Greetings from Sin City. I'm planning to swap a 5.3 into my 99' 2dr Tahoe. Ive already acquired the engine and I want to do some upgrades. (Cam change, port & polish heads) I'm thinking of going with a Z06 cam and I know that it would require me to upgrade the springs and lengthen the pushrods. Can anyone tell me the correct length of the pushrods? I'm not trying to go radical because it's my daily driver. Any and all suggestions will be appreciated.. I look forward to hearing ur suggestions.
