Many use SBC Cam Bearings >> http://www.chevytech.info/2c38.html

thanks that was what i needed

Is the V6 60º 3.4L info applicable to the V6 90º 4.3L engine?

From the hotsixes site-

in what order do they consider front to back (front to back or back to front

Front of engine is no.1 cyl. progressing to the rear.

im talking about bearing placement on cam bearings

#1 is the front, numbered front to back.

thank ya bubb

Looking at the Part#'s I don't see anything about the w/T or wo/T on the 60* Cam Bearings but, it's there on the 90* Bearings. Part #'s are also different.

i am looking for a diagram on the oiling system on a 4.3 i want to mak sure all holes are open so i dont have the same problem all over again

Same as SBC:

The oiling system is similar to the SBC oiling system except the left hand lifter gallery is combined w/the main oil gallery, so when you look at the front of the engine w/the timing cover and cam sprocket removed you will see two gallery plugs, not three like on the SBC. The driver side gallery is larger than the passenger side.

So the passenger side gallery feeds the passenger side lifter bores, the larger driver side gallery handles the driver side lifters and the main bearing supply. The driver side gallery is not aligned to the center of the lifter bores like the passenger side, it's offset to the outside of the bores (see below, right. This engine also has a balance shaft).

Should more be needed, the Chevy Power manual, 5th Edition has a decent drawing of the oil system, I'm not sure if the later editions do or not.
