I ordered an underdrive set for the SB and then someone gave me a BBC engine. OH well.. I guess i will use the under drive pulleys someday..

[awbrown]

The pulleys I got were for a camaro , so I have to move the balancer back about 1 CM to get the spacing right , but for the price I am not complaining....

one of the guys on the forum has this routing, what do underdrive pulleys look like

[awbrown]

The bottom crankshaft pulley is smaller in diameter by 25% or so depending on who makes it .... some kits offer a larger alt. pulley also....

LOL, I ran into the opposite problem - the serpentine setup I got (minus the crank pulley) was for Camaro and I had (I think) the truck pulley. I scrapped mine, or it would be in the mail to you - you need part #14102091. This will move the crank pulley 1 cm closer to the engine while keeping your harmonic damper right where it's at.

Here's how I started out: I spaced the pulley out to match the serpentine setup when I was fabricating the steering:



New, longer (underdrive) pulley, with the additional 10mm I needed:

i was just curious because if i routed it different then my water pump will be turning the wrong way i got my whole set up off like a 93 sub i believe fit good every thing lined up but was missing i bolt hole in the head

Did you get the water pump from the 93 also. They are reverse flow water pumps. If you didn't you will have to get one.

thats what i was wondering too cause it gets hot fast, i believe i have the one off of it but i think it was a short pump and i needed a long one or vise versa ill check it out to make sure though water pump on tthere no is leaking out of the bypass hole at the bottom
