Rims won't fit on rear with drums.
Working at a shop that sells tires we see wheel interference problems almost daily. Know the horse has left the barnyard but always check fit first. Modern production tries to consolidate part numbers. Is it possible drum is not the same as OEM? Although not recommended spacers may be the only...- fast 99

Radiator recommendations for 6.6l 400
An aluminum core replacement will work fine provided the fan, clutch, and shroud are intact, correct and working. Don't get why people remove the stat. Coolant will move too fast for heat transfer. Even most race cars use a stat or restrictor. Install a 180 or 190 high quality stat. Economy...- fast 99

Help with diagnosis and repair
If automatic, power braking many times will help with diagnosis. Load engine to 1/8th - 1/4 throttle, watch for bubbles in radiator. In the shop we use a pressure tester and watch for pressure increase. Can't give exact numbers it's one of those experience tests but I have seen 5 psi increase in...- fast 99

2 post shop lift
Think I have seen those in shops that work on heavier duty trucks. Another one is rail hoist. One in ground cylinder, beams running length wise. Designed for vehicles with solid axles both ends. Probably made for 40's cars. -

I just tossed it out, many don't know the brand. Purchased a 15k when I had my own business. A little bit of an overkill for home use. Back then cost was 10k probably a lot more today. -

A shop I worked at 15 years ago had 2 post inground hydraulic hoists. Used a gear arrangement that kept them timed side to side. Similar to 2 post above ground other than not having a big vertical beam in the way. They were completely worn out and totally dangerous, no arm locks. Hydraulics... -
engine performance Issues,
Yes, go back and double check tune-up, especially firing order. Exhaust leak can cause popping into exhaust, but you said it runs poor. Could be a valve problem, bad distributor cap, vacuum leak, base tune up, ect. Check vacuum is it steady? What is the reading?- fast 99

2 post shop lift
The old single post got in the way for some undercar work and didn't work well if a transfer case was hanging down. 4 post are good for that but the added height of the rails makes removing motors an almost chain fall affair. The best all round is 2 post. Yes, have to be more deliberate with... -

2 post with crew cab will work. Hoist needs to be high quality. We raise them all day on a Bend Pak. For added stability quite often we add a stand to the rear. Just be sure to remove it before lowering the truck. Have seen that done, it usually isn't pretty. A 4 post will also work but to... -

Help locating shift indicator part
tried, did find another one but they want $130. That's just nuts. Think I would try soldering on a cable on it and use a small crimp tube for the loop. May be try Ace hdwr for a crimp piece of some sort. Looks like a fairly easy piece for someone to reproduce. LMC has the assembly for $30... -

Engine stabilizer bar
That's an expensive part for mass production. If not needed GM would have eliminated it. Be willing to bet they had case fractures during testing.- fast 99

Smog Pumps on 1986 K20 Suburban
No you won't notice any difference in power provided it isn't a feedback system [O2 sensor]. I question why take any of it off? What are you attempting to accomplish? And yes a stationary pump will seize in a relatively short time and without air circulating the control valves may burn up...- fast 99

Rattle noise from A/C compressor
While I agree some techs today are parts changers, think your being a little over critical. If the bolt was missing, can see where you have a point but the washer? Assembly manuals aren't something a tech today looks at or even has available, especially on a 40-year-old vehicle. Mounting systems...- fast 99

UPGRADE BRAKES on a 79 K25
Why? You're poking a sleeping bear. Yes, some folks like to "upgrade" brakes, but the original ones [maintained] are just fine. There are ways to increase stopping power such as different lining material and rear cylinder size. I own a K 20 SB used as a wrecker for over 300k miles. Truck weighs... -
Surface rust. What are the best practices?
Bed is easy slurry blast or sand blast. Slurry blast will not distort metal. To do the same with interior nearly everything will need to be stripped out. Sand will get everywhere. Bed below is a Ranchero just after epoxy primer was applied. Metal is about the same gauge, slurry blasted, no warping -
Rebuild or Swap?
About a year ago needed a 350 rebuilt because GM no longer makes new ones. Afterward had a second thought about the heads. Originals were busted so needed usable cores. That cost and rebuild cost put them near the price of an inexpensive aluminum set with much better performance. What I have...- fast 99
