"refreshing" my 1997 Z28
I have 130k on my car, about 40k since I popped in an LT4 Hotcam, 1.6 rockers, tune, etc. It's been sitting for most of the last 3 years but I'm starting to get the bug to drive it again. I'm thinking about a "budget refresh" of the following.
Order a set of LE2 heads and put my existing 1.6 rockers on it. Finally installing the Hooker LTs and Mufflex y-pipe (that I bought 6 years ago). I'll then take it over to Denny at Mufflex for some "bullet catalytic converters" that he told me about years ago. I'll send my PCM out (sure wish I could remember who tuned it initially) for the !AIR and !EGR that'll come witht he LT install. I'm hoping to see 50-60 hp over the current setup (stock heads, manifold and y-pipe), does that sound reasonable?
Am I crazy for thinking of putting any kind of work into a 130k mile motor? I just don't want to, nor do I have the budget for a full rebuild, but wouldn't mind sinking 2k into this for another half second off my 1/4 mile time.
Thoughts and/or opinions?

Re: "refreshing" my 1997 Z28
Timely post!!
I'm ended up starting a big home improvement project last winter and finished that mid-summer.
I got the car on the road again for a few miles this year before the water pump gave up... so it went back into the garage and has been there under a cover for the last 6 months.
I've just recieved the final tools (fuel line disconnect set, claw puller, etc.) I need to start the project. I'll get started in the next few weeks and hopefully have it on the road for spring. I have all of the hard parts, gaskets, and tools for the following:
I'm also going to give the engine bay a "clean up" as it's quite nasty to look at/work in. I'm getting some Composite LT4 valve covers delivered today, will polish up clamps etc, just in general clean things up.
I have an SS spoiler form an '02 Z28 SS being sprayed (Mystic Teal Metallic) this week, and have decided to order a VFN "Sunoco Sytle" hood later this year. I'll post pics as I get things moving along, but don't expect quick progress! Once it's back on the road I'll go make a few pulls on the dyno to see exactly what kind of improvement I get.

- Swap stock heads for LE2s w/Bullet springs and my old crane 1.6 RR
- Port TB opening on stock intake to 58mm
- Replace stock motor mounts with poly mounts
- Replace opti with OEM replacement
- Install EWP
- Install Hooker LT Headers and Mufflex y-pipe
- Swap in PCMForLess ECM
