On this oil filter less than 2 miles total, on the one I replaced Heck if I know.  Ill have to check with my buddy if he has the priming tool i can borrow off him in the morning. I know the p/o  had it since 2011, not sure if the owner before him did any work to to motor so no telling how long any of it has been together or apart for that fact. At the time if the bores looked good and deck was straight i was just going to do a full top end on it with the oil pump and had it priced right about 1600, was hoping it could be done and be able to drive it and let my diesel sit until I can sell a kidney to get it fixed. Kinda making an ls swap seem more reasonable but hard to find one with all the stuff I need and everyone is way over priced. cheapest i found was a 00 with 162k for 400 bucks with accessories but no harness or anything like that

A new Melling oil pump and a little Seafoam should bring that right up to snuff.  But, I would also replace ALL of the engine seals or it may start lubricating your driveway.  Now, it's just a matter of checking the rest of the mechanicals before committing your retirement.   8)

It's difficult to know just how much you don't know until you know it.
In other words... if people learn by making mistakes, by now I should know just about everything!!!

got the heads off it today, still had cross hatching in the cylinder bores which is a plus. really debating on what top end kit i want to go with on it dont really need the higher rpm intakes all the kits come with and was kinda hoping to find one that had an oil fill provision as the valve covers i have dont have one built into them.

decided to sell the 400 small block and go with a different engine and trans combo.

     What engine/trans combo are you going with ?
#1: The easiest and most obvious solution to any problem is 99% of the time correct.
#2: There is no such thing as impossible, it just takes longer.

trans is going to be sm465 unless I can pick up a nv4500 on cl before someone else does. and for now going with a 5.3 with z06 cam from bdturnkey.
Decided that efi would be nice to have in it. plus it will be my dd while my other two trucks are getting engine work done on them and would feel a little better with the 5.3 in it if the gf takes it for a day.

well while i waited to be able to get my engine for the k5 picked up another project and got that all taken care of, but engine will be here next week, will be mated to an 08 4l70e transmission transfer case will be a np241c passenger side drop with vss (needed to shift the 4l60e series transmissions)  Diy4x Motor  mounts and competition poly mounts will be here tomorrow and fuel pump (walbro 255 external) will be here next week along with the new headers for the engine.  Diy4x shackle flip with 14 bolt with 4.10s will be going in after engine and trans are installed.  Got windstar fans mounted up to the radiator last week, did get some great parts off a 78 in the wrecking yard.   But on with what everyone wants to see the pics

new tach mounting area.



The junkyard score.   Even had the chrome for the topper on the inside and a great condition rear scuff plate.



Engine, trans, new t-case.






He had to mess with the wiring a little bit and threw in the cruise control wiring for free. so just need to buy 3 switches and figure out where to mount them and have a clean install and easy to set or adjust the cruise.

where did you get the speed sensor for the 241?

 came from either a 90-91 blazer or surburban only 2 years that have the np241c passenger drop with vss.  Luckily it was pulled but had to dig through about 9 full truck beds of t-cases to find one. now to get rid of the th400 and np208

picked up the 4l70e today and was joking around with the guy ( has a huge shop lots of custom crawlers, mudders, rockwelled and sas trucks) that i needed a 14 bolt with 4.10s and ended up having one and was able to pick it up cheaper than what pick-n-pull wanted and was already pulled for me.



and made sure it didn't go anywhere on the long freeway ride home. last thing i wanted was that thing sliding out and across the interstate.

Got the intake for the 5.3 earlier today and a seal and gasket set for the np241. 


Then just got back about 20 minutes ago from picking this up

the 208 from behind a 400 has the 32 spline input

Pretty rare.  Worth about $250 easy

well hopefully have a buyer for it and the th400 together.  got the engine out of the bed of my truck and set in the k5, gonna have to pull it back out in the a.m. to cut down the cross member slightly to allow it line up a little better, hopefully will get the trans/tcase in also before i head back out on the road.

Finally got home for 3 days and got the motor mounts set correctly, trans installed, wired, plumbed, etc etc etc. way to much got done in the last few days. and finally got the walbro 255 installed this evening before i went and spent time with the fiance and kids. just need to run a few wires, fill the coolant, trans, and tcase. and hope for the best so i can get around to the shackle flip and putting the 14 bolt in it. just sucks i just had the exhaust done before the move and now its all going to get scraped for the new  lt headers and 3 in exhaust.
