The smallest 4 bbl they make is a 390 with vacuum secondaries. I ran a Bob
Sharp intake and carb on my Z. Helped a lot with cold starting in the winter
and I got phenomenal gas mileage too. 30+.
It still hauled ass when I put my right foot down.
I think they make smaller 2bbls but not that small, however a Vega Holley
may fit. I think that POS was 2.3Ls
