Re: ZL-1 #65 reunited with her original engine!!!
There would have been multiple pour points in the mold, and several vents to let the air out as the mold is poured so you have no voids. In 69 the quality of the aluminium was poor compared to todays aluminium alloys. Many more heads and blocks would have survived. Roger
