I see many 4 and 6 cyl cars with TBI in the bone yard.

What are the chances these are the same as an L03?

i bet they are smaller. but then again they are the one injector setups so they could be the same. however, i cant imagine anybody actually knowing the answer to that question unless they have an injector flow bench and have tested them.

I found a set of injectors today from cadilac. Not sure of any color bands, but I can read the number on them, #GM61906 ... Any ideas?

Most caddy engines where 400+ cubes, so I am curious as to what injectors these are.

I figure the 2.8L single injectors are probably as big as each of the injectors on the 305's ... at least cuic inchly speaking.

I do know someone with a flow bench. So if I have to get a set cleaned, I may get a few flowed.

Mark.
