Im trying to help this guy out that i just met. He bought a 96 eclipse, broken road and dont remember what else and he called me to ask me if the a 96 neon block would work. I remember hearing that its also a 420a but he said its a SOHC. Can he use this block and put on the eclipses 420a DOHC head on ther?

Qoute From Terry:

becareful with the the Neon Block being called the same. That statement is not altogether wrong but not altogether correct.

The Neon 2.0 DOHC bottom end is a direct fit for your 2gnt. Compression is the same; however the PCV system in the 95 was different. The PCV lines entered the block in the front with 2 large lines. These need to be capped off in our cars.

The Neon 2.0 SOHC bottom end is different but will work. Compression is lower, pistons are different. Again the 95 block had the different style PCV system that needs to be capped off.

All neaon heads are different and wont work without a lot of modification.

From my understanding, the sohc and the dohc is the same except for the sohc pistons don't have the extra valve guides.
Why do people resurrect this old threads, and what do you mean the sohc pistons don't have extra valve guides? Do you know what you just said? The valve guides are in the head not in the pistons, of course a dohc head has twice as many guides as the sohc because there is twice as many valves and twice as many cams!
