ZZ4 intake for TBI?

Looking for feedback from anybody using a ZZ4 aluminum intake manifold with TBI. This looks like a pretty good intake and they can be had pretty cheap on ebay. Curious how this performs compared to a Elelbrock RPM.

there pretty much the same, but the names and companies that make them are different, they perform the same

those intakes(zz4) are for pre-87 heads aren't they? if so you'll have to modify it for use with stock lo3 heads.

You are right, the center holes will need to be masaged with a die grinder to make it work on 87 and up.
