He has a 1923 240Z ???? Have you asked this question on slantsix.org ?? Someone there should know the answer. I can't see any 1BBL doing you any better cause it'll only flow so much. Does anyone make an adapter to put a 2bbl on the single intake?? That might be an option. As far as not having to warm it up before you can go is a function of choke/cold enrichment. A newer 2bbl might function better. The Z probably has some computerized control to aid in startup and cold running.
