Mopar Alum. 6.1 Hemi blocks - 05/31/11 08:48 PM
Is Mopar making Alum. 6.1 Hemi blocks if so does anyone know the part number?
Quote:
Does anybody have pictures of a stripped down, bare boned "RACE" HEMI
without any of the OEM asseccories?
Quote:
Just curious, who has the best price? PM me if you want to.

Finally got 'em and they're shipping.
And worth the wait, too.
They're set up to be vendor ship direct, which means it ships to your dealer direct from the machine shop in Auburn Hills, MI.
Vendor ship direct also means dealers can't see any warehouse inventory, so they might be a little nervous promising an arrival date. Tell them not to worry.
Order it, and it'll show up.
Anyway here is the spread of part numbers:
P5155507 4.125 finished bored, fully machined
P5153897 4.055 finish bored, fully machined
P5153898 semi finished machining, 4.114 bore, can be bored to 4.185
P5155630 semi finished machining "builder's special", no assembled components, allows user to finish machining to their unique requirements and aftermarket bearings if necessary
All blocks are made from casting P5153896. (P5153896AA is the most current and most often seen casting).
They're 98lbs lighter than stock. They're nice to work with, and are quite a departure from the old iron I am more accustomed to.
Here's a couple shots of an aluminum 440CI engine.

I can get one of the fully machined alum. blocks thru a friend for $2915.

Can you give details. Is he a dealer or selling it privately?
Or did it come off a truck in a dark alley? LOL
What ever it is that is a great price

Its just a friend that gets a discount at a local dealer. In case you didn't know, chrysler employees get a 25% discount on parts at dealers. Maybe you have a friend or family that is a Chrysler employee.

Are all the block the same except the one that is partially machined?
Do they just have different bores sizes?
I am trying to figure out which one to get and would like to know if the one with the smaller bore has more cylinder wall thickness.

4.185 bore block 4.250" BPE crank and you have 461 CID. That is store bought parts.
BES had two belt drive distributors on theres for Engine Masters the other year. The Jesel rocker system is $3,500. The engines can make big power just don't know how big.

Leon contact Scott Brown, he has some good info on these engines. Over 426 will require a custom crank and getting rid of the factory reluctor wheel off the crank. No big deal as you will prob just run a external crank trigger anyway. No one has really built one of these engines for nitrous, But imagine this, 426 cubes, sheetmetal intake, fuel injection, 2 foggers could be 4 stages of dry nitrous.....I know sounds pretty nice Oh yea they have been making in the 800 - 850 range already NA with these engines.....best part is they are considered Small Blocks by most racing sanctions , at least for now...LOL

I think the biggest problem ,when you get to this level , will be head gasket sealing.
Mopar should have the extra bolts on the head and block.
You would have to machine it but have them there.

I really don't think there is an oiling issue. The way these new Hemi's are oiled the 7/8 rod's are the last to get oiled. The main problems/failures come from the 5/6 rods, next the 3/4 rods getting married to the crank. Never seen a failure with the 1st oiled 1/2 or the last oiled 7/8 journals.
I take it Barton also know's there's an issue with with the exhaust rocker shafts at high rpm. Right after Indy he personally called and bought a set of our rocker shaft ties.
I have my own thought's and theories as to why the center 4 cylinder's have issue's and it ain't oil.
