OK; I've read in threads here, in the Feb 2002 Hot Rod 350 article, and at
http://www.100megsfree4.com/cadillac/cad1990/cad90b.htm

that the '90 Cad Brougham used the iron-head L98...

...But does anyone know what ECM this Cad used???

Or what BIN it used???

In the text you quote it says its a TBI, the only ecms I see other then the 730 and 331 which could be TBIs are the 7747, 8747, and a 8746.

Actually the 350 was tbi. I know because i got my transmission from one of those. I know the later rwd caddys came with lt1's with iron heads.

Yup; you guys are right - the Hot Rod article says "Fuel-injected, roller-cam Chevy 350 power"...

...And the 100megsfree4 site says "cast iron cylinder heads "

For 1990, I just *assumed* it was an L98...with multi-port TPI...

It doesn't even say if it was twin-TBI (like the '84 Vette) or single...

What impressed me was "Brake horsepower: 175 @ 4200 rpm Torque: 400 lb.-ft. @ 2000 rpm"...

My 1986 Vette L98 is only rated at 230HP and 330ft/# torque...

It seemed to me that an injected Cad 350 would be a monster on the street, in the right body...

I was curious as to the BIN; but if it's TBI, it wouldn't be anything like my TPI...

This is the car I got my TBI stuff off for my camper. The ECM was a 8746. I am using the body and thr distrib but a 7747 now.
