Recently picked up a 68 gmc 350/4spd 2wd lwb straight out of the barn, numbers matching all original.. spent about 30 mins got it running.. but not streetable yet..
Anyways, question.. it has a stocker Muncie SM465 .. and my question is to those who run them.. worth keeping it? I pulled mine yesterday to get at the tunnel for some cleaning up and the tranny is leaking from every where possible.. worth the rebuild? Or should I be looking at going with another tranny format? np435 or heading auto 700r4? t400 etc...
Thanks in advance
