injector upgrade needed for cam??

That's a pretty similar cam to what bangbangskeetskeet has minus some lift and he was maxing his injectors at high rpm. He got a new fuel pump and problem solved. I will say its not apples to apples since trav has like a billion miles and I am sure the pump was well worn. Just might want to plan on some kind of upgrade since with time you will prolly need some fuel upgrades. After you get the cam you know you will want something more.

i think you need some nice 80lb injectors... and i think i might have seen some for sale on here too!

Find injectors from an 04-06 flex fuel truck. Look for square fuel rails. They're 34 pounders and will be enough, if stockers aren't.

07+ Flex fuel trucks use a 30# injector and up the fuel pressure when e-85 is used.

Will I need to change anything for those injectors? Or are they direct replacement?

Direct swap.

my truck came with 39lb'ers. Someone on hpt is selling LS3 injectors, but he is asking too much. You might be able to "unspecified religion" him down.

we do cam only swaps often with stock injectors. with your cam specs you will be fine.
and as far as the no-tune, itll run, just not well. and like everybody else has said, no WOT passes!
