Ed,

I shall manually determine the resistance.  These are advertised as hi 
resistance/saturated, but I shall verify.  The old ones were low 
resistance so if these are high, I get to remove the in line resistors, 
and the multiple failure points of the connections.

My local auto electric/injector guy was kind enough to flow test my old 
injectors for grins and mentioned the slimmer injectors are usually more 
efficient. Of course, I really don't know what he means by that.  He did 
say they were a newer design.

Thanks for the comments.

Oh, btw, is anyone in the market for various old injectors....my online 
research shows the two Ford 1600cc injectors are not made anymore and 
are quite the rage and sought after for high end auto use <g>

All the best,

Chris
