i have a 2001 ford superduty
i have a 12v with a 62 14 htb2 a 180 pump with a 3000k gsk
now i have marine injectors from piers

truck has a brand new set of mahle .050 pistons and a fresh set of bearings in it [had a oil cooler go out and kill my 53 block ] so i replaced it with a 55 from a 02
had head shaved and a 5 angle valve job and hd valve springs installed

now for the injectors i havent seen many choices for a 12v i want to go as agressive as my prev mods will let me...

 

arent those marine injectors good enough for right now? how big are they

 

marine injectors dont match the cup of the piston very well the make a lot of smoke and a lot of heat i should have put marine pistons in for a better match

just looking for a real good 12v injector hopefully i can get toward 500hp out of this

 

Have a look at DDP. I've heard nothing but good about them.
If you're local here, you can get them from Harry.

 

hey i thought that the 53 block was only with the 24 valves?

 

Nope there are 98 12V's with #53 blocks. But, as a general rule, they dont seem to readily crack like the 24Vs.
