Anyone know where to buy a posi rear or kit or what would fit.2 Who has or offers a overdrive kit for the turbo 350 or is the 400 a better choice for the 350/4b
Summit Racing has Positraction carriers, or check with Monzaz here on the board. The Turbo 350 is more than enough trans for a 350, if you want overdrive, the 200-4R is a popular swap
Put 3.23 or 3.42 gears in it with the 350 Trans a tci shift kit and 22-2400 convertor. I have used b&m kits and don't suggest it. The 2004r can be used too but cost Alittle to have built well. Bowtie overdrives or patc/ raptor trans are good trans builders. Too much cost for a gear vendor overdrive on a 350 trans. The 200r4 is same size as 350 with same driveshaft.just move cross member back to rear bolt holes. Don't run engine with 200r4 without trans cable installed and adjusted correct or trans can be damaged.
