yes the 243 makes 15hp more but if your on a budget like I am send your 241s to AI and save yourself $400.
If you want to wait to see my results my car will be tuned and dyno'd early spring.
Here's some results I found in search, I wouldn't expect the PRC 5.3s/243s to make much higher than 5rwhp more if any more power.
