Ball and Disc or Pin style?

I seen some Lucas ball and disc 550's for $219 US and RC 550's for $269US.They both seemed like good prices especially the Lucas.Which style would you recommend and why?Thanks for the help.

Don't get 550, go dirrectly to 660/650. Odds are that you will outgrow the 550 in no time.

SBR or Kynetic has good one for sale.

Ghislain.

Ball/disk type have better atomization characteristics due to spray pattern. Look at the end of one of them and you'll notice 6 spray holes.

I have also heard ball and disc are better .That is what I just got.They are Fuel injector clinic 650 injectors they were like 307 or 315 on sale.

They fit perfect and do away with the factory hard seal system that tend to dry out and leak.

Thanks for the help.I think I'll go with the ball and disc 660'S.

pintel, keeping it simple and lasting while doing it.
