Drivetrain Upgrade Advice
Looking to upgrade the drivetrain in my 72 Lemans. I currently have a low compression 455 with small cam, Th350 with hardened internals, and a 2.73 open differential. I want to swap out the heads to a set of 6X-4 and install a proper cam along the way. Here is what I "think" I want:
1. Keep the Th 350. We used to think that they were lighter and had less parasitic drag. 2. Install a 10 bolt 3.73 posi. I like they idea of the the 8.2 because of the bolt in axles. I have seen too many cars (back in the day) on the side of the road with an axle 30 yards behind them. 3. Install a Gear Vendors overdrive. I like the idea of having the 3.73 for the occasional Saturday night at the strip, but love having a freeway flyer that buries the the spedo! So am I crazy? What are some thoughts? |
