well, my 4094 and my dual fuelers are getting installed now and i am looking to the future for when my bottom end blows up for what parts i should get, my budget is $10,000 for parts ( don't know if that should be with or without install yet), i figure if my motor lasts longer than a year it will possibly be $10k in parts, if it doesn't it will be with labor , LoL !!! ANY SUGGESTIONS PLEASE AND WITH WHERE I CAN FIND THE PARTS. If i am gonna have to pull this motor out i am gonna want a solid foundation. Thanks

rods 2500
bearings 350
HS 650
MS 300
keyed cam/crank 150
cut piston ~400
balanceing 200
gaskets includign head 300

if the block and the piston are staying the same... you can re-use the ring aslo as you keep them int he same hole that will save 50 bucks a whole(400 in rings)

still under 5k wiht all that said and done

Personally I would spend the main stud money on beer...you'll get more bang for your buck :alc:

Won't get into the details about them just leave it that there are plenty of fast trucks out there without them and they aren't having any problems with cap walk.

main bearing 70 bucks
rod bearings 120
HS 550.00
rods & piston 4918.00
head gaskets and all the orings and seals and sealer 500

Guss is going to need pistons he doenst want to pull the motor and build it now, hewants to push it till it lets go.

As I said before I have 8,636.00 in machine work all the gaskets and bearings and studs and balancing.I have 11,036.00 with all the above and injectors and dual cp3's.
There is 60hr in R&R for this job and most shops charge anywere from 80.00 -105.00 hr

May I suggest that you call Eric Merchant.
last conversation I had with him was that he had fully assembled short blocks with the goodies well within your budjet.

iirc you bored the block out correct? thats half your rod and piston coat roughly

if a hone cleans up the bore and still in spec...why bore it out?

Nope std bore, I had the LBZ pistons upgraded to the LB7 cut and coated ones.and the point is Adam he;s going to run this motor till it blows so the pistons in it now will be trashed more then likely

True, but with so many hard miles and wear & tear I would think a bore job would be best. Also just wondering do you have to file fit the rings on these motors?

havent seen a ring gap spec.. would liek to know tho my gues .010-.015 is going to be were it lands

liek is if a hone cleans the said bore up to wiht in spec. why go over bore??? now if it doenst then yes go .01.02 whatever over to clean it up

and yeah he blow the motor up.. that more $$$ for a block and what ever else is ruined to get replaced if his 10k is the limit

All of the cylinder wall's I have seen on the D'maxes still have the factory cross hatch pattern. Even hard driven, 150,000 mile trucks. My opinion woulld be to not bore unless a dial-bore guage shows distortion.
