How much HP???
Trying to plan my winter project... How much HP do you thing I can expect with the following additions to my otherwise stock 94 LT1:
- AFR LT1 Heads
- Ported intake to match heads
- 1.6 RR
- 160 deg theromostat
- Coolant bypass
- Power programmer

john, looks like a great list, but while that intake is off i strongly urge you to upgrade your cam......one of the very popular ones with the LT1 folks is the GM H.O.T. cam, 218/228 duration with .525/.525 lift (w/1.6 rr's). there are other alternatives of course, but this was specifically developed for the LT1 engine/intake.
i'm not entirely sure how much more chp can be had with the whole shibang, i believe about 80 more stampeding horses on top of your 300 should be close to correct with cam & heads, and the other bells and whistles, with chip properly tuned. this alos assumes LT headers.
the LT1 guys will undoubtedly step and give alot of great advice

Dump the HYperCrap programmer, and get a real custom tune. Also you need a cam to take advantage of the ported heads. Then you will need a decent exhaust system as well. Done right its probably worth in the neighborhood of 425hp at the wheels

I am worried about passing inspection... Last I heard is as soon as you change the cam, you're asking for problems. Has anyone else in Mass been successful with running a cam and passing emissions???

I have a really nice Comp Cams custom grind camshaft that I just pulled out of my car. With ported heads and a few bolt-ons it made close to 360 rwhp, and passed emissions testing. With very little or no tuning this camshaft will pass.
I would be willing to sell this camshaft complete with springs/cups/lightweight steel retainers/locks, if you are interested.
Specs:
Duration 212/224
Lift 487/502 1.5 rockers 520/536 1.6 rockers
LSA 112
