l've got a ZZ4 crate 350 in my SC, I'm looking to get a little more naturally aspirated power out of it, without changing the cylinder heads yet. I was looking into getting a little more lift and duration out of the cam. Does anyone have any suggestions, combos, or setups that worked well for you? any numbers, or ET's would be really great. thanks a lot guys.

also, if I were to swap out the cam, would I have to change the pushrods, lifters or valve springs? the motors got fewer than 3,000 miles on it. thanks again

 

Try the LT4 HOT cam, would prolly give you another 20-25hp but not much more torque, at least according to Dyno 2000.

 

yeah lve heard about the LT4 hot cam, seems like a good cam, is there any cam out there that compares to the LT4?

 

there are plenty of other cams around but roller cams are mostly $230+ which makes the LT4 HOT cam more appealing cuz it's only $170 from GM.
