317 heads on a 5.3

[Duntz]

i dont reccomend you putting 317's on 5.3 espeacilly if your close to stock. you will lose compression espeacilly torque, since ur truck is 4X4 torque is what you need.

yout stock head's are at 62CC and 317s are 72CC.

my best bet would be a cam 212/218 - 56X,58X lift on a 114 lsa. great DD cam works well with stock stall,starts pulling at low rpm and great torque cam.

Thanks for the heads up guys.

Would the Thunder Racing Cheatr cam be a good cam to run, specs: 214/230 .601/.575 117 LSA or stick to something more like what you recommended? I found a cam close to what you told with lower lift though on Texas Speed.
