LS1 vs. S10 Rear Disc on 2nd Gen Firebird
I've read the various posts about converting to LS1 & S10/Blazer rear discs on a 2nd Gen F-Body. They both appear to be a great alternative to the factory '79-'81 WS6 Integral E-Brake set-up. My question is which set-up is easier, more readily available parts, cheaper, etc. I'm ready to begin accumulating parts, but I'm wondering which "package" is the better option.

Welcome. 1 post in two years????
I've been doing the same research. In my climate, the Blazer stuff is all rusted junk by the time those trucks make it to the yards. TX would be completely different. The LS1 stuff seems to get picked over too fast and by the time I come across one, it is partially stripped down. I am thinking I will just go with new stuff as the part prices are not too tragic on GMpartsdirect. I am leaning LS1 at this time 'cause I don't like how deep the Blazer rotor is. I doubt I am ever going to be putting 15's back on my car so size of the LS1 set up is not really a problem for me. I am planning a 13" set up for the front so I would think a 12" rear would be a better balanced set up.71 Formula, 455 Ported 96s, Crower solid cam, TKO 600, 3:73 Eaton posi. 17" 200s, RE730, 1LE brakes, Koni, Rancho adjustable bars, Hotchkis springs

I have also been wondering what the difference is. I can get either from a local yard but just don't know which is the better set up. I have been looking into doing this on my 71 chevelle 12 bolt. There is a spacer that needs to be added right?
