'75 2F vs '85 2F

What are the main differences between the early 2F blocks? There is a hose coming from the oil pan of this '75 2F that I have. Is that normal? What is it for? Will this block still work for my swap into my 62 under the 3F head and EFI?

I can take some pictures of it if needed.

Don't know about the hose, but the '75 block is not tapped for the power steering pump mount. With all the accessories on the 3F block I think you need to find a '79 or later block.

agree with Jim. Can't think of what the hose is for...........pics please

no hose on my 75 or 76 and they are both original engines, the 77 2F on pallet has no hose either. i am wondering if you have either a F engine or just a F oilpan and that "hose" is the abandoned dipstick tube.

Crankcase venilation? I seem to recall old Chevy 6's had a hose from the oilpan...

Tonkota,

I guess you picked up the engine ok then? That is the original engine from a '75 but it was built for racing so I'm not sure what all he added. It had aftermarket PS, headers, cam, bored out, and a holley carb.
