Drove a MONSTER Blown LT4 this weekend
The car needs more fuel above 4500 rpm but dynoed 654RWHP@4400rpm before going lean!! this was THROUGH CATS!
The current fuel setup is a sumped tank with Aeromotives second biggest pump and 50# injectors, 10an feed line with stock size return...It isnt enough!

He has 85# injectors, long tube headers with 3 inch Y, and a MASSIVE Aeromotive pump (12an line) and a Imp converter box to go on the car this weekend.
I drove the car with him (keeping it under 4500rpm) and it was one of the most violent cars I have ever driven. It broke the tires loose on a 3rd gear punch at around 3600rpm!
This car was raced once with current setup (Granny shifting it at 4800rpm and went 138mph in the 1/4!!!
Anyways look for an 850RWHP LT4 ATI powered TA soon. Sorry if I am rambling but it was such a violent car I am still amazed hahah!!

It is a 9:1 comp LT4 block 396 with AFR heads, massive cam, and all the good stuff

Theres a local guy who posts on our site (norcal-ls1.net) who has a MONSTER blown LTx setup. Heres a link to his website if you wanna check it out. I belive he makes and sells his own low impedance inj. too! http://para.noid.org/~lj/ 

That sounds like one helluva ride! About how much boost is he putting into the LT4?
