what inj with a 62mm

I have a set of 7x12 in my truck now and for a 62/71/12 are they to big? what injectors should I down size to if I have to?

Depends on what electronics you are planning on running. I would expect them to be hot, but not necessarily uncontrollably hot. If you are towing, I would suggest something smaller...maybe "200s" max.

Edit: Depends on what your 7x0.12s are rated at...I was assuming they are 240s, but they may not be. $.02

I have a fms and smarty. i was thinking that 200 would be better. I pull also.

They won't be as bad as you think, but a 150hp injector is ideal.

WOW 150s im way oversized then.

I ran 155's with it.

Definately oversized. I ran my Mach 5's with a 62/71/14 for a few months. I was surprised how cool it ran, never got hot till I got over 3200rpm. I would hit 1800* on a hard run. Depending on how your injectors are, they might be manageable. It is gonna be smokey though.

Yeah it's smokey. I try to keep it around 800 cause I can hit 1600 pretty quick. When I sled pull it's around 1650 with just the fms.
