who ever pulled it apart many moons ago put thick grease on the bores and cyl head chambers ,the motor has definatly been rebuilt before,im hoping the heads got a bit of a rebuild as well ,i also found a little bit of lip on the bore ,the further i get into this 400 im not feeling to throw massive money at it,probly just a re builder ,im finding quite a few of these now,and when the right one comes along then do it up big,he said it came out of a f truck and it probvly did in its 2nd life as there is a pilot bearing in the crank for a manual,original was in the galaxie.

i broke one of the pistons today trying to free up a pin on the rod,all the rest were fine ,so no choice now its gunna need new pistons ,once olm8 measures it up after tanking we will see if it needs a rebore or maybe we can get out of it with just a ridgecut if anything and keep std bore size as i dont wanna get into to deep in this one,std cheap replacement pistons with the big dish will keep it in 8 to 1 region or so ,fine for a std rebuilder.

In that case, you could bump the compression up a bit of you have a set of 302 heads available.

Ok i have cleaned and oiled up some parts n bolts plus pushrods and block is ready for the machine shop i hope its good news ,also note hammer on table that is the only tool needed to fix a 400 also need to bring that manifold up to scratch by wet or some type of blasting and also the crank ,note load spreader ,would this be used on a manual as well as a flexplate ?

The manifold came up pretty good, what did you use on that?

i garantee you that manifold looks worse i think after i lightly degreased it ,i really want it to look clean and shiny,i looked on that wet blasting ,on you tube,differance between dry and wet blast.

I only got that kit because I have a Karcher already. It does a pretty good job and makes a lot less mess and noise than air blasting, and the fine sand particles once they've impacted the job are captive in the water as opposed to floating around in the air and screwing people's lungs.

Sure that would work, it won't make it shiny though. It will give a dull, "as cast" finish.

Agreed. Prime it and wheel silver paint. Easier to wipe oil stains off too....

Hey Chestnut, try this Ali cleaner, it's a phosphoric acid.

Brings up cast Ali like brand new.

Use a spray bottle, and spray it on neat or 50/50 with water.

But remember to add the acid to the water if you mix it, not the other way around or it will splatter and burn you.

 

Ali gearbox from this......

 

To this.....

 

Notice it worked best on the cast extension housing.

 

I spray it on, let it sit for 10-15 minutes then spray again and scrub with a brush.

Wash off with water.

Will come up like new.

Huston we have a problem it has a hole in the bottom of the bore maybe it can be sleeved or welded ? Other than that it came up good ,this thing definitely needs boring

[gerg 10,871]

Is it just me or has that had a sleeve already?

Sent from my CPH1920 using Tapatalk

[CHESTNUTXE 7,302]

nah thats std bore,the other pic is the lip on the block,if its just 1 sleeve the cost is not to bad and worth fixing,but lets see what he says come next week.

[CHESTNUTXE 7,302]

I'm guessing no unless they're made to also fit stroker cranks.
