If it were me, I'd go this route.

First I'd get the motor breathing as good as possible, cost without installation is about $2800 for items 1-5.

1) Head work: Porting Intake & Exhaust, Race Valve Job, Port Match Intake & Exhaust, Surface / only if needed.

2) Cams: 264/252

3) Header

4) CAI, Long Tube

5) Power Pulleys

6) Direct Port Nitrous, 35-150 WHP. Your stock internals will handle these numbers when progressively sprayed. So you could easily make more than 300 WHP, & what's even better is the WTQ output of a system like this. I'd go as far as saying that this exact setup on your 2.5L 323 would walk a stock Vette.

A DP nitrous system with all the safety devices would cost $1500-$2000.

Good luck.
I respect your knowledge on the subject of our platforms, and yes what you are recommending is a good path but if he has a decent budget I would just go twinscrew and nitrous.
