I appreciate the poking....It keeps me motivated.....
As far as a time frame for any particular happening......No idea.....My goal is to try and get the rear cabin weather tight before the rains hit.
My health has not been that great of late....Nothing serious....Mostly just the ravages of 70 years on the clock and having had a handful of strokes and a bout with Kidney cancer......
No biggy ya know
So just because I want to get something done does not mean it will happen.....
I try to set a goal of some certain thing that needs doing....Even if it is only figuring out wiring or sourcing some needed items.
I hate letting a day go by without doing something......but that happens more than I would like......
There is still a lot of work to do....
Finish the engine (Have most of the parts)
I need to rebuild the TH350 tranny.....These are simple to do.....been through many back in the day
Just one step at a time.
I want to get the body stuff done and pretty much complete so I can get them off the chassis and set aside.
Then go after the mechanical stuff.
The OC12 is complete (Center section) The axle tubes need to go on and the axle bearings replaced and the axles installed
I have left these off simply to save space in the shop......
Drive shaft parts are all here.....The long section is rebuilt (The long section has two double cardan joints with the bolt flange at the rear end)
The short front section needs to be cut to length and the center support bearing bracket put into the tub.........This is pretty easy stuff.....can wait until the body is back off and out of the way.....
The "Double Double" arrangement is a sweet way to negate the worries about driveshaft angles ....At least to a great degree...
The rear end has to go where it has to go and the engine and tranny has to set where it is.......
So having two CV joints on the main section will keep things happy......I do not know at this time exactly what the angles on the shafts are....but the are very shallow......The main thing is that there is not anything weird like a compound angle or ???? to fight with.....
The original setup from Thiokol was a simple shaft with two single cardan joints.......
Given the high speed that this shaft must spin even at the fairly slow pace the cat moves (Maybe 12-15 mph) I wanted to be sure that we don't get bad vibes.....
The shaft I am using came from an S10 EXTREME.....(Long bed extended cab)
These shafts were notorious for issues.....This said..The issue was that the centering ball in the joints need to be greased, and folks would not do it.
Once the ball wears out the shafts vibrate bad
The center ball takes a needle greaser to get lube into it.....Most lube shops and or home mechanics do not understand.....
The standard joints are non grease types ...so folks assume they do not need to do anything.....Hence the center ball gets left to dry out and go away.....
I replaced all the parts with serviceable stuff...Zirks on all points.
The Double Double adds a bit of weight.....But likely no more than the original shaft that was in the beast..
The factory shaft was 1410 joints on a big tube..
The super low gears in the cat really reduces the torque load on the shaft.....So I decided to use the S10 EXTREME unit
Also ...again, all easy to get parts.-
Trying really hard to keep with off the shelf and easy to find parts.......
The engine is nothing more than assembly work on the short block.....
The Vortec heads need to go to the milling machine and get the STEAM HOLES between the cylinders drilled through the fire deck and into the water jacket.
400 SBC have Siamese cylinders with no water between them....The areas at the top between the cylinders will form steam pockets if the holes are not drilled......Factor 400 heads have the holes.......Also the factory heads on the 400 were junk.....
The Vortec heads I scared up are in nice shape......Off of a 1998 3500 truck.....
Still need a carburetor type intake manifold for that fits the vortec heads.....Just have not popped the $$ for one yet is all.....
And then of course are the day to day things....Living.....That always seems to get in the way of CAT TIME...
