.484 purple shaft grind info.

Mopar cams are great cams for factory stock heads because they where designed for those castings.
Saying there old is true ,but that has nothing to do with where the valves need to be in relation to the cylinder heads and short block for the valve timing.

If you still run stock heads on your engine, you could benefit by running a purple shaft cam.
They are set up to give you the most performance possible.
I have used the .474 and .484 cam and have been very happy with the performance they gave.
I have a friend of mine who runs a .557 solid in his dart with 308 factory stock cylinder heads.
If i was to ask what cam to run, how many people would say to run a purple shaft?????
How fast do most guys with a 318 run the quarter mile in a dart on pump gas with a factory steel head??????
The car goes 11.14 in the quarter.

Is this not a great running car.
How much faster is the car going to go with a so called modern cam????

I have not met to many people going 11.14 with a 318 on the street ,let alone on pump gas with nothing more then a carb.

If the cam gives the engine what it wants,then it's profile is right where it needs to be for max performance ,modern design or old.
