1979 Pontiac TA NCE Convertible / Yenko 427 Motor
Sharing some pictures of my 1979 Trans Am, #1 of 250 NCE convertible conversions commissioned by Pontiac with National Coach Engineering (NCE). The car has a complete Yenko 427, with matching heads, intake and the 950 3-Barrel Holly Carb made for the 427. The heads were modified by GROMM Racing and appears from the engine builder as a 460. Which is a 454 .030 over.
