ZZ4 engine carb selection


CCCUK Member
Hi all.

I have a replacement ZZ4 engine in my ‘70 coupe and I’m in the market for a replacement carburettor. Mine still has the original Holley 4150 on, but it has far exceeded its life span. Plus it doesn’t have tuning on the secondaries and needs re-jetting on the primaries.

So, anyone who has a ZZ4, what carb do you use? Any recommendations?

Why don’t you look into that FiTech injection, mate of mine uses it on his 455 TransAm and it fantastic, I personally think carbs are a thing of the past! This system he’s got is totally amazing.

Supports upto 400HP, there is a 600HP kit $100 more!
