Is there a difference between the blue tops and black tops? TIA

 

I could be wrong but I thought the black tops were 370cc and the blue tops were 450cc.

 

Seriously?

 

Black tops have a different spray pattern. Thats the only difference. I think they are newer as well, but they are def. 450's

 

they are still usable though right? planning on using them on a sohc.

 

The blacktop 450s are from the 2G dsms which are obdII (well besides 95 as far as I know) and have a dual spray pintel cap that aims the fuel at the valves.

The 1G dsms 450, which are OBDI, have the bluetop injectors, they single spray pattern.

Both will work on your car given you are running the correct injector clips for OBDI or OBDII.

you need a resistor box and obd-0 or obd-1 injector clips. you also have to hog out the large rubber ring that the injectors slide into.
