I picked up a 73 Duster that was supposed to be a 440 big block but ended up being a 65 361bb. I was a little pissed at first but got over it because it still runs and drives fine has the 727 and 8 3/4 rear decent interior and body. But my issues have started now. I installed a kick down cable because it would shift to 3rd instantly with the ghetto setup it had. Have to adjust it a little more but now it down shifts when I hit the gas. And I have to adjust the idle to get the correct vaccum for the brakes.
The biggest problem is it seems way to slow for having even the 361bb in it. Tried to launch it but the brakes won’t hold it at all and the tach isn’t working right so have to fix it to know the exact RPM but I go WOT and it just feels like a dog and seems like it’s just going super slow. Not sure what the power output is for a 361bb but can’t be that low. Like it just feels like it’s a 18second car honestly.
