what does a stock 95 z28 have as far as roller rockers? if i were to install the gm847 can i run with stock RR ?

 

I wouldnt. Enough spring pressure to break / bend them

 

Update on my install. Car is running pretty well considering that I'm running with a CC305 based tune. I'm definitely in the "Wilt Flowers" by the roadside category right now. If I stand behind the car for very long my eyes start watering, and that isn't an exaggeration. I need a tune. Of course now I'm thinking I'll wait for that because I have a 383 in the works, and don't really want to pay again, but I'll probably work a deal with Alvin. This cam really pulls and wakes up at about 3500 and doesn't seem to want to stop until I'm bouncing off of my rev limiter which is set too low by the way, (need to get that tuned as well). I'm hoping to get to Silver Dollar on the 28th for the F-body Shootout, where I can see if the work was worthwhile.
