does anybody know what size cam i need for a 2004 chevy silverado 5.3 and where is a good place to get a good one?

 

need a lot more info than that. the search button will help you out as there are many references with help on this subject.

what other mods do you have?
where do you want your power at?
what size stall?
emissions?
how much lope do you want?


normal would be a TR220 cam from Thunder Racing

 

Oh boy....There are an infinite number of cam profiles available and several sponsors that you can buy them from. Do a search and read the stickies and you'll find that this topic has been covered many many times.

 

28"x1.75/2 x 31%
