Question. Since this used to be a two barrel carb engine but now it is has a four barrel intake and carb, should I be looking for specs on a cam set up for a four barrel or still a two barrel ?
Short answer...no...That's not a factor. Just tell them what gear, trans, and what mannerism/rpm range you'll be driving in... say... idle to 6000rpm...then you can choose the carburetor 'cfm' based on that range..whether 2 or 4 brl.
