Can anyone confirm if these are good coils for a 24x swap?

Says they are from a 2004 Suburban, but the pic is kinda grainy.

 

I run those same square truck coils with my swap. Only problem your going to run into is you need the coil harness which I don't see mentioned. If I were to do it all over again I'd buy the car ls2/3/7 coil packs as they are half the size. They aren't as cheap as the truck coils but I wanted my car up and running ASAP at the time.

 

how much does it cost to go with one of these setups i never saw a price?

is it worth converting over

 

You can run those. I run the round new style truck coil with no problems. But as said I will run the ls2/3/7 coils next go around.

 

I have been running LS2 coils GM#12573190 that came with the 24X conversion kit. So far no issue whatsoever.
