whenever you get them, doesnt matter
im almost positive those are the 1.94/1.5 valves though
do you know if the 400 is a 2 or 4 bolt main?
and just for the hell of it, i had someone do a lookup on that 327, and here are the specs: “327/275 with a manual transmission from a 1968 Chevelle or El Camino assembled at the Baltimore, MD plant.”
i need a 327 block, but it has to be a virgin SJ block, i cant find one naywhere
