.100 is standard fare for removal from the head, assuming there has been no previous milling you could take that much off the head and the block and still not have any concerns with piston to valve clearance. Mocking a few things up or atleast measuring closely upon dissasembly will provide you with the required specs to "tailor" the desired compression ratio.

You won't break into the water jacket unless the head is a very bad casting example and I have yet to hear of a confirmed story of it happening. There is lots of meat on those heads.

If you had only a stock cam, you would not have any valve clearance problems, but with the cam you are running, you should check clearance. With nothing off the block and .10 off the head, you should still be in very safe distance. You will also remember that the head gasket will add additional clearance and if you find that you are getting very close, you may be able to select a thicker head gasket to expand the safety zone.

Kevin, .100" off the head is nowhere near water.

Lou, ya i have a 198 currently in my car i'm putting a 1964 225 in after parts and such arrive.

About the head ya i kept saying exactly what you fellas are saying to my buddies dad so i just wanted to double check my information.
Looks like while the motor was waiting in the trailer or (longer hopefully not) some water found it's was to 2 pistons despite the tarp must have forgotten it a day heres a pick look bad or what? i'm not sure i'm gonna try and turn it with a wrench or something later.

I got plenty of other pictures regarding the motor or my car just ask
alrighty so I spose i'll get the head shaved then.Whats everybody think about dumping maybe a 50 shot of juice in the motor after i get it running with the stock pistons? i don't think 50 shot would hurt it but i'm no expert like you fellas.
Thanks kevin

It's very hard to tell from the picture. Does it look like water sat in the bores or did moisture from the air just cause rust to form.

If there are no deep/ large pits in the bores, then they may clean up just fine during a regular break in cycle.

This is what I'd do if the rust just looks superficial. I would lightly sand the rusty ones with 220 grit paper and then suck the dust out with a vac. Next, I would wipe the bores with an oil soaked rag and finally, I would pour some oil in the rusty bores. I would pour in about a 1/4 cup of oil each and give it a few moments to soak into the rings.

Now turn the crank over a couple dozen times and then wipe out the crud created in the rusty bores (repeatedly if necessary) until you can better see what kind of damage/pits the rust has caused.

I have revived an engine in this way which had a few notable pits. I think even if you have a few shallow pits and they are smaller in diameter than the thickness of the top ring, that it would be worth trying to break the motor back in. This is all assuming the motor was in reasonably good condition prior to sitting.

the one with more rust has about 1/2inch of water chillin and the other one was damp and all the other cylinders feels smooth no crud in the engine head looks exellent valve train clean as a whistle had all new gaskets while taking stuff of etc. looks like new freeze plugs

A 50 shot of juice is nothing, Slantzilla uses more than that just to get out of bed in the morning.... LOL !!!!

Not sure about the bores though, I'd want to pull it apart and redo everything....but that is probably why I haven't finished my engine yet.

Do you know how long the engine sat around, I'm guessing not too long or more cylinders would have this problem. Try what Slant Ram said and/or see what others say. BTW, I bought my 74 Duster in Clearwater, FL 12 years ago. I lived over in Zepherhills for about a year.

Ya i know what ya mean about ripping it apart i've handled this myself thus far (cam degreeing i may get lost though) but this is my only car school and work so i gotta get it going soon and my dad doesn't want me to take out the pistons and all the internals for fear it will take forever since he works and i'd only do that stuff with some supervision don't wanna break anything i've been known to snap bolts now and then stupid weight training at school.For a 17 yr old i figure i got my way around a wrench nicely but some territory i perfer to tackle with 2 sets of eyes so it's kinda on his shoulders how far i can go besides that i'm on a time crunch.as for the engine my dad said they drove it on the lot maybe a few days before then i bought it brought it home sat in a trailer then got an engine lift and stand and now i've been tearing it up and cleaning.

Thanks Kevin

Go to Menard's or whatever your favorite home store is and get you a gallon og turpentine. Pour it in all the bores and let it sit overnight. Dump it out the next day and try and break the crank loose. Repeat if necesary.

I did that with a 350 Chevy and drove it for 3 years afterwards. It never did start using oil, which really surprised me since it had been stuck.

Just for grins, you may want to pull the pan and look for crud in there too. Also, you may as well check the timing chain while you're this far.

As for the hose, I have sprayed a 100 shot on a stock motor and all I've killed is a set of stock valve springs. You may want to shift lower than I do though.

You didn't say if the motor was stuck or not. The motor oil suggestion was based on a guess that it would be free or reasonably easy to free up.

I feel relieved that it was just a bit of pesky water i started some sanding put some oil in and it turned the first time i repeated alot now i can turn the crank with my hands with minimal muscle.Apparently maybe i wasn't lied to about it running it cleaned up beautiful i'll get a picture on tommorow i'm gonna pull the pan regardless it has a hole from the junkyard i'll steal my wounded motor's oil pan. Oh man it's like artwork or a thing of beauty i can turn crank with my hands with a bit of muscle and and the rust has been dominated.
(idea) electric fuel pump because it sounds cool or am i think of oil pump? anywho that would be sweet hearing the buzz before i fire it up. I gotta get my current engine out do some painting. then wait for parts and reassemble and the duster will be roaring again.
I'll get some pics up tommorow oh and i'm going to put alot of videos on youtube so theres something to watch for the fellow slant lovers.

Thanks kevin

Good to hear the rust was minimal !!! I wish I could say the same about my floorboards and trunk....

Now this looks like an improvement looks much better even in the picture.


no more rust i can turn it nicely now just gotta take my hood off and pull my current motor.Parts will be here this week so hopefully i'll mkae some good progress and get this baby fired up.If i get anything done tonight i'll update.
Looks like i'm going to need a battery tray and hold down auto part stores sell those in stock hopefully?or maybe i'll just makea tray we'll see.Oh and wish i could say the same about my floorboards too i got a nice hole in the driver side floor, it gives the car character.

OK, now I don't feel so bad. I thought I had bought the only rusty Duster in FL...LOL !!! Although, my floorboards were fine before 8 Chicago winters and a leakey windshield got to them. The trunk could be easily explaned by the previious owner who liked to go fishing....brackish water and trunk floors don't mix, lower quarters are gone too...imagine that.
