i suppose this is where it all starts at.
i peeked into the bottom of my block to see the damage, looks bad, but should be viable for a stroker.

i'm going to be going slow on this one :money:
its 115 during the day and dips down to a low 100 at night.. another reason progress is going to be slow.

i started the tear down, checking out what i got to work with.
i found the bearing in the oil pan, i was expecting that though.
pics to start the party with :deejay:






looks like the thrust bearing.




bottom



not too beat.


my other "ride" in the background!!! MOPAR or NO CAR!!! haha living it.


im still re-reading th other 2 threads to decide if im grinding block or end-caps.

:deejay:

it never drops below 85 degrees and its been thunderstorming lately... so 100F with 90% humidity... not conductive for wrenching...IMHO.

i still love the desert.



anyways, the motor is in parts on my table.


heads off


i didnt have the special tool for the oil pump pully. so i just left it on the crank and pulled it whole. ill get it later.




the journals almost look good.....:glum:

hey please tell me i can machine this out.....:poopoo:



I had the block squared, which means decked and line honed to true everything up, the block was hone to .001 oversize to be better able to run nitrous. There are no off the shelf oversized piston so, I am using stock 4.0L pistons which are the exact same size as the 3.5L pistons just the rod length and wrist pin location is different. The mains are stock 3.5L size with the 4.0L crank mains reduced by almost 0.200 to fit the 3.5L mains.
(quoted from your 4.0 thread http://www.dodgeintrepid.net/showthread.php?t=180952&page=3 )
can i bore the journals and use 4.0 bearings?

i swear if it wernt for bad luck id have none.:glum::glum::glum:

thanks for the PM with good news dmondeac.

so unlike dmondeac and dodgebob my 4.0 crank will be stock.

now the journals on the block will be line bored.

next step get that crank here.
get the block, heads, rockers to the machine shop
for hot tanking, trueing, milling etc.


i was looking at the exhaust headers from the nitro. think they allow more aiflow then G1 headers?

only problem with a good engine shop is they get real busy....


I dropped these off at x-mas time....

whats a fair price for a port and polish?

these guys told me getting a "bullhog" in there is 80%+ as effective and way cheaper.

I need to quiz him but he said something about a 70 degree grind somewhere behind the valve.

for $440 a head ($880 total) im wondering if I got a deal or not.

I remember paying $420 for new valves and a headjob on my 2.7

cool man, thanks.

are these intake plenums useable on a 2002?
obv from a 99-01



and I compulsively bought the 4.0 cams without thinking about the gear end.
should I return them or get the nitro/pacifica timing gears?
probably not possible to cut the ends correctly?

The plenum's is kinda a hard ball. The EGR valve opening need to exist, or be closed pending on which year your swapping too and from. Also, the High Output equipment runs on vacuum (older models have a huge assembly on the side of the motor for this) and the newer ones electric. If memory serves right, you can swap them for the electric or vacum one. But I never had much luck with the bolts cooperating.

As for the throttle bodies, I've always known them to not be compatible, due to the sensors. I have an 02-04 one kicking around with everything still. LMK.

The camshafts, well I read a lot on them as they were my go-to planned upgrade. Read a few different things and it all escapes me at the moment. I believe you can get the Nitro/Pacfica gears. But I also recall that you have to swap the tone ring?

DMONDEAC can confirm this, he's been there and done it.

I personally started planning on getting the Inherita cams, they offer three stages, shooting for the v1.2 (stage 3), but need too do some "mods" to accommodate it electronically.

thanks for confirming the plenums/TB's
ill find more. these 99-01's were "free" or included somehow I got them without paying....

and the cam's, after reading your post I bought the 3 timing gears for the 4.0L @ $99.57 shipped.

ill go scrapping for a plenum/TB then.

anyone wanting to trade plenum/TB? PM me plz.

so I got the crank back from the machine shop. the mains needed "a major cut" as the guy referred to it. haha
got a mild chamfer also.

the bearings have an oil-grove so we don't want too much...
the crank before the trim.

and after.

I like the polish on there :drool:
It almost looks like its smaller on the mains..

a first!

so it looks like the tone-ring matches the 3.5!!!
I can confirm now.



I see that minor ding to straighten...


looks like my 02 is getting ALL the 4.0L rotating assemblies!!:Rockin::worms:
the 4.0 sprocket and CAM



I'm not sure if this look is normal, but the sprocket doesn't fit without some, umm persuasion... please advise!


So TDC will be correct?

rebuilding the whole friggin thing!!

im just going to rebuild the whole dang thing from the front clip forward.



next steps involve the tranny and sub-frame.
dropped the subframe to get access to the tranny mount, undo all those bolts.

tranny will be taken to get re-built, (filters, solenoid shift pack, etc)

the rest needs major cleaning. im going to get a pressure washer and wash it.






success!!
