Title: Fury III 318 engine R & R
Post by: firedome on February 26, 2010, 12:54:25 PM
Well, I'll still need to do an R & R, but if things work out, not
for freeze plug reasons! ... I've located a 1970 318 with 18k original
miles! Out of a '70 Barracuda that had a smallblock-ectomy in favor of
a 440,  you know, the usual scenario, someone buys some
Secretary's former car and turns it into a Beast... Looks like I'm
buying the pulled engine from the guy that done did it, so rather than
screw around with freeze plugs on a 100,000 mi + engine, I'll need to
yank it and drop this one in place, which makes a lot more sense to
me.  No intake or carb, so those'll swap off'n mine, but
otherwise, it's a complete low mile long block. (http://www.moparfins.com/forum/smileys/smiley4.gif)(http://www.moparfins.com/forum/smileys/smiley4.gif)(http://www.moparfins.com/forum/smileys/smiley4.gif)

Lemme get this..
You want to install an engine you never heard run in place of one that you know runs...HHHmmm

Unless you know the guy and the car, OK, but what happened to the intake and carb? Can't imagine an 18K original mile 2bbl engine having the carb and intake sold off to make a profit, can you?
 
At the absolute absolute minimum, regasket the engine and replace the valve stem seals.
At the absolute absolute absolute minimum, replace the vavle cover gaskets and valve stem seals (they will be hard as rocks, no matter how few miles are on them).
 
And if that isn't good enough, a master rebuild kit of rod bearings, main bearings, moly rings and the rest of the parts would be just fine, roller timing chain is good insurance. If everything is as good as said, barely a hone job would be needed for an almost 40 year old aged assembled block that if run a little more often would last just as long one more time, no problem.

Steve Hobby has a 17,000 mile 360.  But, you have to buy his "virgin" to get it!  (http://www.moparfins.com/forum/smileys/smiley2.gif)

sounds like a good deal....but 1970 freeze plugs should be changed while it sits outside the car anyway.....

Ah yesssss  My time machine.  That car makes me 18 again.


 
Ed's right Rog
 
It's best you go through that engine with a fine tooth comb.  Knock the heads off and take a look.  With the heads off, do the seals.  And maybe a little porting job? (http://www.moparfins.com/forum/smileys/smiley2.gif)
 
I also agree.  Where did the carb go?  Or maybe that was a 360 4BBl?  No such thing in a Cuda.  Maaaaybe it's a 340 and nobody know it.  Now that would be a steal.  And you don't have to do a thing to the car either.  Drop er in.
 
I have the valve spring compressor

Yes, gaskets and valve seals, freeze plugs ( I have em) pull pan and
clean, but imo hone and bearing/ring/timing gear/chain would be
overkill at this point... I know this guy pretty well, I havent heard
the one in my F3 run, the derby-dude seller allegedly started it
briefly on starter fluid, but who knows what that means, all I know is
it's free.  For $150 I can't go wrong on this one, he just wants
it out of his way, planned on using it in a 50s Dodge that he now wants
a 340 iin.



Ya I know all about the Virg - I tried to pry it from him in a deal for
my '61 Belvy 361 a couple yrs ago... instead the '61 went to Texas and
became a cop car clone!

well not really. . .You should change the front and rear seal anyway.  it takes 10 minutes with the cover off, and the chains are cheap.  Double roller

Agree seals would be smart, but can't be much wear on a 18k chain - my green 71 F3 318 went over 200K on an engine that never was apart in any way! This aint a big block! My '72 T & C jumped it's chain at 95K.

True. . .but it does have the palstic gear which deteriates in time.
 
I'm going to do the one in the virgin one day. . .

If the engine is going into something that is just a beater to begin with, no big deal, worry about nothing after the intake and carb are redone (which you already have), and don't worry about the valve stem seals, front/rear seals, none of that, just get her in and enjoy it. I figure that if you do nothing to it but get her running, you can then save up the $300 for a semi premium rings, bearings, gaskets, timing set and do it in a couple years most likely.
 
Either way, look on the side of the block and verify it has something that has cast the numbers in sequence 318 or 340, 318 was not factory 4bbl back then. Kind of a shame they never did anything semi-performance with the 318 back then, it actually has more potential than a 302 Ford, and lack of parts is the only thing that keeps it from being on the 302 level.

No, it'd be silly NOT to do seals, gaskets, freeze plug, and yea,
Steve, the gear, and maybe chain, I do agree... I forgot that timing
gear was plastaaac,  some cars had fiber, even worse... especially
given that it is out, already. It's more than a beater, but I still
don't agree that doing rings, bearings, honing is desirable by any
means... I've had way too many LA small blocks, and know how just
indestuctible they are.

Also, remember that weird aluminum timing case corrosion issue Bob in
Roch had? I'm told it isn't all that unusual, so be good to check that
out.

You should put a water pump in it anyway.  Who knows with that one and the seals are 38 years old.
