Needed matching to use an aftermarket block???
Needed machining!!!
Obviously there are things you may need to do to a IAII or a Kauffman block when you get it... Boring and honing to you specific size, I am sure. I don’t know if all blocks come with same size bores? I wonder if many need to be decked to get desired compression height? My biggest question is concerning the block to head coolant holes. Pictures I’ve seen of the blocks have no coolant holes. Could different applications need different holes, and locations? I’ve read how Smokey Yunick made modifications on the small block Chevy, for better cooling (although all his stuff was hardcore racing applications. I am sure the Pontiac cooling system is similar...) My potential use of an aftermarket block would be a conservative one. I would use the .842 lifters, standard cam bore, and standard deck height. I know the bronze lifter “sleeves” cost more, even though I would be using stock .842 lifters. Would bronze hold up in a street engine? Anything I am missing? Just some thoughts, I see such a block for sale here... Thanks, in advance!
