120 hp - 140 hp - yet another question

[GiMLit]

Looking for internal engine specs for late 70's Chev 120 and 140 hp 4 cyl inboard engines.
Primarily I am looking for valve size, cylinder bore and stroke. Nice easy stuff.

I will soon be parts hunting so knowing specs would elimninate accidental purchases ie buying a 120 block/head vs what I am looking for 140.

Got them.
Bore just under 4 for the 120 with a stroke of 3.25.

140 has 4 inch bore and a 3.6 stroke.
