The problem is they aren't made to a quality standard anymore. You can't go down to the part store and pick up something that is going to be remotely reliable even in a mild application anymore.

Seconded, if you’re staying carbureted, check out the Progression ignition. It does what you needs.

FiTech will log, but only its own sensors. You can’t log anything external with it. So no way for me to log fuel pressure unfortunately.

Certainly possible. I purchased a complete rebuild with the new pump including a new pigtail, just in case that was an issue.

If the new fuel pump doesn't cure the issue, I'm going to purchase an IH micrometer and some checking springs. I can get that information from there.

I agree with this. It's probably not worth it on a mostly stock 350 to upgrade to the long branch manifolds.

Another thing to consider that hasn't been brought up here is IF you can get a set of...

You don't have to use the Moroso tool. I used the harbor freight copy on my BHJ that I got from Nitemare and it worked fine.

BHJ also makes a correct 4 hole balancer for the Pontiac. It is designed to be an interference fit, so depending on your crank snout dimensions, you may need to hone the balancer slightly.
