I have already read lots of good information on this sight. I haven't seen any 411 on 6 lug disc brakes. Is there anyway to convert the original axle housing?
I am planning to change the 228 engine to a 302.
Put a dual master cylinder w/disc brakes up front.
replace 3 speed with 5 speed (nv 4500)open driveline
use some axle configuration with a 3.55 or 3.73 ratios
I just want to know before I commit. | | | | | Joined: Jul 2005 Posts: 595 Shop Shark | | Shop Shark Joined: Jul 2005 Posts: 595 | give mark at www.scarebird.com a try.if i do recall they use blazer 73-87 rotors.i believe that rotor will work for front and rear. give mark a visit on his website. good luck | | |
