Just remember, the neon is NOT a 420a
The block is the same (2.0), but it is not a 420a casting, and the head is not at all the same. I don't really mess with 2.0's though, the 2.4 is just such a torque monster compared to it. I was making almost 400 ft/lb on pump gas, where on a 2.0, I could string it out a little bit more, but I would make probably 75 ft/lb less.
