World block, Scat 4.5" crank, 9.5: pistons, etc...
Typical rotating assembly - nothing trick or expensive.

The only "special stuff" to the basic motor was:
* A very smooth plateau-hone using a gapless top ring and a "hooked groove" second. (Yes - the hone was more expensive to do). Pistons install with a "seating powder" not WD40 or oil.
* Cam specs are different, but not any more expensive.
* Heads only had a valve job.
* KB rocker stands and Comp valve train.
* Used a new "reverse flow" water pump from Meziere. (Had to drill air-bleed holes in the heads to use reverse flow).

This rings seated in 10 minutes and have produced very good results for me for a street engine. Other engines I've built with these rings really keep the oil clean after many miles. Leak down is nil.

The cam has a very wide lobe separation (114-116) with nominal lift (.600). Durations are 240-ish intake and 250-ish exhaust (@ .050). This is what gives this engine such good manners from idle on.

You can go really inexpensive if 800 is really where you want to be. Going forced will pile the dollars on right along with the power. To save every buck you can here's what I'd do.

Scat 4.5 crank
H beam 7.1 rod
11.5:1 piston from any of the big companies with a standard 1/16 1/16 3/16 moly ring package
SV replacement head with basic port work (bowls-port entry stuff) stainless valves
Indy roller rockers on steel stands
mega, or world block Iron. Move the pickup over and use 5/8 pickup, keep it internal for cost.
solid flat tappet with chain drive
Indy small plenum 4500 single 4
OTB holley 1050
steel tray and milodon pan

It'll make over 800 and be about as cheap as you can go. Going forced means throw all that out the window and get ready to get off the hip

My build is similar to others here. 572"

World aluminum block
Block honed and prepped @ FHO for CP 10.5 pistons
Diamond rings
Stage V replacement heads CNC ported @ MCH
Stage V rockers T&D shafts, Hi Tech stands
K1 crank
K1 7.100 rods
Comp solid FT Nitrided and using Howard's EDM lifters
.620" .630" 258* and 263* @ .050 108 LSA
Milodon dual swinging pu pan HV pump
MP cross ram with FHO lids or Indy single intake
Probably 2 770 SS carbs
MP tach drive dist.
Chain drive for cam
MP water pump assy

I am not sure what HP level to expect.

Hemi Allstate, Just wondering what the stage v cnced heads flowed after they were ported? Planning on building a 604ci hemi for my GTX and not sure which heads to buy.

I also used the Stage-V replacement heads. With only a good valve job and smoothing the seat areas (no additional porting) they flowed 388 (int)and 277 (exh), measured at .700 lift.

WOW.....that's about what i was hoping for.Thanks

Thanks Hemi Allstate, Thats roughly what i would be hoping for. my motor will be a pump gas 604ci.

New MP/Edelbrock castings

I got a buddie that just bought in a package deal, a fresh 572 with all the goodies long block, with virgin Mopar heads separete, but the long block is very nice.. He maybe looking to broom !!
