318 intake manifold performer or 318sp2p

[VDART]

I have both of these manifolds for my 318-- mild cam/stock exhaust--- it will go in a 69 dart convertible-- is there any difference between the 2 manifolds? Or are they so close that it doesn't matter? This car will be a sunday cruiser/ fun car--
thanks-- Lawrence

Performer. The SP2P would be worse than a factory iron 360 manifold.

The other difference is that the SP2P has correctly sized ports for the 318 heads.

As will a regular Performer. Note the SP2P has those sharp 90 degree bends and far narrower runners. For an ultra-lean, gas mileage only engine, this may help. But not for performance.
