100% New 426 Hemi for under $10K?

[flyboy01]

i was looking through the new Mopar Muscle last night and saw something intersting.

Edelbrock Hemi aluminum heads for $2350 a pair
World 4.50 bore Hemi Block for $2750
440 Source stroker kit for $1800
Aluminum 2x4 bbl intake for $350

This allads up to $7250.

Am I right? Is it possible to build a Hemi from all new components for under $10k? Maybe even around $8500?

[bOb shingler]

NO add rocker gear, cam kit, oil pump, timing chain, carb, oil pan, pick-up, water pump and housing, distributor, wires, plugs, etc.

[sycboi]

You are still looking at $12,500 anyways.  Valvetrain alone is crazy money...

I can't imagine this stuff costing more than $1000 for the cam and rockers, the rest of the stuff should be common to the big blocks, aint it?

[NYrr496]

Hemi rocker stuff is pricey. Still, that's pretty cool that you could build a brand new engine when back in the 80's, Hemis were almost unobtanium.

[Thin White Duke]

Hemi rockers are unique to that motor.  You'll spend at least $2,000 just on rockers.  Look to spend $17,000 at the least on a hemi.

Looks like $14.2K for this one:

There's a guy on Ebay that sells a complete set of rockers for the 426 Hemi for $1000.00 dollars.  Eric

You also forgot the machine work $3-5 K .

ya deffinitly forgot a lot of things in that build .....yep new valvetrain starts at about 1800$.....what about the 300$ valve covers...plugs tubes 68$..hemi.....head bolts....110$....hemi intake bolts   40$....valve cover studs.......40$....all other bolts..200$...balancer  150$...etc etc....

[Thin White Duke]

I'd rather spend 14.2 on a killer wedge motor than a base hemi.  Those mopar crates are notorious for having problems.

[flyboy01]

Ok, I will admit that I forgot a lot of stuff, but the World block is supposed to be final finish machined, the 440source stroker kit is supposed to be balanced and ready to drop in. Edelbrock heads have a reputation of being well built with descent components.

I had no Idea that the rockers were that expensive, but even 10-11K for a 500 ci + Aluminum headed HEMI aint that bad. I am starting to get ideas in my thick little mind. I think with careful selection and planning I could build a mild 500ci + HEMI for a lot less than a crate would cost.

How about this:
$2350 Edelbrock Hemi aluminum heads for a pair w/valves & springs
$2750 World 4.50 bore Hemi Block
$1899 440 Source stroker kit
$350 Aluminum 2x4 bbl intake
$1000 Rockers , stands, pushrods, shafts.
$110 Gasket set
$239 Damper
$60 Timing chain
$220 Cam & lifters
$300 Valve Covers
$110 Head bolts
$60 Hemi plug tubes
$130 Hemi plug wires
$300 Engine Bolts
$300 Pair of edelbrock 500 cfm carbs

$9779 Total. 
I figure the rest could be swapped from a B/RB setup. What do you guys think? Is this feasable? Remember, this would be a 550 hp street engine, not an all out race motor. Theoretically, I would not need any more machining as long as all checks out, since I would be buying finish machined components.

[chryco]

Let us know how it works out .

[fasttcars]

no offense but i wouldn't want you organizing the parts build on a engine for me..cuz the thing would never run....let alone have a oiling system......and a bunch of other stuff.....{dist drive,etc,etc}.......................anyways  where did you get the info on the edel hemi heads?

[flyboy01]

So, set me straight. Why would this not run? I have never built a HEMI before, but I am under the impression that it is the same as an RB engine with a few exceptions. Why cant I use the RB distributor? Whats wrong with the oiling system, the block has all the DeTar mods done to it, so I add an HV oil pump and a pan from my existing parts collection.

Some you HEMI guys protect what you know and tell people "you cant do that", but you never share your secrets.

Fly,
I have built them and I believe Id consider what you are thinking.
You will spend a few more $$$s than 10K though. The thing is you can pick your parts and save a few $$.
Plus you get to build it. The pistons for a 4.5" bore will run $700 or more,
but Ive thought of the 440 source crank and rods before.Oh and the RB dizzy will work.

No cheap hemi out there any more. Not like the old days when gas went up and you could pick up a hemi
Cuda or RR for $2500 running and drive it home.

