Man ive learned alot, 241 heads are just as good as trickflows and pacesetter headers are just as good as kooks. Wish I woulda known this before I started the build on my vette!

Not sure what clutch the stock one is, but its holding up so far. I expect to see it poop the bed soon, and me and my buddy will be doing the swap ourselves. Still not sure if I want to go with the Monster or Centerforce.

Yeah Ive heard of people doing that, but figured if Im going to do the swap, to put the extra money in to get something thats really gonna last. Your LS7 clutch hasn't slipped at all? How hard do you drive it? I ask because Ive heard they dont hold up as long as most people think, then again its prob different for everyone.

I've been told the LS7 clutch will hold up to 600hp just fine as long as its not subjected to hard launching repeatedly. And in a 400whp street car that isn't dragged a lot, an LS7 clutch will last a very very long time. Hints why I have one. My car is a street car that will rarely see a punishing launch. Another great thing about the LS7 clutch is how soft and silky smooth the clutch pedal is.
IMO, if you're going to "beat" on the car off the line consistantly, then no, do not get one. That's where a twin disc clutch deverses to be.

Plan on doing a simliar build to my z28. Leaning more towards the afr 215's though. Good to see the numbers, gives me more reason to save $$$ and I need all the help I can get
. Thanks OP.
