and the one i have i modified it to get over 400 in both h and t
(its the same kit as jds performance)

and by the way the 3400 is the same engine as the 3100 just with a larger bore

and if you go to the same power levels as me then you need to not only build the engine but also build the tranny and i got mine from domestic performance i also cryo treated the tranny and engine in full and i got a custom gearset mad so the engine would run right were the power band is i also had custom axles made

domestic performance:

and for the tranny

now go build that monster of an engine

p.s.
am going to reach for numbers in the 500's in the next month

i would advise you to use a stand alone fuel management unit as i am if you go over 300
