hard to see in the pic but i'm not seeing the china wall, and those huge ports it looks like 351 4v to me? i don't think the pistons will come out the bottom, use a lathe type ridge reamer to remove the ridge! probably can rent one for cheap from a parts store
not left hand threads... impact should do the trick. i took an old sbc valve and heated it up with the torch and bent the stem 90* close to the head you stick it in a dowel hole and place the edge of the valve in a flywheel tooth to hold the crank from turning works slick! but normally i just grab the impact. the rag thing sounds legit |

There is a spring loaded flywheel turning tool we used for rotating it to remove the torque converter bolts on gm flywheels. It will definitely hold the things in place so you can apply the leverage to remove the bolts. Cheaper than an impact gun if you don't already have one.

That 400 miles ago work was probably replacing the timing chain and gears. If bits of the original nylon gears got thru the screen at the oil pump pickup, they will be in the oil galleys, which is the likely cause of oil starved bearings. Every passage needs to be cleaned out. No short cuts.

The plastic gear junk will be in the oil filter not the galleys.

more than likely they clogged the pick up screen and that caused the starvation that's what happened on my blazer's original engine to the prior owner someone before him replaced the chain but didn't clean out the pan

If you are keeping it stock, it might be worth while to bump the compression a bit with some new pistons, especially if you plan to bore it .030 over. These motors were pretty low compression from the factory. Are you planning to replace the cam or reuse? I am sure Rockatansky can chime in a few easy cheap modifications. Those D3 4V castings with the smaller valves are good heads. If your car is a factory 351C-4V car, you should consider getting a Marti report. You should have a "Q" in at the 5th digit if it was a factory 351-4V car. Here is a VIN decoder: Marti Report info is below. it will give you the history on your car and the number produced like it. |

The C4 is lighter, and less things to change on the car if you stay stock configuration. I think sticking with the Cleveland is the way to go. If the crank and rods are damaged, I vote stroker upgrade. Looks stock externally, but better torque for cruising.

in a perfect world. unfortunately some debris always gets through the pick-up screen and the filter bypass. the M code and 2V oil screen has a metal strap across the screen, covering a hole through the screen beneath the strap. when the exposed screen clogs the screen gets sucked upwards lifting away from the metal strap and anything close by gets sucked in through the hole in the screen. the Q code / performance oil pick-up does not have the 'let the crap in' screen bypass feature debris can also find it's way into bearings by splash / windage, oil getting flung around inside the engine. was there any crumbled valve stem oil seal material clogging the oil returns in the heads?

Thanks to everyone for the recent information, yes the oil pump screen is clean with no debris front the plastic gear. Sending the block out for cleaning next week, I ordered a VIN report (thanks for that source). Gonna do a complete rebuild, will keep everyone posted in the weeks to come. Yes it's a Q motor in the VIN number.....351C 4V original engine.

Also, was able to get the flywheel off using the rag in the piston, what a great method.....thanks again.

Man is that nasty. I forgot about the bypass. Hope I don't get to see that up close and personal.

So today I tore the engine down to short block condition and took it to a trusted engine rebuild shop......this entire operation started because the engine had a serious "squeak" when running. We confirmed that one of the piston connecting rod bearings was totally fried. The bearing took a large chunk out of the crankshaft so we decided a new crankshaft will be required. We also measured cylinder bore and it looks like the cylinders have already been bored out before, probably many miles ago. The machinist, being quite fussy, feels another round off boring would weaken the block. Sorry I don't have all the measurements. "No point in spending a bunch of money on a rebuild only to have to do it again down the road" says the machinist with the caliper in his hand. Good thing is the cam shaft and heads are in good condition. YEA. Next week we are going to look at a supplier who has a good crankshaft with a matching untouched block.

A machine shop can refurb your crank to factory specs if you want. I almost took a job out of high school doing fust that. Pretty awesome machinery.

the block can be bored and sleeves installed to get it back to std bore

I would keep the original block in the car myself. Cleaned up and magnafluxed then bored or sleeved.

Finding a 351C block isn't easy these days, it might be worth trying to save with sleeves. At least then it'd still be numbers matching (if that matters to you).
Did the machinist say the crank can't be ground to refurbish it?

Is your block a 4-bolt main? Those are pretty rare as well. If you go with the other block, keep what you have and clean it up. Spray paint the outside and pump some oil into all the exposed surfaces then wrap it in plastic with some dessicant bags in the lifter valley.

if it's a "Q" code it's a four bolt main, if it's a "H" code 2v cleveland it's a 2 bolt , since your going to be machining it use the 4 bolt caps and add to the 2 bolt block and have it line bored

Question; The pistons are stamped with a numbering sequence 1- 8 , is that an indication they have been repaired or replaced at one time or could that have been done at the cleveland factory.

normally the rods are stamped but my windsor wasn't but someone stamped a series of centerpunch dots on the flats of the caps i think some ford weren't originally but on the tops of the pistons will have numbers for the oversize bore if not original ... like 030, 040, 060... bearing usually have 010, 020, 030 if not std... i have seen 1-8 on factory piston tops before too

Rods were typically stamped on the pan side of the rod on the flat where the bolts are. They provide the oil for the piston skirt and only go one way as do the pistons. I haven't seen factory pistons that are numbered.
On connecting rods, I would never use a punch and mark the caps on the flat part. That is beefed up for strength and why build in weakness.
