Are aluminum roller rockers worth the money for a stock 350 tbi with a full exhaust and a open element air cleaner. Does it make any noticable difference in power? Do underdrive pulleys make any noticable difference. looking for the next upgrade that is still affordable. Any recomendations would be appreciated.

 

Don't do the rockers at this point, if you need to do something the under drive pulleys is a nice start. I like the BBKs, but an intake manifold/ throttle body or a cam would give you the most noticable difference.

 

I think 1.6 Rockers would be a good idea,you will definatly feel a differnce.
