That is cool part of the T type and GN story. Buick got their V8 pulled thanks to CAFE and GM's Coporate engine strategy. Much like the Pontiac 301 Turbo which no doubt would have seen improvement every year and would been impressive by the mid 80's, Buick kept at it. Olds did one improvement to the 307 HO, they had an extra 30 hp in the FE3X prototype, why it never made production is beyond me. Chevy supposedly almost got the TPI power plants in the Monte SS, again didn't happen. Somehow Buick snuck a monster past good old GM and made the Corvette look like a slow weinie mobile, that is truly why it became a legend. Pontiac had nothing but copycat cars to the Camaro and their G bodies had 0 performance engine options. Thankfully, that changed with the 89 TTA and they even improved on it some, it was the last TA that stood out and annihilated the Camaro on the street and track. I wonder if Chevy punished Pontiac for all the times it put outside impressive performing cars. The 80's, 90's and even the last WS6 version always ran slower than the Camaro, the TTA was the one exception.
