The manifold shown in the 2nd set of pics is your best bet. I built a Super Stock 440 with it and it ran quite well. Can't remember where, but one corner wanted a jet way different than the others. A sheet manifold was tried, but the Weiand made more average hp.

Indy cylinder Head makes the ModMan intake. Interchangeable tops. Has shown decent HP improvements over a stock 6-pak.

Ari , they look great especially the Weiand . Which manifold runs best , Weiand or Modman ? What cubes and RPM are you pulling ? Have you tried stuffing the Modman ? thanks,
Tex

Ari, thanks again Michael , that's what I thought re the Modman . I have a dual quad Modman (stock port)that wasn't quite right for my 450ciRB but should work nice on top of a stroker

The Weiand runner length is optimized for the 440, it was specifically designed with the 440 in mind. A bigger engine would have the torque peak at a lower RPM with that runner length.
A bigger engine may like the mod man intake better and you could run it with max wedge port sizes.

Anybody try one w/ Stage VI heads? does the extra 3/4" make a difference? (talking Stock stroke 440 and small solid roller cam)
