ok i have a 99 4.8L with a 2001 f-body cam in it. stock push rods and springs. cam is a 479/467 207/196 with a 116 lsa.
will i need anything else to make 1.8 rr work if they will work. thnaks for the help.

 

i would put in some Z06 springs with those or maybe a better spring than that. at least a Z06 springs.

 

ok so i would be ok with 1.8's and better springs. thanks man

 

yes sir. but let me aksk a question. how much are you going to pay for the rockers. most of the time a cam can be purchaesd that will yeild more results. unless you are getting a good deal on th rockers. good luck.

 

200 bucks for the rockers.

 

ok then that makes sense.

 

so in other words, its pointless to install the rr's unless you find them cheap..

how much power could be expected?
