I just had two injectors fail on my 1995 Z28 after my new engine was installed.
I had an intake from a LT1 Powered Caprice cop car and used two of the injectors to replace the bad ones.
The Caprice injectors looked the same and had the same 12.0 ohm static resistance as the Z28 injectors.
The part number on the top of the 1994 Caprice injectors was different from that stamped on top of my 1995 Z28 injectors.
Are they both rated at the same 24lb/hr or did I do something very bad by using them ?
According to the Advance Auto website, the 1994 Roadmaster and the 1995 Z28 use the same exact part number for an injector.
I think I am ok, I just want confirmation.

 

If you have a neighborhood auto salvage yard they will have a book on capatibility. You may be able to call in but I had to look it up myself. I don't remember the name of the book but if you mention you need a compatibility book they will know what you are talking about.

 

If genuinely from an LT1 b-body they are 24lbs like the f-body got. Thing is the Caprice had a 4.3L V8 available the intake the same as LT1s as well as the fuel rail and it got 19lbs injectors.

 

i looked through a book and the only ones compatible were the cadillac fleetwood broughm... mabe others but there is one for you to look for.

 

I'm positive it was an LT1 from a B-Body....it was actually a Roadmaster engine (they never had 4.3 V8's...only 5.7 LT1s).
I actually had the engine with iron heads and all in my car while the new engine was built.
