Bottom line on the 2.3 or any engine for that matter is head work (flow numbers)cam and exhaust. Bigger valves and a ported head is key. Other things count as well. Basically the 2.3 with a stock LA3 is limited to under 300 ponies at best.
There is no free HP on a 2.3 or any engine for that matter. HP= $$$$$
