Re: [Chrysler300] 64 300k camshaft part 2

It would be my opinion that you should leave the duration alone, if indeed 
it is 268, which sounds reasonable to me. The lift however, can go up to 
.509 providing you change out the valve lifter springs to some that allow 
for the additional lift without binding the coils prematurely. Actually 
going to a solid (adjustable) lifter valve train would be an even superior 
choice over the factory hydraulic setup you presently have.

Then acquire a 3.54 suregrip rear end, a performance shift kit for that 
torqueflite to tighten up the shifts and some sticky tires on the rear 
wheels and you should have a reasonably formidable ride for the "streets". 
You may not yet be able to take on a 5.0 Stang, but I bet for the first 75 
feet or so, you're going to scare the bejeezus out of him. Especially from 
a roll.
