Doest the intake manifold from the Corvette '89 fit to my Camaro Iroc-Z (305) '88? Is that change smooth or should I do some drilling?

How abaut the plenum from the Corvette '89 to that same Camaro Iroc-Z (305) '88? I read that there I should do some drilling for the IAC? Is there anything else..?

 

If you're talking both are TPI intakes then don't bother.

 

I wonder how the people using the LT1 intakes are dealing with this problem?

The intakes are the same except for the IAC and the mounting
area for the MAP sensor. Leave it alone.
