hey guys im a newb but im trying to figure out y the 3.0 from ACCLAIM 1989-1993 CARAVAN 1987-1993
DAYTONA 1990-1993 DYNASTY 1988-1993 LE BARON 1990-1993 NEW YORKER 1988-1993 SHADOW 1992-1993 SPIRIT 1989-1993 SUNDANCE 1992-1993 VOYAGER 1987-1993 they are the 6g72 block but run 12 valve heads. y cant we use the stock 2.5 heads and intake and i no they bolt up to a 604/41te because thats what its bolted up to now. any clarification would be appreciated.

slap a 6g74 in her ;)

i dont want the 3.5 i like the ability of the 3.0 i have a custom turbo kit all ready made off my 2.5 that will work great with 3.0

on paper I think the short block will work...not 100% sure on the heads




CMC

the only problem i see is where the distributor is located on the block

youre talking about the 12v heads right?

what i would do, is research if the head gasket for the 6g72 12V head is the same are the 6g72 24V head...then you would roughly know that the avenger 6g73 24v head will bolt to the 6g72 12V block...



CMC

the 12v Part No: EH228T1 and the 24v Part No: EH229T2 they look about the same but it looks like there are some differences where the water jackets are

you go me ??? am trying to research if i can get the DOHC 24v heads on my SOHC 6g74... where did you get the part numbers from?



CMC

you can try looking them up on ebay or oreillyauto.com look up the year of what you r trying to do the swap and the heads your wanting to use

some else "sroufe" will probably know the answer to your problem... i just dont want to miss guide you ???




CMC

Turbo kit huh... Pics...

sorry havent had a chance to take pics i went off of some pics and diagrams off cardomain i have theose pics

post pics of your turbo set up

don't touch the 12 valves 6g72 even with a 20 foot pole

that's not the one used in the 3.0l swap and it's an old piece of junk

Alain

thanks for the info

i thought he was saying using the short block and slap the avenger heads on it... :-[


i eat paint chips




CMC

Alain I thought you didn't know what you're talking about?

I can't believe no one else figured that out.  Oh said...yes I can, I know what site this is.

yes i was going to slap the 2.5 heads on the 3.0 block whats wrong with that block

why would you put 2.5 head on the 3.0 block?

because he think that he could turn the short block of the Chrysler 3.0L 12 valves  K car/caravan engine into the equivalent of a mitsubishi made 6g72 24 valves

he doesn't realise that those 2 engines are really far appart even if they have the same basic name

Alain

the old block are 6g72 blocks so i dont see y they wont work

do what you want it's your money

 ;D

don't listen to me because according to some newbies I don't know what I'm talking about anyway

Alain

old 3.0=12 valve, overhead valve, push rods, chrysler
new 3.0=24 valve, overhead cam, mitsubishi

they are totally different engines...

heads, block, crank, rods, pistons, cams everything is different.

what is there that you don't get?

the 3.3/3.8 were pushrods
those 3.0 have a single over head cam and timing belt
I know mine will need to be done on the caravan soon  :-[

for the last time
3.0 sohc 12 valves: engine built by chrysler based on a mitsubishi design from the mid 80's and using a mix of american and japanese parts and dropped into econobox

3.0 sohc 24 valves: engine built by mitsubishi in japan designed in the mid 90 and made for performance

the blocs have 10 years of evolution between them, the pistons and rods in the chrysler are pure crap, the cranks are not the same , the oil filter could be a serious issue and several more stupid little details need to be considered

I know building an engine is fun .... i did my own design over a 5 years span .. but when you coud buy a complete mitsubishi 24 valves 3.0L for around $600-800 low mileage and good running condition I don't get why you still insist on the playing with old the chrysler made sohc block


like I said anway, I don't know what I'm talking about , so spend your money like you want

the whole "they are both 6g72" reminds me that the torqueflite 727 and the A604 are both called Ultradrive
the first one can launch a 500 hp 4500 lb muscle car and bring it in low 13 on the 1/4
the second one can launch its casing in pieces with a 140 hp engine ....

Alain

like i said newb question was told by a salvage yard that they were about the same motors just different heads thats why i asked thanks for being a dick about it tho

research before you post