Flyboy,
It's not that anyone is protecting any secrets, it's just that Hemi's are a different deal.  I've built plenty of motors but jacked up my first hemi.  The valvetrain is tricky and you have to be careful with LSA and other cam specs.  The intake manifold typically requires a special torque due to the water passages at the corners.  The head gaskets and block often require alot of clearancing to get them to work.  I don't think Edelbrock makes Hemi heads right now.(I could be wrong but I haven't seen them.)  You probably will need some machining done at some point. 
$1,000 for rockers, pushrods, stands and shafts is pretty optimistic.  Good pushrods will set you back $180(Manton or Smith Bros.), Shafts $100 a piece, stands $500? and rockers at best from what you said $1,000 on ebay. I don't know if I'd trust those rockers myself.  The hemi has alot of angular torsion going in because of the heavy offset between the pushrod and roller tip.  It also will take a bit of time balancing the oil feeds to the head/rockers.  You'll need an oil pan, pump, external lines? etc.  All said and done, you'll still spend $15,000 in total to do the job right.  It's the nature of the beast.  Hemi is a 4 letter word. 

[flyboy01]

Made by Edelbrock for Mopar, I was told Edelbrock will be selling them under thier name too. Westoaks has them in stock now.



Notice the "E"     I was told that they can be ordered as Edelbrocks and should be available very soon.

[ksdartguy]

Water passages??
Not on Hemi intakes.

$1000 for rockers, stands, shafts, and pushrods from the guy on ebay. I was thinking that if I kept the cam lift resonable, that there would not be too much stress on the valvetrain. Why do I need external oil lines, stock internal oiling with an HV pump would suffice for an engine that would never see 6000 rpm, it would be built as a low rpm torque motor. Honestly, this engine would really be for show, to make my dart into a Hemi Dart lookalike. I understand that I am not selecting race components, I am selecting these parts as street/cruiser only parts that would be equal to or slightly better than stock. The only parts that even make me weary ar the rockers from ebay, but I might be willing to spend a few hundred extra for some stock components. Right now this is in the planning stages, but if I get the end of year bonus I am expecting, I might just start ordering stuff.

[lazarus]

 Just buy the good stuff and space it out over a couple years. In the end you'll have something to be proud of + if you decide to beat on it the good stuff will be there to take the pounding.

[nothingbutdarts]

I just need an alterkation for my Dart, rocker arms, shafts and pushrods to have a runner. All iron motor though!

                           

[68 HEMI GTS]

flyboy, my secret is i am using all my old 440 stuff on my hemi, milodon pan, pick-up 1/2in, timing cover, distributer, front dress. the valve gear and rocker geometry has to be set up right. i started with bare MP castings and had to do alot of work on them. i have BMS valve gear and that was another pain in its self, i had to make up custom length valves to get my geometry correct. im sure if edelbrock is making hemi heads, they've probably did the research with stock type valve gear so they shouldn't be all that hard to use. you need to spend money on good pushrods and valve train and will probably have to do some clearancing. you build a hemi like a race motor, you assemble it a few times to mock it up and check things like piston to head, piston to valve, clearances, intake fit, etc before you assemble it for real. i will tell you i thought i could put mine together cheap, but even doing all the machining and assembly my self i still have well over 10g in parts. if you want a serious engine you need the external oil system (witch i'm putting on mine this winter) 4g jessel's or T&D rockers. but for a street motor the internal oil system and a cheaper rocker system will be fine.

oh it just cuz you didn't add the oiling system into the build   so it was just a joke ya know....i didn't realize you allready had one

[flyboy01]

Well, it appears that the info I got from someone was not entirely correct. Yes, Edelbrock is making these heads, but Ma Mopar is going to be the exclusive distributor. Edelbrock will not be selling the heads direct. But I have heard that they are nice quality pieces, better than MP could have done.

[NYrr496]

They do look real nice in the pics.

[Thin White Duke]

Flyboy,
There's an article in Car Craft about building a cheap hemi.  I figure since it's just for show, can't be all that bad.

 The most recent issue of C/C?

[acpat]

flyboy it is do-able. You have to shop around but it is possible.

Yup. Sept. '08 with the Super Stocks on the cover.
