Thanks for the info. I'm not swapping the cam just yet as I have more pressing things I need to focus on (getting my shop enclosed). For now it's just fixing some things and making it run decent until I verify everything else is functional condition. Later I plan to pull the engine and do a complete build.
I did end up with the Wieand Stealth Intake (Summit bargain bin) and I can confirm that there is a bit of shift. Some intake mount holes were a pain to get lined up, and the back of the intake manifold is really tight on the base of the distributor housing.
