Truck headers for Dyno

[c9zx]

My in car headers won't clear the Dyno frame. I know Jay tested truck headers in his book. What should I be looking to buy? 1966-1976 F-100 352-390? I would appreciate some info as the engine is already on the Dyno. Thanks, Chuck

I  think the truck headers you mentioned will work - Jay

Thanks Jay!

Depends on the dyno, Superflow has some room, a Land & Sea I used once ran truck headers, and most Stuskas need a dyno header that look like a T-bucket, they have to go out and away.

        And sometimes, particularly if the bolt patterns are symmetrical (like the vertical 8-bolt FE's) I've mounted the headers "up-side-down", then looking like a set of "over-the transom" boat style headers.
