Reply to "roush motorsport single palne intake"

George PAdmin.

A pic is worth a thousand words, and I have some pics.

I have owned a couple of manifolds that looked like the one pictured above, they had A331 "stamped" into them, not cast. Like Doug wrote, the opening in the runners were about the size of the ports in the B351 head, with enough material to allow them to be opened up to work with the A3 heads. The manifolds had the bolt holes drilled out however, it is odd that the holes are not drilled in the one pictured. This particular manifold has thicker flanges than the A331 intake however, I suspect it has been cast for a 9.5" block. The rear valley rail should curve outwards Windsor style. Is that the A341 Doug? The Roush manifolds are not designed to fit iron 4V heads, they are designed for the high port SVO heads.

A Parker Funnelweb pictured below is designed to fit the iron 4V heads on a standard 9.2" Clevo block, with port stuffers in the intake ports.
