is the 305 in a z28 different than a 305 in a regular camaro? i have a z28 5.0 h. o. badge on my 87 z28 and i think i read somewhere that there is a year where there wasnt much difference between a regular 305 and a high output 305

 

86 was the last year for H.O. 305. In 87 TPI took over, and just the base 305 carb. The H.O. had higher compression (9.5:1 instead of 8.6) anda different cam profile. Also a dual snorkle air cleaner. Or the PO could have installed a HO 350 kit, GMPP # 10185077

 

ok so my camaro was sold in late 86 as an 87 so does this mean there is a hance i aught the last of the high output carb'd 305? or am i just decieved by the badges

 

No...All it means is the Z28 had 170HP Carb LG4 vs 165HP Carb LG4 in other 1987 models. Most 1987 Models were built in 1986.

 

ok. thanks for the replies guys
