Electrical dash wiring / wire color issues.
UPDATE: Found this photo, with a much better detail on the pin out for the 1227747 ECM in the 1987/1988 RV: It shows the Orange with Black stripe as the 700R4 Neutral Safety ECM wire. This picture above is completely different the the 1987 Typical wiring harness diagrams. This diagram below...- RanchWelder

Electrical dash wiring / wire color issues.
I'm rewiring a custom dash in my 1987 Blazer. I'm used to just using my Amprobe with a pair of wire spikes and verifying these things as I need to. Without power with so much of the dash opened and with thin gauge dash light kit in a custom aluminum entire dash console and dash board, I'm in...- RanchWelder

Auto A/C vacuum pump. lots of CFM or Less CFM whats best?? A/C tech's please help.
I'm not perfect or feel the need to to be correct all the time. I'm learning constantly. Please teach me how what I wrote could be improper? Not a physicist... not an engineer... just a human that cannot stand planned obsolescence. Please test the cheap $89 ebait pump with a quality Winters or...- RanchWelder

Auto A/C vacuum pump. lots of CFM or Less CFM whats best?? A/C tech's please help.
RSMII, Your 1980's pump is probably not the one from Ebait for $89 made in China, is it? At 5000 ft, the transmission test manual states the vacuum potential will be less due to elevation, "AT THE RATED HP OF THE ELECTRIC MOTOR". ...and it is. Now imagine the Chinese gentleman who rated the...- RanchWelder

Auto A/C vacuum pump. lots of CFM or Less CFM whats best?? A/C tech's please help.
Verify the pump works ASAP, is my best advice. This is not really a professional unit like you would find at Grainger. Few A/C charges a year and some bench time for a transmission rebuild for Valve Body testing, like shows in his videos, is why I opted for this version. If you are serious...- RanchWelder

Elevation makes a difference. Former A/C tech. Repaired microwaves. Studied Multi-Channel microwave coms too. 512 Universe DMX programming systems for moving lights. Personally wired 8-12 Universe lighting systems for corp symposiums. IBM 14 years. 5 cfm pump will not pull 25 HG at 5000 ft...- RanchWelder

Are OE lug studs long enough? 77 C10
Aviation AP Mechanical standard is at least 1 full thread protruding from ANY and ALL fasteners, (with proper washers, as required). Zero deviation. Anything less is 100% failure, gross negligence on the mechanic. Some GM lugs that use a plastic cap are intentionally over-sized so they do NOT...- RanchWelder

Should my TBI's fuel pressure act like this?
o-rings everywhere. Don't forget the OEM fuel filler hose and vent hose are probably dry rotten and leaking from rock hard rubber in the filler lines.- RanchWelder

4x4 with 31x10.5/15 tire. Anyone running this size tire on stock lift??
I see this thread is a few months old. Pardon me if you got the info you were looking for earlier... 265/75 R15 will work and can be found in 10 ply, if you search hard, with good quality road treads. Just bought 2 of these and they were affordable and looked very good quality, so far. Could...- RanchWelder

Lift or rebuild stock?
So this is a tough solution... Be very careful what you do with this advice, OK? Not my fault if you screw yourself up... You are warned... https://www.amazon.com/dp/B06Y1B82TG/ You can mix this stuff 3:1 water to acid and clean the crap out out your springs frame and shock mounts. 50/50 is...- RanchWelder

Lift or rebuild stock?
Just went through the same conundrum with my build. It's worth investigating what you have now, vs "actual off the showroom floor stock height". After installing 8 inch longer 3/4 ton leaf springs on shackle flip perches, the measurement at the center of hub from the ground to the fender is...- RanchWelder

Well, I'm seeing the sensibility in mounting it on a riser and keeping the parts that need to move clean by raising the shifetr and keeping it inside the cab, instead of hanging down in the dirt.

Three or four from leafs
The aftermarket springs vary in thickness. If you go to ORD and search the aftermarket import springs vs their custom springs, you'll see the ride and the height differ because custom quality springs are thinner and ride way better than any stock or aftermarket spring. $$$ Check out Jay Leno's...- RanchWelder
