I have a 85 camaro iroc/z28 carbed motor.......is it 4 bolt...im pretty sure it is just making sure ;D

if it's the original 305 it's 2 bolt

if it is a swapped 350 could be either or.

all this is assuming your talk mains

its was rarer to find 4 bolt blocks in the later ones, id say its a 50/50 gamble unless you post us some casting numbers etc :)

if your car is carbed and it is supposed to be then it will be an "H" code, which is HO 305 which is obvioulsy a 2 bolt.
