Believe it or not, the RAV program was a failure because the motors were not as good as the RA IV. The tunnel port heads were a great concept, albeit one ripped off from Ford, but, according to sources who were there, they couldn't get them to work as well as the IV heads on the 400 C.I. block. Now, do a little work on them, and, bolt them onto a bigger cube engine, and, look out. From everything I've heard, however, the "stock" RAIV would outperform the stock RAV. Now we have something to keep our new Pontiac friends around to discuss. Any opinions? LOL
