To the top

 

I got a 224/224 cam would i have any issues if i install it in a stock 5.3 i just want it for the sound

 

I have 226 230. 575 600 it hits pistons had to change them

 

I would wager there are newer and better options than those discussed in this ancient thread.

A viable topic, but one that deserves a fresh start in a new thread.
