Ive been using quadrojunks and they seem to be good to me.But i plan on building a zz4 with the hot cam, would a performer rpm quadrojet intake work with a modified quadrojet? Would the holley with the regular performer rpm be better? Either way id like to stick with the l69 aircleaner.

 

I don't believe the L69 air cleaner will clear the fuel bowls (float adjustment screws, actually) of the Holley.

I found out my '66 air cleaner had the required dimples to clear the bowls, though. I had to add the snorkels.

 

I assume you're building a ZZ4 clone. Otherwise, the engine comes with a fine intake (see sig above).

Here's a pic of the dimples to which I referred. Not a very good shot, but they're at 3 & 9 o'clock.
