Hello all I just picked up a 91 GMC sierra as a project. The truck was originally a 4.3 five speed and the previous owner put in a 5.7. With the nv3500 transmission the truck is pretty fun but it really needs an update. So over the winter I will be fixing small things and working on gathering the cash to do either a 5.3 or 6.0 swap. Should be able to find all my information on this page. Thanks in advance
