I don't like using hammers and such to 'clearance' oil pans for cranks
.
Honestly.
The 2.3 use to be a huge issue, now pistons are shelf stock, granted 2.0 pistons are easier to find, and 2.4 pistons are easy, but the 2.3 pistons are becoming more of a commonly stocked item by the major manafacture.
Rod ratio is the same as a 2.4 obviously, I just don't like the idea of grinding main caps, denting oil pans, and grinding block material.
Other than that, it is a cheaper option versus a true 2.4 4g64, but 4g64's are becoming more of a rariety.
I dunno, imho its 'better' to go with a block and crank made for each other (from the factory).
a year ago: 2.3's sucked the big one
now: easier to work with, fairly good option.
So I guess, they are even, with the cheapness option going to the 4g63 based 2.3 or '2.4' (pending overbore).
