STAGE II


Recommended Posts

Steve Dove's book, BUICK Performance Engines<BR>references a STAGE II option available in 1968. This option carried over to 1969 and then again in 1970 with the famed D Port heads. <BR>Question: Are the 1969 STAGE II pistons still available ? Part #TRW-1394179<BR>This was a dealer installed option in 1969. In 1968 the STAGE II specifications were filed with NHRA. Are there records of the car and its performance? I assume that these were 400 engines, however I SAW 430 STAGE II VALVE COVER STICKERS at the GM restoration display at Carlisle last week! They were repros from Jim Osborne. Were any of the STAGE II engines actually converted GS 430s?<P><BR>
