I don't have either, but those two manifolds have completely different applications. If you need something with small ports, a dual plane intake would be next up from the VERY low rpm SP2P. i.e.: LD4B, Performer, Mopar, etc.
i have an sp2p laying around in the garage. its dirty but im willing to sell it if your interested. sorry i dont have a picture. i can try to take one but i wont be able to get my camera till sunday.
