It makes strange noises and doesn't have a whole lot of power. The truck is a 2 tonner with the sm420 trans. I'd like to keep the stock transmission in it. I use the truck a bit around the place and figured it might be time for a replacement motor so I looked around for other sixes. Unlike Ford 300 straight sixes GM 250/292s don't grow on trees around here. V8s are much easier to come by. I figured a 305 oughta really liven things up  Anyone have any advice? | | | | | Joined: Dec 2001 Posts: 14,522 Moderator: Welcome Centre, Southern Bolters, Legion Hall | | Moderator: Welcome Centre, Southern Bolters, Legion Hall Joined: Dec 2001 Posts: 14,522 | Can't really speak about the two tonners but lots of V8's in the 1/2 tons.... including my panel. There are changes and modifications you need to make but its not such a terrible job. | | | | | Joined: Sep 2007 Posts: 461 Shop Shark | | Shop Shark Joined: Sep 2007 Posts: 461 | If ya gotta go eight, go 350. More go fast goodies & other parts available. Always thought of the 305 as a waste of time to rebuild. Good luck which ever way you go. | | |
