383 vs 360 in an A 68 Cuda

That’s pretty much true what RRR said. When I did the 400 low deck in the Duster, it went in easy and was fun to drive. I even left the /6 T-bars in. I drive around on Lakewood Drag shocks on all 4 corners & S/S springs. No sway bars.

It was a blast, cheap to do. It basically was the donor car purchase, swap kit, headers plus exhaust and cutting the driveshaft.
