Just a quick question, is there a difference in the TPI bases for a camaro and a corevette or are they the same. If they are different will the corvette base bolt up to the camaro L98 easily or are there other things that need to be changed as well. Finally is the swap worth it, will there be any performance gains or losses?

The corvette has the old style angle drilled into the 4 center intake bolts. The vette manifold has a different egr set up requiring a connection to your manifold or header to make work. If egr is not an issue you can put a couple of block off plates and use it. The head will determine if the intake center 4 holes will need drilling. If I were a betting man I would bet that there are no gains to be had over a stock f-body manifold. I suspect that they are the same internally.
