I appreciate that Tim. I'm not really hurting. I am running on the stock Chevy 305 chip that was in the ECM with the timing retarded by 10°. It runs real strong/good from say 1600 RPM up, but any funny stuff (hard throttle) below 1600 will cause a stumble and burp. The O2 levels are decent though, it's not running lean, and I don't fear any harm to the engine. I still have an annoying SES light due to no VSS, and I'm not using the EGR. I would just like to get it finished, put the glovebox back in, and just drive on to the next project... whatever that may be.
