Will a 87 monte ss L69 ecm and prom work? Also is that the ecm I would want for a zz4 prom? The car is a 86 lg4 h code, it now has a 350thanks

Sould work fine, although I would look for a caprice with a carbed 350 in it. Think mid 80s police car.
Attached is the spark advance table from a stock 1988 Monte Carlo SS L69 305.

Is that spark advance pretty good? is it the same or better then the Z28 l69 curve? what about teh Lg4 curve?
Now I thinkt eh Z28 has a baro sensor and a diffrential pressure sensor?(not a map sensor) what about teh Monte SS? thanks
