A coworker has a 68 Firebird that came with the 250 Sprint engine, and he has tons of stories of his younger years racing that car and beating his opponents. Said it would go as fast you had the balls to drive it. He had it up to 140 and backed it off because the front end was floating. There's a long straight road that parallels the tracks here east of town, miles of straight and that's where he got it up to 140. He still has the Sprint engine, but put a big block in the car a long time ago. It's a beauty of a car.
That'll help keep the front end planted.

Yeah, but it spins the tires too easy now, and he now shares stories of how he mainly does burnouts every time he drives it

Here are some pics of the cruise control module and servo @Chevrolado. Of course the only part of the nameplate you can’t read is the part you really want to read……

I’m not sure that this is original to the 75 Blazer as it does not match the unit shown in the factory service manual. It may be a later replacement for a failed original but it’s been around a few years.

Anyone have any idea what Amp fuse to use with the heated west coast mirrors?
the mirrors are on the truck, turned out pretty good!! they don't stick out much further than the stock style and will give much better visibility!! soon as the new gasket get here I can wrap up this little pain in the ass!!

Another 'what have you done for your square body' thing. Putting together a 'go bag' that will live by the front door where I have to see it. When I am going to drive the K20, I'll take the bag with me each time, and put it back in the hovel when I return. Some of the things have lithium batteries and when it gets to be 100+ degrees for six months of the year, I don't want to leave em in the truck subject to heat abuse.

Found an old canvas medium size tool bag. Contents will be, for now:

The M12 1/2" impact wrench/battery and 7/8" socket for lug nut stuff, a few more sizes when I obtain them
My NOCO GB50 jump pack
Multimeter
Amp clamp thingy
Lithium AAA and AA batteries
A couple LED work lights
Can of carb cleaner and brake cleaner
A Middle of Nowhere liquid transfer shaker syphon thingy

A set of wrenches, screwdrivers, sockets, hammers, pliers and stuff already live in the truck, got a beefy set of jumper cables in there as well. Also my VIAIR and Safety Seal tire plugger. Just want to keep the electronics/lithiums out of the heat

Bag is appx 10" wide, 10" tall and 20" long

Anything else you reckon would be good to keep in the sack that needs to be there I am forgetting?

One of those space blankets, fire starter, basic trauma kit, water purification straw, some basic nutrition bars and heavy gloves/coveralls. You have the truck covered, don't forget about you/passenger(s). Things happen, and you don't want you or someone bleeding out, freezing to death or similar situation going sideways for lack of basic first aid/survival. The people stuff could go into its own small bag, strapped to the truck kit.

Looks like a period-correct aftermarket cruise control.

I used to be an EMT, so the trauma stuff is covered. Little Rubbermaid tub with small tarp, gloves/coveralls, chem lights, and some Datrex food bars are already in the truck. Around here, everyone (locals) has a couple gallons of water in their vehicles, so do I. Also a beefy tow strap, a couple of soft shackles, real road flares and a set of four tire chains.

I do that also when my brain knows the answer but can't access that brain cell to spell it. The siphon hose thingy is going to be a question mark for some of the younger crowd on this site also! And considering were you live and work if it was me I'd have a go bag also along with a few more clips for the protective device thingy you carry.

There is a protective device thingy +spare copper/lead delivery capsule holders on my hip always except at bed time. Whilst driving, there is a longer, bigger thump, protective device thingy on the seat next to me with the requisite spare copper/lead delivery capsule holders...

That’s FANTASTIC, congrats!! What a great feeling to resurrect one of these trucks after so long off the road. Mine was out of commission probably 5 years, until last year. 30 years! You gotta be stoked! Gorgeous truck btw!

10 bolt housing back from powder coat and Shane wire wheeled the inside of the center to get it clean and ready to begin installing parts.

Wiped down good and installed the pinion bearing races.

Brought the second set of pinion bearings to work to hone them out to make setup bearings and a ball joint to make a tool for the sleeve.

Well, I had a flash of inspiration on the way in regarding the vacuum for the distributor advance at WOT. When using manifold vacuum, it disappears. Hmmm. What happens if you put a check valve in ?

So, I tried it. Had to reinstall the valve as I had it backwards the 1st time. :anitoof:

Interesting - it did not have the TA DA !!! effect at WOT I thought it would. It probably is a little better, and seems to be eliminating to puff of something ( raw fuel , maybe ? ) I was seeing out the tail pipe in car headlights at night.

Testing will continue.
