Well, most of you know my 5.3 lasted like 2 days with the D1sc pushing 12+lbs. of boost. So now its time for a new motor. Here is the new combo. Any comments and recomendations are welcome. Not sure if this is going to be enough fuel system. I was talking to one of the techs at MTI and he said that they put big inline pumps on returnless fuel systems. All I have ever seen on this site is that is a no no. Are we missing something here?

Iron 408 using new 6.0 block from GM.
Eagle crank and rods
JE SRP or Weisco pistons. 9.5:1 CR
MTI Stage 2r ls-1 heads
Either MTI or Cam Motion custom grind cam
Intake ?
Long tubes with dual 3" exhaust
60lb. Injectors
Kenny Bell Boost a Pump
Meth kit
built 4l60e
yank 3200 converter
cal-track bar
and some kind of tires

What do you think?

You may want to consider a 4l80e .

That will be your weak point with that kind of power as my trans is my weak point now. But im looking a Flt4l65e. Either that or and 80e. My 60e isnt happy anymore and likes to slip.

Yea, you will be making way too much power for your tranny I think...

why 9:5:1 ratio? You should go lower.

Since you seem to like to boost the out of your motor go with a lower CR 8.5:1 maybe.
What boost level do you plan to feed the 408? The same 4" pulley is going to make way less on a 408 vs. your 5.3

Personally I would stay with 9.5:1, the Procharger doesnt come on as early as a roots or twin screw. Need a little CR so you dont lose all of your low end.

Hmm, forgot it was centrifugal. Ok, nevermind what I said before.
