Ok, your ECM is located behind the glove box. If you remove the glove box
liner you'll have easy access to it. AFTER unplugging the battery, remove
the ECM. There will be two access covers, one for the CALPAK, one for the
PROM. The PROM is a standard ROM chip so it'll be easy to recognize. You
need to get the P/N off of it and post it here.
Can you also look up the engine block # 0100793 to see if its a 350 I'm
working on(I hope that is the engine block # it came off the back of the
block). All I know is what the owner told me. For all I know he could be
lying to me.Thanks for all the help!
That isn't the block number (or if it is, it sure ain't in my master
listing). The block number should be just before the bellhousing on the
back of the motor, almost directly below the distributor. It will be
8-digits long and should begin with the number 1. Sometimes the last 3
digits of the block casting # are stamped into the side of the block, right
below where the heads bolt up. The last 3 digits will suffice if you can't
find the entire casting #.
I can't find my listing of PROMS for your year, sorry. Call your local
Chevy dealership and give him the P/N (the number is 192981397, the first
digits are unimportant AFAIK) and see what he comes up with.
