I was thinking about building a pump gas hemi,that has some good cubic inch,something that is not going to break the bank,that is reliable,and makes good power.
The hemi builders can chime in and give me some ideas and maybe some $$$ options.never built a hemi.I have done the 572 wedge stuff and and the high end small block stuff,but never the hemi.
would like to be over 500 cube,cast or aluminum block?decent set of flowing heads.single cast manifold,dominator,pump gas friendly,maybe even possible pro-charger one day..what would be the best head to use?would like to make 800 horsepower.

if you can fork the coin, go for the aluminum block, KB is best. Stage V heads ported from Modern Cylinder Head. I'd go with Indy's intake if hood clearance is an issue and you want to use a single carb. go for a 4.5" bore by 4.5" stroke. .650-.700 cam. Stage V rockers are best standard config gear (top fuel uses them)
Since you might go with a procharger later on, get a good rotating assembly. Most good cranks are expensive but worth it, Callie, kellog, bryant, etc. Rods: Manley pro series I-beams or Oliver Billet rods, or Childs and Albert.

I don't think you can say "hemi" and "not break the bank" in the same sentence.........
Yeah, it's got a hemi........a REAL hemi.

572 is a good combo,done this with a wedge and worked great.I like the cross-ram look,but would rather go with a single 4 set-up.hood clearence isn't a problem..I was thinking also on the stage V stuff,or just cnc'd mopar heads,by modern..I like the barton individual rocker set-up,but trying to stay away from high dollar rockers like those.the stage v stuff would probably work fine I will have to make some phone calls to get prices..

Im wanting to build a 572 HEMI myself..
I have the Callies 4.5 crank.. may go with the new world products aluminum block definately the stageV heads from Modern Cyl pump gas a must and converted Hilborns to electronic injection with stacks that will stick out of my 63 Dodge with the engine slammed back as far as I can get it without altering the firewall
I figure about 30k
You mean like this......?
that be it but with taller stacks...

[Edited by Moparts - Keep it clean] did you say 30k, is that close to $30,000?
Man oh man I got to get another job.
When things get slow I have some hemi parts and want to get some ideas of a build up, but after this thread I may need to re-think this whole hemi thing.

I agree on the 30k reply.I think you can build one lot cheaper than that.The fuel injection and stacks plus manifold,might be what spikes the price on his build... I had alittle over 20k in the 572 wedge motor I built acouple years ago,and it was packed full of good parts,jesel,callies,indy,etc..I know it was a wedge,but geeze!

I shopped around and save some money by looking for good deals. I went with a new World Iron block. Aluminum is nice, and light, but expect to be 30-40 hp down from the same Iron block So here is a run down of what I went with everything new except the pistons. -4.5 bore World block $2500 -4.5 stroke 4340 crank $700 -I beam pro rods $600 -Weisco pistons $150 slightly used from board member -DLI rockers stands etc ($1800 from board member -MP/Edelbrock head $3300 + CNC ported from Modern Cylinder head.. The flow 460cfm or so. also setup for correct springs to match my cam spec ready to go. I went with a solid flat tappet cam which was a custom deal, and some EDM Howards AMC lifters. Im just waiting from the machine shop to balance, finish bore, fit all clearances etc. I still need new Oil pump, oil pump drive, timing set, push rods, gaskets rings, and bearings which my machinist will supply upon completion of machine work. Engine will have either a MP cross ram, or Indy setup. Total price should come well under $20K so compared to the last wedge I built, the Hemi is just as cheap, although my wedge as aluminum Indy block, and the price diff between the two payed for the more expensive parts like rocker gear etc.. I have no idea for power, the heads are good enough to make 800+HP IMO. Should be right there..And be streetable as well. BTW I have pics of any and all this stuff, flow sheets etc, if you want to see anything let me know

This is what I did on my street build up,
World products block prepped by Barton, Honed to match fit the pistons, Align bored, decked, and lifter bushings installed. About $3900. 1 - Comp roller cam and lifters 2 - K1 4.5 stroke crank from Dram 3 - K1 7.0 chevy journal, width rods, .990 pin from Dram 4 - Diamond 4.5" 11 to 1 comp pistons from Dram 5 - Indy CNC ported Legend heads 6 - Milodon pan modified for single static pickup 7 - HV pump and using the pre-machined oil suction in the front of the block. 8 - Block did not require any additional clearancing for the 4.5 stroke.
A couple of things that I also will comment on. If you use a 7.0" rod, your pistons won't require an oil support rail because the .990 pin won't break into the oil ring land. I don't know what the Indy head pricing is compared to everyone else but it is worth checking into since there heads have integrated stands and they may offer a package deal with the rockers. If you choose this route, by them from a supporting vender and not direct. The K1 crank and rods are about the best budget crank and rods out there. I have had eagle and other supporting venders stuff that I won't mention so I have a good idea on comparison.

hello?where are all the hemi guys?
The is the HOT-STREET Hemi I built for the book that will be released in June (How to Build a Max-Performance Hemi". This picture shows EFI but carbs work just as as well. It's also shows coil-on-plug but a distributor would work just fine too.
This is a 572" Hemi: 800 RPM idle at 14" vacuum 700 ft lbs at 3500 RPM (curve was very flat) 725 HP at 6200. On 91 octane but it should be fine with 87 or 89, just haven't tried that yet.
World block, unported Stage-V heads.
With a hydraulic roller would be virtually maintenance free.

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.
Contact Tim at FHO. He's doing cnc'd stage v's. He has programs to get the replacement heads flowing 470cfm and his millenium heads flow almost 600cfm.

542GTX, I would have to say that mine are not quite up to the numbers I am seeing posted here! That said, I am sure that they will get the job done. I know there are differences in flow benches as well. Here is the specs.
