SO what's the deal with the 6" pulleys that LC engineering has? I'm thinking the 6" would be good for looks but will it hurt my performance? I have a cam in the truck with an intake but will I be running hotter in temp now?
If your talking about the under drive pulleys,they free up H.P.
I have them on my engine, & does not hurt performance!
However any accessory that runs off them will be spinning slower,water pump,alternator,etc.
