It still amazes me that Shelby takes a beating here on what ever he touches,the Alloy SA block is NOT a center or top oiler,it is a MUCH improved version of the side oiler configured in a way that slinging a rod thru the left side dosent destroy the block as in the original ones,the
oil galleys are just moved up ,it still works the same,it's a good deal,,wish i could afford one,,Tk
