mrz udp

[andrew383]

All UDP's dont have any rubber in them. They are NOT harmonic balancers. Yes its the same pulley that I have.

the ones that have the rubber are balancers tho rite??

does it have the rubber in it? is it the same one you have?

[19Cutlass94]

ohh, well the link is there, all you need to do is transfer the iginition ring, and bolt it on. and get a smaller belt.

[andrew383]

the one like you posted in post 36

[19Cutlass94]

what one do you need? What motor?

[andrew383]

Are you talking 3400, 3.4L DOHC or 3.4L GenI (Iron Heads)

The 3.4L Gen I motor just has a simple bolt on pulley. The damper sits behind the pulley. In this case you can go to any size pulley without affecting the harmonic damper.

ya thats the one i saw,but not the one i need

Thats the ASP pulley you would want if your putting one on.


and what do you mean bolt on, pressed on? Its the same EXACT thing as the FFP/mrz. The bolt at the end of the crank pressed the crank pulley/UDP/harmonic balancer on.

is that the pulley you have?the 3.4 pulleys i saw didnt press on like the one you have a pic of. does it have the rubber in it? doesnt look like it

The 3400 and 3100 timing ring is the same.

the asp one looks to be bolt on,not pressed on. is that right?http://www.aspracing.com/frame.htm

I had one on the 3500 and didn't have any problems.. oh wait...... never mind

If someone had the propper setup to vulcanize a strip of rubber in a UDP then we'd be set. FFP posted an 11 HP gain dyno sheet with theirs.

ffp went out of business i think. theres doesnt have the rubber either http://www.v6z24.com/howto/pulley

i had to swap the ring on my mrz udp. has any one swapped one over? or wound the 3400 one work??
