Some have managed to survive not having rear end problems, but that posi trac sure does make it handle better on the launches..... Good luck and have fun with it.
What are the options for better intake manifolds? SL55's? These 55k cars did not come with posi-traction?
Thanks, Mark
PS: Not interested in revingnany motor,past it's safe Zone. just thought with the additional flow' and 3psi extra that the,motor might make,peak power past the stock motor's 6200rpm is all.
