pulled a motor out of a van at pic n pull, side of the van said 86, but this one has a roller cam and roller cam 4.3s started in 87 according to the rebuild kits. anyway i wanna verify this is a 87
casting# 10105867
anyone help? only thing i could find was v8 chevys

another thing is "Z" is painted/etched into the back of the heads, this means Z motor right? it actually looks like a paint pen more than anything but i know they had Z motors so i just wanna make sure :confused:

call the parts dept at your local chevy dealer with the last 8 of the vin and they can tell ya all about it.

I could be wrong here, but an S-10 with a "Z" as the 8th carachter of the vin means it is a 4.3 4x4 truck.

well the northern auto parts catalog says Car Z and Truck Z separeatly. the motor came out of a astro van and has Z on the back of the heads, i didnt get the vin# from the van but i have the computer if that helps. i dont feel like spendin 2 bux to go back to pic n pull and find out the vin cuz its probly fawked up cuz some dork already screwed with the dash.:(

is your rig gonna be driven on the street? if so you better spend that $2 and go get the vin.

have/will have a pre smog title so that shouldnt matter

is there some other reason to have the VIN# besides if it had to be smogged?

i find the vin very helpful when you need a factory only part. my .02
