Thread: under drive pulleys

in the middle of my engine build and wanted pulleys....so i got on ebay and found a set of UR pulleys, alt, crank, water pump. price was $209

then alittle farther down the page i see a set of all 4 for $179. they were OBX pulleys so i bought them since i trying to build my engine as cheap as humanly possible. ill be compairing them (size wise) to the UR pulleys jensen has. if i can convince jensen to pull his crank pully off ill compair the weight with a "small scale" my buddy has

my thoughts exactly.

$70 crank pulleys

I'm wondering if they have timing marks on them? I also wonder if they are balanced correctly. Let me know, as i was going to buy the 4 piece UR set soon.

Interested aswell. As im close to buying UR pulleys.

IIRC, about a year ago, they DID NOT have timing marks. I ended up just buying the UR 2-piece set, I didnt want to take the chance with that cheapo brand. A header is one thing........

So you'd have to set your timing before, then install this pulley, and hope you don't have to set your timing again? That's kinda crappy.

just mark them after you take your crank pulley off, compare radially... and put some small notches in them with an etcher, or knife.

Hmm, i guess you could do that.
