AFR Users Cam questions
 

I will be ordering a set of 165s. What cam should I use? I have a stock bottom end. AFR told me to use the E-303. If you reply, state your 1/4 times, and package, Thanks. Jason

What motor you plan on runnin Jason?

While they suggest using this cam,I personally would have a cam custom ground.Might be abit more money,but it'll be worth the performance.

AFR heads have weak valve springs from the factory. Thats why they recommend a cam with lifts below .500, like the e-303 with its .498.

I would recommend a comp. cam. Look through thier web page and get something around 215/220 duration @ .050 and .530 lift.

And upgrade those valve springs. You can order better springs from AFR also as an option.

i am usiong the comp cams xe274hr with my 185's..thats .555/.565, 224/232 112lsa

look at afrs site and see what cam they used on there dyno pulls for the 165's..i think they used a smaller XE series cam

The bottom is a 92. The guy only talked about clearance. I will be swapping springs.
