Don't mean to hi-jack this thread, but I have a question about underdrive pullies.


I keep hearing they're somewhat "dangerous" for the engine. If so, why?

 

well i hear that the pulley for the alternator actually with shoot otu ur engines electronics over time, coudl be a myth but idk, happened on my old 85...but pulleys yuo wont feel much, but when u put the 3 73 rear in there, u will feel liek you unleashed a 100 horse that you didnt have, but be prepared to use a little mroe gas...[:@]
