Injector & spark plug Q's

[Googs]

I need to know what size my Siemens injectors are. The only number I've found on all of them is 3102 (it's molded into the side where the harness plugs into) .

Also I need some suggestions for what spark plugs I should run with my new set-up. It's Stage I block with a all forged bottom end, TA 14 bolt SI heads (no work done on them), p/p stock intake, a comp sold roller (.623/.616 lift, 240/234 dur) cam, a PT70, and fmic.

Any help would be greatly appreciated.

Thanks,
Craig

55 lb/hr low impedance. Most people start with CR43TSs or CR42TSs or Autolite 23s, tight .032 gap.

Thats interesting as if its a solid roller cam , you will have no oil pressure over 540 lift about. How are you getting this cam to work in a stage I? if its that serious you should go to 83 lbs, #3105

Before the rebuild it had around 60psi at wot. I beleave the lifter bore oiling holes have been pluged. Can't rember for sure. But the next upgrade is going to be bigger injectors, these were on it when I bought it.

Thanks for all the help,
