I was talking to a ford guy the other day and he said his mild 420 sbf with twin turbo makes 2300+ and he said the same cant be done with a wedge mopar. so any input or help would be greatly appreciated.
Just nod and back away, UNLESS you have a bunch of money just to prove him wrong.

I stop listening when someone (whose car is not visible) says "twin turbo".

I don't want to spend money just to prove him wrong i was seriously thinking about running 10.5 outlaw the same as him. thats when he told me mopars were ok to have back in the 60s and 70s but their not something you would want to build today and try to go fast.I was thinking of trying max ported b1 original heads and an f3 blower but i don't know if that would be enough head even with higher boost.

I don't believe the Predator heads fit a wedge block, so if your intending to use that, your stuck with B1's or Indy's....
Predator heads are made for both Hemi and Wedge blocks.

If you are building to a set of class rules that restrict cubic inch, then you have to have very good heads to compete. Only the best will do. If your goal is to just get to 2,000 hp with any size shortblock, the bigger the motor the easier and cheaper it is. The parts required still have to handle the power, but less boost/more cubes is a lot easier to work with than small cubes/huge boost numbers. The higher the boost pressure, the more the intake air temp goes up and the tougher it is to get it back to where you need it. I don't know about cost, but the turbos are the most efficient, prochargers close behind, then twin screw blowers, and at the bottom of the heap is the GMC style blower. A lot of it depends on what you like to work with. My personal favorite is a twin screw. Not the most efficient, but they have great power over the whole rpm range and no lag like some turbos will have.

My combo makes 2300 HP on 25 psi of boost . I think I got it figured out now . Last three passes were 6.832 , 6.834 , 6.780 and the car weighed 2950 at 209 to 212 for the MPH . The boost was ramped it at 2.3 seconds and this weekend I will try to have it all in at 1.4 this should give me better ET . It was doing a 4.44 to 4.46 and 168MPH in the 1/8 . Bringing boost in earlier will not make it so soggy in the front half .
You will not make this power with a Indy block , I already tried ..
As I recalled you moved the dowels out away from the cylinder bores...KB block now, correct?

Yes , they are moved away from the cylinder bores , with the 4.5 bore the o-ring gets real close to the stock dowl .
so is the kb block just thicker in this area? I was told my indy block was good for 2000+ hp

Being mid way through a Twin Turbo (4788's) fuel injected Hemi build, I can tell you this much . . . .
1) Work out your budget 2) Double the above 3) Add another 10% to the above, then you will be in the right ball park . . . .
Sure, I have heard of cheaper, more powerfull Mopar combos, but also hear a lot [Edited by Moparts - Family Friendly Site - Keep it clean] in the pub. I could of possibly gone with cheaper parts, but then it gets into a vicous cycle
I am running a KB Block
