73’ 318 dies under accel with new intake & carb

I'm glad that worked out for you, but it is not a reasonable solution in my eyes. Something is making your A/F ratio way too lean. Seriously, going to the max jet/rod combo to make an engine happy means there is a serious vacuum leak somewhere that you're trying to cover up.
When you check and check for vacuum leaks and none are found, then the solution lies in the fuel distribution. I even hooked the smoke machine up to the engine and found no area for a vacuum leak. Many other people stated this carb ran extremely lean on their mild strokers.
