mornin junkman, it appears that anything that can be a hinderance IS!!!  yeah cheap car  is a good or I should say was a good thing!

I must say that I have been very fortunate on cheap, and cheap on gas vehicles!! before the escort I drove a 1981 datsun 210 for 3 years at a total cost of about $1200, and never paid insurance or tag (it was still in my grandpas name) it costed him almost nothing  so he didnt care to leave it that way,,,,Smile

good part about the car is I bought it and fixed the minor issues and had $850 I drove it 2 1/2 years and put 25,000 miles on and did absolutely NOTHING to it accept regular maintenance.

yeah,,,, your probably right about the gas issue, I guess If I use the old truck for another 10 years I will have gotten the good out of it anyway.  I kinda look at it like I never made a payment on it and insurance cost $25 a month and a tag is $35 a year,,,,, so the only real cost is the fuel to operate it,,,, If I leave it at the house it cost almost nothingSmile


anyway,,,,, I hope to get some pics up tonite, thanks for stoppin in fellas.

Chevelle, man you brought up a good point about operating costs and the daily grind. Its every man for himself and once you find a good runner you better stick with it til it craps! See if you can hunt up a 3800 car for cheap, you won't be disappointed once you address the inherent issues such as Dex-Cool. But I know how it is, ya gotta pick up deals where you find em. You are absolutely right about "getting the good" out of something. I'd rather put $49K into a thousand dollar car than to pay 50K for a new one simply because its new and valuable when you finish paying, instead of worn out and junk.

indeed junkman I call those "throw away cars"  and that is exactly what I do with themSmile

I never made any money buying selling cars,,,,,,, I buy the ones I like,,, I dont mind putting some cash into them (as long as it is a worthy candidate)  and drive it till its done...................

pics coming on the 454 I been slow workin on it cause other issues holding me up!!

i like the 3800 and I keep my eyes peeled for anything!! that meets my criteria for a daily driverSmile it dont matter who made it,,,, if the price is right, and it passes my inspection (I have had some crazy looks from owners from my inspections)

I wear dirty work clothes cause I know I will be crawling under checking things out.   1 hour of a thorough look over could save you a $1000 in cash or headaches!!! and I know you being a poboy like most of us know exactly what I meanSmile

a few things..

invest in some Hylomar for the head gaskets....   it will save you down the line...

when you do the carb...  knock out and thread the APT adjusting hole in the top of the carb... BE sure to NOT move the APT adjustment or use a depth micrometer and measure its height from the stop to the bowl ... so you can restore the proper height..     you will also .. want to after you get the carb together use a depth mic to measure from the top of the carb to the top of the APT .. so you can adjust it after you get the truck together... and can still restore it back to factory height..

with a cam  grind change.. you might want to adjust it for part throttle operation... it will really help with the fuel economy..  if you don't lean it out..   you might also want to see if there are any ports for oxygen sensors..  install even just for a short while .. an air fuel ratio gauge...  they are only 35 for a narrow band version..  plus a sensor...

just a few thoughts....

thanks wayne, all my Q jets are already drilled and tapped so I can adjust the APT on the fly.

I adjust it till it feels lean then back it out another 1/2 round or so, it just depends on the vehicle.

yeah I have considered  with todays fuel prices going ahead and tuning with an O2 just to obtain optimum economy.  

I guess I just figure with these heavy trucks that the 9-11 MPG that I currently get it fairly reasonable with the dishwater gas.

Ok back to the 454,,,,,,,,,,I started with cleaning the block and blowing it down with air. Followed with the pistons and crankshaft

as you can see the original pistons cleaned up well and are in great shape
DSC03622
I used an old ring and broke it in half to clean all the carbon out of the ring grooves
DSC03621


here is the pistons cleaned and ready to be installed
DSC03623

I installed the upper bearing shells and set the crank:
I do this dry to check the bearing clearances, if you *** DO NOT ROTATE THE CRANKSHAFT!  it can damage the bearings.
DSC03624

now I use plastigage to check the oil clearances.

DSC03626

I have used it for years and it works fine, it does NOT tell you if a crank is out of round so you must inspect the crank with a micrometer to check journal size and taper.

cut a small piece and lay it in the 12 O clock position on the crank
DSC03627

then install a bearing in the main cap insuring its fully seated
DSC03628

then install and torque it down, then remove  it and use the scale on the package to see what clearance you have
DSC03629

mine came in at .003 which is normal, repeat for the rest of the main bearings, being sure to clean the residue from the surfaces.  

then install the crank with assembly lube, I use this  stuff on main and rod bearings and never had any issues.
DSC03645

then,,,,,, repeat the process with the rods, I like to check them with no rings to make sure my oil clearance is good then install the rings

DSC03630

the rods came in at a worthy .0015
DSC03632

check all clearances cause this will determine if the engine will last or not!!! its time consuming, but do it anyway. its easier to fix the problem now than to start this all over again.

One thing I can see for sure, and its just like bodywork ... its a LOT easier to start with something that isn't completely used up.

Nice pics Chevelle  Cool

Hey great thread the pics are great for newbies like myself. How would you suggest cleaning my pistons? I've got a ton of carbon caked on there. Can I soak them or something?

Carb cleaner and gentle scraping works great.

Yes soak them in a bucket with some diesel fuel or degreaser over night either works great and the pistons will come out nice and clean.

I use a Stainless Steel Borillo pot scrubber to rub the loose carbon off.,. it works great.

well good progress today on the BBC,,,, I got the rotating assembly installed.
Follow along and check it out.

lets ring the pistons,,  I like to install the rings by hand only by just spiriling the rings into the grooves

start with the oil spacer ring then the oil rings:
DSC03633

DSC03634

these particular rings have dots, so dots face the top of the piston
DSC03635

the rings should fit all the way into the groove so they must be absolutely clean!!
DSC03638

then I like to just catch one end of the ring into the groove, then just slide it around carefully, DO NOT FORCE ANY OF THE RINGS, if there is a problem stop and try again. otherwise they will snap!
DSC03636

DSC03637


Then the same procedure with the top ring:
DSC03639

DSC03640

I like to install all the rings on all pistons before moving on

Theres a lot more to that than just plopping a slug in a hole, I see. That part looks time consuming, thanks for the pics. Will there be a need to check ring gaps on this build, and will you orient the gaps on each ring in a certain way?
