I' rather have a S2 4.1 off-center block.
All accessories bolt up, no shimming crank sensors or balancers. Most S2 offcenter blocks were drilled for wet sump oiling (eliminates need for external oiling kit).
Downsides include: hard to find (off set) connecting rods, Less overall strength (no cross drilled #1 main cap). Oh yeah COST too!
Id like a used dimentionaly stable off center 4.1 with 4.000 bores
Thats just me I like a block that has been heat cycled and stable. I may have found a new 4.1 off center block and if i get it i will keep it and sell another on center block It may not be used but it will do He HE
I got me a 3.8 StageII off-center Virgin block
it has siamesed cylinders and if Im not mistaken can be bored out to over 4.0". Its obvious that it has never been assembled the lifter bore oil feed holes had not been drilled,no sign of cam bearings ever being installed no freeze plugs except 2 in the rear deck. it had spider webs in the oil gallies. I paid $2000 for it.
Very nice Block.IMO
So you have 4 bolts going through the end caps (#1 & #4) along with the crossbolts? And you have crossbolts on the center caps (#2 & #3)? I would love to see pictures of it. This is another one of those "odd" stage engines that have appeared. Is the part number still a 25500153?
My block only has crossbolts on the end caps which only have two bolts holding them down from the inside.
Your block is just like mine. I was wanting photo's of a block with 6 bolt caps. I have heard of a couple of people who have them. I wanted to see how it was done. On our blocks the center caps don't register into the side of the block. Then you have an issue of the crossbolts running into the outer splayed bolts.
