Power #’s with this setup??? Thinking about getting some LE2 heads and cam and a D1SC procharger kit. Stock bottom end. Current mods: headers, off-road pipe, borla cat-back, 3.73 gears, upgraded tongue converter (automatic car.) Obviously the car will be dyno tuned after all this is installed. My question is what kind of power numbers and 1/4 mile times do you guys think i will be getting out of this setup?

One had LE2 heads, GM hotcam, M6 tranny, 42lb injectors, headers, bolt-ons, exhaust, etc. and a ATI P600B pullied for around 5psi and a dyno tune. Made 470-something and lived for at least a couple years, but he seldom leaned on it hard and never put it on the dragstrip to my knowledge. Pretty sure the car was still running fine when he sold it years later.
Other fella had a stock longblock with some sort of Crower cam (230/235-ish), LTs, exhaust, 42lb'ers, M6, 12 bolt, and S-trim Vortech pullied for around 6psi, though it's made close to 7 on the dyno. He runs alky injection to try to keep everything safe and it's made right around 490rw. The car has seen a few dragstrip passes and has been mid-11s at 124 or so. The car sees relatively few street miles, less than a thousand per year, and he only leans on it hard occasionally and never in hot weather. Probably why it's going on 5 years with no real issues.
If you're going to put boost to a stock LT1 shortblock, you are playing with fire. If you take all precautions, run some sort of charge cooler and don't run the car hard on a regular basis, it may live a while. Of course, it could also break a ring land first time you turn it to 6k under load. You just sort of have to live with that and be ready to do a rebuild when it lets go.

Supercharge it, blow it up, new $400 stock longblock from Craigslist, repeat. I wouldn't put $1300 LE2s in harms way though, because when a piston breaks apart you'll trash the heads.
