i'd pass on a block that's missing the caps, likely the caps are gone because there's something fatally wrong with the block. it's not as easy as just drilling the holes, if you're using factory caps they need to be fairly close to matching at the parting line or it'll take a lot of material to be removed to get there. to help get close before removing material from the parting line the shop has to remove material from one side of the cap and add it back on to the other shifting the bore in the cap over to match the other 1/2 of the bore in the block. yes they are off that far most of the time. all this can make a mess of the rear main & oil pan seal. top it off now you may need a special line bore timing set
is adding 4 bolt caps to an unknown block worth all this? HELL NO!
FWIW i bought a set of 4 bolt caps for $100, they came with the damaged block that i had sleeved & still don't know if it's fixed. to make matters worse i get the block back and the deck surfaces are totally fubar'd with drag mark gouges
hey, 4 bolt block for sale, 1 new sleeve & needs deck surfaces run / no returns!
