Wow, I'd forgotten how long it's been since I bought these manifolds. Info today is scarce, looking at forum posts 10+ yrs old, and they're called vintage now! Most comments I find are thumbs down on the Street Dominator.
I no longer have the Mopar Performance engine book, but didn't it recommend the SP2P? (am I remembering correctly?) But I don't see it working well with the square bore carb.
Thanks all!
