508 or 509 Purple Shaft cam

for some people .001 can make the difference.......lol

Difference between a **** career and being just a dumb dick... LOL

Please get over the .001 difference people call these cams.

I find the 114 LSA cam they made for these to be a complete turd.

Even at 10.5 compression, I wouldn't be afraid to install a 108LSA .508-.509 cam at 100-104 ICL... if you want some more low end grunt. Just make sure you have Valve to Piston clearance. Ignition timing will make a HUGE difference in how the cam reacts/runs.
