Ted, you had mentioned in an earlier post about  possibly sleeving a 312 block, don't know what sleeves cost, but this seems like a solution to me. I have a 292 block that was a Fred Jones rebuild that has 8 sleeves and is std bore. This engine came from a 63 F600 farm truck and ran for years with no problems.

Ted:

The first blocks I did, I bored right through the seal area with the cap in place.  That left a shallower groove, and I had trouble making rope seals work.  The latest one is in the race car now, I did not bore the seal area in the block.  I turned the crank seal area down to 292 size and a stock 292 neoprene seal was installed.  Two seasons on the engine, no leak yet.  Maybe if I had turned the cranks down in the first ones the seal would have had a better chance.  Modern rope seals are junk anyway.

John, I’ve talked to a local shop about align boring a 292 so that capability is here.  Question I have for you is do you leave the 292 main seal size intact or take it out to 312?.  I’ll have to look at the blocks in the rear main seal area but I can envision some issues in taking the main seal size out larger.  If I go the align boring route, then I’d prefer to have the block align bored to within 0.003” of where it needs to be and then get it align honed to the finished size.

Billy, I cut and paste the information over to Excel and was able to read the left side of the table.  Beats me why it pasted in the way it did unless it was pasted without first converting it to a picture format.  But I gotta love your organization just the same, makes it easy to see what you have.  If using a 312 block, I’m needing one that will clean up at a maximum of 3.814” which means only 0.007” per side is actually being removed on an unworn block.  See what you've got that will fit this criteria.  When I come across a block I think is suitable, I’ll rough bore and hone to 3.811” to insure it is in a position to clean up at the finished bore size.

Ted if this works copying and pasting, These are the blocks and heads I have kicking around my house, I have probably half a dozen more blocks and sets of heads in my brothers barn about 15 minutes from me, I'll have to get up there and inventory the stuff.

For some reason the left side of the table will not show up but maybe you know a trick on your end to view it.

Ted;

Let me know if the 312 blocks or Frank's boat blocks (I did NOT say "anchors") don't work out and I'll take my standard 312 apart and check it.  It's stored in a barn with no heads, rust is in the cylinders.  Is align boring available to you in your area.  I know most shops align hone, would probably be reluctant to take 1/8" out with a hone.

Royce.  Did you get my email regarding camshaft specifications for the EMC engine?  If not, just let me know and I'll resend.  Thanks, Ted.

Frank.  Take a look at that Crusader block and see if it would clean up at 0.015" over.  Also check to see if it has the additional main webbing or reinforcing in the main area as is seen on the C2AE-B blocks.  I hope to know the cylinder bore condition of the remainder of the 312 engines I can put my hands on by the end of this upcoming week.  Gotta pull heads on some of them to check them out.

Ted,

       I have a later Crusader block (C1 or 2) which I think is standard. I'll take a look if you don't find one.
