More updates, if only for history! I can now confirm the 3K and 4K block heights differ by 10mm (ie, 4K is taller by 10mm), and have also found the sumps are not interchangable. Have ground the 3K block to accept the 4K crank and rod setup - Eased the block to clear the crank counterweights at the front and rear locating guides (as mentioned in an earlier post), and also enlarged the factory clearance reliefs on the underside of the block to clear the conrod bolts. The sump has also had a bit of modification needed. There are four small reliefs to clear the conrod bolts - these have been increased with with a ball pein hammer to clear the circulating assembly, and we also have to modify the sump's factory baffle as the crank hits it at the moment (will probably do this when we modify the sump to carry more oil).
Have also weighed the two blocks. On a set of scales with 500gram increments, the 3K block weighed 25Kgs, with the 4K block weighing the same - 25Kgs (this was however an "unwebbed" block so maybe that would alter weight in the later model blocks given the extra 10mm block height also).
On the piston front, Honda Accord (77-83) look like getting the nod! Still making a few "paper mistakes" compression wise (we only want to run 10-10.5:1), so will confirm the selection when we know for certain what head cc we will be running.
Have some goodies for sale too: 3K balanced rods and Repco pistons (will seperate the pistons), 3K twin carb setup, lots of spare general 3K/4K bits and pieces, plus other goodies if anyone is chasing something particular, let me know?!
