That is correct. Traditional Pontiac shakers usually fit most traditional Pontiac v8s without much issue (assuming intake height and motor mounts are factory dimensions), the Olds 403 ones are specific to that engine (offset a bit), the 301 and 305 are all different as well (height mostly). Then there is the fun of dealing with Can-Am shakers (for 400 and 403, both different) and the 1974 GTO shaker thrown in the mix.
