'm rebuilding the engine to a 292. Does anyone out there run a set of Fentons on and f100? What luck have you had with them?
