66 olds 425 info on drill hole
New person on here and i need a little help. I have a 66 olds 425 engine that has a 389244D engine and i'am looking for the place that the drill mark that might be there is. I read about it but i guess i'm looking in the wrong place so if anyone has a picture of it that would be great? Thanks

There are a couple of ways to check for cam bank angle, and if it is a Toro 425 block (probably applies to all blocks):
- Find the engine ID number/letter on the shelf behind the water pump, ahead of the intake, just above the timing chain. Now, at the RH [passenger] end of this shelf is an upright wall that runs fore-aft. This means the block is a big block.
- It should get fatter toward the front. Right near the top, in the fatter part, there should be a drill spot, at about a 45 degree angle [parallel to the even-bank head bolt holes] and just barely drilled into the wall or rib, until the diameter got to about 3/8". If that drill spot is there, then the block is almost w/o a doubt a 39-degree cam block. Every 1966 to 1967 Toro 425 and 1966 to 1967 442 400 engine I have seen so far had this drill spot and had a 39 degree cam bank angle.

Mike checked the passenger head today and it looks like a V or N 52 9583 it's hard to see and i don't see any drill mark. The guy i got the car from says the engine came out of a 66 olds 98 it has the original red paint still on it and the air cleaner is a red and orange colors with super rocket ultra high compression premium fuel.

Sorry mike forgot to tell you that they are B heads it's tough to get old. This engine runs preety good for what it is pretty much stock with just a set of headers
it' in a 68 chevelle 4 door so it' pretty much a sleeper has a posi rear and i think it has 3.55 rear gears or 3.73 not sure. Steve
