Got the Wilson remanufactured Delco 27Si alternators installed with new pulleys and fans and belts.

Well then, since you admit that you are biased, I don't believe you should be giving advice to aztrekker, a new member with only 2 posts, who is obviously asking for help. I have never liked manual transmissions, but I don't come on here and bash them. If you can't provide meaningful...

Hold on there Kaiser. Before you go bashing the 700R4, you probably should do a little more research. I have a rebuilt Bowtie 700R4 I'm installing behind my P400 6.5 which is rated for 450 HP and 450 FPT. In its stock form, yes a 700R4 is not as strong as a 4L80E. But the drag racers have...

Guys I have been full circle on this alternator thing, and here's what I have done for alternators for my P400 build - Because I am fully dressing the P400 without taking anything off my running 6.2, I purchased a couple of used OEM alts from a vendor on this site with the intention of...

Dude - this thread is 13 years old. Com’n man.

link?

The factory seat I took out of my M1028 had no latch on the back. Stay thirsty my friend.

GM issued a Dealer Bulletin in 1988 to completely remove that rear proportioning valve. I don't have a copy of the bulletin to attach here, but it is Bulletin 88-320-5 which you should be able to obtain through your local GM dealer. I took mine off and threw it in the dumpster. I also...

Hey Glock - You can't beat an "almost free" 4L80E. You will not be dissappointed. The main reason I went with a 700R4 is because it is a "dumb" unit and does not require any electronics like the 4L80E does. Same reason I decided to continue using the factory mechanical fuel pump instead of...

I installed my first Dana Spicer Trac Loc in a brand new K20 in 1972. I've had many since then. I wouldn't run anything else. The Trac Lok has clutches whiich will slip when turning corners. Remember when turning the "outside" wheel on the front must travel farther than the "inside" wheel to...

I just wanted to post a positive thread about Hillbilly Wizard. I've been getting various parts from John over the past few months and have had excellent results. Recently I purchased a used part from him, and when it came it, it had just a tad bit too much rust pitting for my P400 engine...

You might want to try to crack open the sensor while the system is warm and still under pressure and burp the air out from under the probe. Try this and let us know if that fixes the issue.

Thanks Tow, but I am looking for a source for 2 new 27Si isolated ground units. Cash in hand.

Thanks for all the posts. I opened one of the cases and quickly came to the conclusion that I didn't want to tackle the job. Couldn't figure out how to get the rotor out of the front bearing anyway. So........ I am looking for a source for brand new Delco 27Si isolated ground alternators...

OK I believe I will attempt to rebuild these 2 junk alternators I got from Pennsylvania. Any ideas on how to clean the stator and rotor?

As many of you know I am assembling a new P400 6.5 engine and Bowtie 700R4 transmission for my M1028 rebuild. Every part on the engine is either new or rebuilt and restored to OEM condition. I am not robbing parts off my existing CUCV engine, but instead fitting the new engine with its own...

Now that this thread has come back to life, I will ask the question. I plan to change all my dash bulbs to red LED, so does the GEN2 bulb still need to be different? Also, since LEDs can withstand varying voltage, can the dash light circuit be increased to 24 volt to increase brightness?

Hey I have a stupid question. Are both alternators identical? I understand that the passenger side unit must be isolated ground, and I get that, but can they be interchanged? Are they both 27Si? And one other thing - my passenger side unit has a condenser on the back, but my drivers side...

You are welcome to come down any time. Just let me know.

Update - obtained a used CUCV power steering unit and rebuilt it. Ordered the USA-made Delphi pump from PSE. Popped out the used pump, cleaned everything, and then installed the new pump into the reservoir tank. If you plan to do this, make certain that you clean off all the old paint, rust...
