cam and lifter question.
 

got a 2000 tahoe with 5.3 motor is getting old but dont wanna replace just yet. running 35's on it. horrible low end power. thinking possibly a new cam to try and open her up a bit more before having a blackbear tune done. what do yall recommend.

I'm not sure bout a cam on your motor. But I suggest regearing. that will help you low end a lot. I think 4.56s will put you almost back at stock.

I agree wth the gear change since you have 35s on it.
