232/262 block
-
General question. The bore on a 262 and 232 are both 3.5625 while the 232 stroked 3.875 and the 262 stroked 4.375.
Does anyone know if the blocks were the same? I would find it hard to believe they had a different block....just wouldn't make economic sense to make another casting. -
Yes, they are the same block, for any given year. Just remember that there are 'narrow' and 'wide' blocks for 232/262 as well - am not positive what year that change happened - someone with more knowledge than I will most likely followup on this - but know that the heads are not compatible (i.e., you can't put a narrow head on a wide block and vice versa).
FYI: A popular 'swap' (at the time, and to this day) is to put a 232 head on a 262 (or even a '308' I think) engine. Smaller combustion chamber, which = a higher compression ratio, which = more power... -
The above info is all wrong. The 232 engines is bored 3-9/16" with a stroke of 3-7/8" The 262 is bored 3-9/16 with a stroke of 4-3/8". Starting in 1951 they made the blocks wider because they came out with the 308 engine, bore 3-13/16" with a stroke of 4-1/2 inch. 1948 to 1950 heads will not work on engines from 1951 up. They are narrow blocks, while 51 up are wide blocks. All cylinder heads are 2 inches thick are can safely be decked 0.060 Thousands.

When you say the above do you mean all of the above....3.5625 is 3-9/16, 3.875 is 3-7/8, and 4.375 is 4-3/8. Wasn't cutting the stroke down on the 232 accomplished by changing the throw on the crank. If a 232 is an entirely different block that would be an incredible investment by Hudson to be making two different castings and then having two entirely different machining processes versus just changing the crank and the head. Please excuse my ignorance....I'm a bit new to the game. After all ignorance can be cured....only stupid is forever.

To clarify - 1948 to 1950 blocks are all identical. 1951 to 1954 blocks with 3-9/16" bores are also identical. The difference capacities are obtained by using different cranks and pistons. The 3-13/16" blocks are Hornet only.If you're stuck in a hole, stop digging.

Geoff - Aren't the 1951-1954 blocks (wide blocks) with 3-9/16" bores all either the 232 or 262? The 'odd man out' was the 308 block, with the lip at the bottom and a different, larger bore?
And, essentially - a 232 head made after 1951 will fit on any 1951-1954 block, be it 232, 262 or 308? (and a 232 head from 1948-1950 will fit on a 262 engine, from the same years?)... -
Yes, that's what I stated when I said '51-54 3-9/16 blocks are identical. 232 and 262 engines use different cranks and pistons.If you're stuck in a hole, stop digging.

Thank you Geoff - just wanted to make sure I wasn't too far gone from reality... ;-)
