Question on 427 S.O. Casting

[RICK LAKE]

huskersnake. I am not trying to be a bad guy here but don't like this block being from and GTE car.
First off these where very rare cars. IF this is the correct block, it's worth 2-3 grant for a restore guy.
Second the block repair work on the side, is it possible this was a boat motor and it rotted out on the side of the block and was repaired. I have never seen a OEM or service block with any repair work done. The good thing is location of the repair.
The pictures where great. Did you get a number off the crankshaft? THis would help with the info. Do you remember the bore size of the cylinders before you started building it. I would also have a sonic check done. You seen to be at a good machine shop and they may already have done this.
Here's the other thing, about 15 years ago, one of the Ford mags showed how to convert a 427 center oiler block to side oiler. IF you have the main caps the rest was cake. All you needed was a long drill bit to drill out the oiling gallery along the side of the block. SCrew in freeze out plugs are easy to get. The correct ones are harder. There are different sizes but look the same. Add some allen head plugs, align bore the mains, and you have a 427 sideoiler block. YOu will need to spot surface the out side of the block for where the side bolts go through. Spacers and made from mild Steel or black pipe and cut to fit. They are more for location of caps and anything else. They help pervent main cap walk under load.
Build the motor and see where it goes. Try to be careful. Side note, with the oiling system, add limiters to the rockers of a .080" oriface and an 80# pressure spring to an HVHP oil pump. A peroiler like an accusump would also be a good idea to pump into the motor. Pervents dry startups. Make sure the camshaft has .003" or less endplay. There is a oil plug behind the distributor in the block, Drill out a .010' hole to help add more oil to the 2 gears contact. This will help extend the life of the gears. Harden oil pump drive shaft also. INfo on the crankshaft needed for more answers. Rick L. Ps what camshaft are you looking at? Hope for hydro roller or solid roller.
