87 IROC-Z A4 L98 V8 9.3:1 5.7 (350) 225@4400 330@2800 TPI ---- ---- 3.27* ----


the lb9 is a tpi 305 , the lg4 is the carbed 305 ,and the l98 is the top of the line 350 with tpi
and both lb9's used the same cams, and rating..
my 86 305 4 barrel makes 180hp(in my g body).. the tpi was not 190.
it's a miss print.(numbers game). if they had different cams the engine code changes..
