Should I have a concern with restriction? Does anyone have a Rooney manifold they can measure for comparison? Comments please.
Thanks,

I have an original used version of that LH dual manifold design made in the 50s-60s. The outlet measures 1 3/4 inches dia and that is the same as the stock RH side. Anyone need it?

Barn Junk,
I've sent you an Email via the Barn

Update, I sent the Drake manifold back because the outlet, in my opinion, was too small (see above). I have since ordered and received one of Pat Rooney's LH manifolds. What a difference!! This is a quality product, a copy of the original, used in early '50s police cars w/Mercury engines. Rooney's manifold is designed and cast in the U.S.
Kepich makes all the pipes for the duels with the left side being patterned to the Rooney manifold rear outlet. I have the Kepich pipes and mufflers to be installed after the engine goes in. I'll update this thread once I get the exhaust in place with details of installation.
