BBC build- Don't tell the Admiral

[alldodge]

Yep that time consuming machine work is expensive

 

[Scott Danforth]

not to mention the 9-10 weeks became 5 months. going to see if I can get a discount

 

[Scott Danforth]

Just picked up the block and heads.....pictures to follow

 

[Scott Danforth]

Lost all the pics from yesterday....

Outdrive fully disassembled and plasted, ready for paint

Block on stand. Measured main and rod clearances. 0.002 on mains, just under .002 for the rods (running coated bearings).

Took everything back apart to bore notch the cylinders

 

[alldodge]

No expert as you know, but .002 on clearances I would be worried about with a high volume oil pump

 

[Scott Danforth]

talked to Johny at Yows, and that should be fine. spec is .0020-.0025 motor is capable of high RPM's. the only thing keeping the RPM's below 6300 is the cam and carb peter out.

here are some pics that I took today

 

[Scott Danforth]

Outdrive is painted....some assembly required

 

[Scott Danforth]

ok, so attaching from the phone didnt work.

Been away for a while life has brought many changes and good one's. Looks like things are evolving nicely here to,I really like what you've done. That engine should brighten your experience just a smidge so to speak. With that being said great work im a tad envious.

Thanks Tail_Gunner.

its been raining every day since I got back from vacation. couple that with grass that was 2' tall and I havent touched anything in the past 2 weeks other than fix the pics

however the admirals car will have to go outside as I want to measure cylinder bore and pistons tonight to verify the fit prior to bore notching and bolting it together.

 

[Scott Danforth]

So, finally getting back to the project

swapped use of some tools with a co-worker. he needed my spring compressor and degree wheel, i needed his bore gauge.

First, dig out the motor


then dig out the measuring tools


then start at cylinder #1, check the bore at the top, middle, bottom, and in both directions


overall the bores are good, total taper top to bottom is .0008" on one cylinder.

total out of round on one cylinder is .0006"

not bad for a production block.

cylinder bore is 4.310

piston to wall clearance is .005

now to mask off and notch the bores

total out of round on one cylinder is .0006", most .0003

not bad for a thin-wall production block.

Been a while, need to get back to this.

been doing some interior work (see link in signature) in between working on the motor and other projects.

had to do a timing belt kit for Zack's car as he heads back to college Thursday. had to wait a week for the cam sensor to come in @#$%@#$ brittle plastic



yeah, no room in the dang car



trip to dollar store for modeling clay ....




core plug installed.



bore notching



slathering the cam full of assembly lube and motor oil. like trying to hold onto a snag fish.




crank in and torqued down.

 

[Scott Danforth]

gap filed the rings yesterday (will post pics a bit later)

today, started assembling pistons, installed one of the connecting rods backwards :facepalm: had to chase a spiral loc down the driveway :facepalm:

a good mechanic can identify automotive chemicals by taste. assembly lube and brake cleaner.....yum..... a bit of blow back from cleaning a rod

went to wash out the taste, realized im out of beer. :grumpy:

done for today

Good call, we all need to know our limitations

No Title

So, here are some pics

my setup for filing rings.....not fancy..... time consuming....mind numbingly time consuming



top rings gaped to .022, 2nd rings gaped to .024, oil rings gaped to .016

Good call, we all need to know our limitations

today's motor building shirt (something dad picked up last time he was at the flea market - Not really my style however fitting for the conversation.)

and yes..... picked up more beer....

A bit of progress....then a step back....then a bit more progress

found a creative piston stop to find dead center


degreed in the cam, required borrowing a set of dial indicator points from the machinists at work


had the heads on the motor just before Irma, just about to fire up the torque wrench and I realized I did not swap the valve springs that match the cam.


so....pull heads apart, start to swap the springs and realize the umbrella seals wont fit with the dual springs I have.

off to the machine shop to get the guides cut for positive seals.

get heads back just before the hurricane, just in time to wrap in plastic and hope the house was still standing

then a trip to Wisconsin so sell my Supercharged Northstar powered Opel GT project and clean out storage

fast forward until this past weekend.

received new damper plate, new SFI flywheel and shims to finish the heads

measure installation height on the springs, shim to exact install height of 1.900" +/- 0.003

Get heads bolted on

get motor painted wrinkle red



get oil pan on

now, for the valve covers and intake.....polished or painted wrinkle black.

More pics

Shimming the head




Heads installed, rockers installed and adjusted.



Motor masked and primered


Wrinkle paint installed

 

[alldodge]

Coming along very nice. Guess the wrinkle paint makes it look like a painted rusty motor

LOL...I applied it a bit thick, more texture than I like....however live and learn........
