Thanks. I couldnt figure out how to do that!
Yeah the Ram horns are coming off. Doug Thorleys are going back on. It's a Holley double pumper carb. Holley intake. But I think I might put my edlebrock Performer and 650 on. What would your thoughts be? And whichever I don't use I'll be able to sell atleast. same with the rest of the old block
A early engine , dipstick on the left hand side.
Must be an old race motor, the Mickey Thompson valve covers are a dead giveaway

Old school points type ignition.
Are you sure that is the numbers on the pad in front of the head? I ain't getting nothing on them numders but the numbers from you first post are coming up as either 68 327 or a 69-79 350.

68 was a large journal 327 correct? if so it would be the same block for a 327 or 350
Yes and yes, only difference would be the crank which 327 has a 3.25 stroke and a 350 has a 3.48 stroke.
That casting number is 100% a 350 block.
Im not trying to be rude but according to this it says different...

Let me correct you on that carb. Yes its a Holley, but its not a double pumper. Its a 4160 which is the same carb that the truck avenger is based off of. I'd say freshen it up a bit and install spring loaded needles and you have yourself a reliable carb that has a lot of tuneability. Thats what I used to run on my 305 and I loved it.

I saw an old picture by GM in a book one time, it was a 3970010 part# block listed for a 302-327-or 350 CI engine.
they all share a 4" bore so it isnt impossible to happen to find a 0010 327 maybe.
