Just wanted to update this thread. I did the EFI conversion and went with the Holley Muscle Car Module,
https://www.holley.com/products/fuel...s/parts/12-302 and the install of the module was very simple. It made one of the worst parts of the upgrade the easiest. So far it is performing very well. I even ran the tank down to 1/4 and did some hard accelerations and there was no issues. Even at max throttle and high RPMs the unit has no problems giving the EFI what it needs. It is also designed to work with the Holley Sniper so they are a good match. I also highly recommend the Holley Sniper and Hyperspark distributor, great upgrade.
