Another concern inside the frame rail is heat transfer to the cab floor. The most common way I have seen is people make a flattened down pipe and do at least 1 inch cab lift. Otherwise, outside the frame is your only real option.

The gist of the long thread yesterday is that I don’t know exactly what my timing is because I don’t know the timing probe offset. Yet, I now have an accurate timing reading that is repeatable and I advanced the timing a bit. I wrote that and went for a 231 mile drive into the hill country for...

Todays Topic is injection pump timing. I have owned a 6.2 or 6.5 for almost 11 years now. I have replaced at least 6 injection pumps on varies engines in the same time span. I have also been looking for an accurate way to set the IP timing after pump replacement or to just baseline a running...

That is a tough one. Figure $3k for a new system. Figure $500 - $800 plus exhaust for a GM turbo system. Somewhere in between is your price. I haven’t looked lately, but $1200 seemed to be the eBay price a few years ago. That was without exhaust though. But exhaust will make shipping very...

You are in experimental land with this one. Keep in mind that no power is actually pulled from the front battery. The 12 volts positive for most of the truck systems is actually pulled from the negative side of the rear battery. Kind of confusing to think about and even tougher to...

There is a diamond shaped black plastic 2 post wiring connector above the driver side cylinder head on the firewall. Give the wires going to it a tug and see what happens. Same with the Buss bar connectors on the passenger side firewall. 1 loose or corroded connection can cause this problem...

Where is the high beam indicator? I will look at my 1952 REO and see if it has the larger light pods or not. I don't think it did.

The gauges are of a different manufacturer than the later multi fuel trucks too. I think Stewart Warner. Here is the only picture I have of mine here at work. 1953 REO.

Was the heater on high, lights on and wipers flapping? Even then it shouldn't drain the battery that fast. Check your batteries and have them load tested. Then go from there. You might have a bad alternator, but something else is going on as well.

LMC does have a listing for the tail gate seal under Blazer if you look at the page titled for removable top models. #11 on that page. However, the best way to get the right part is to look in the TM ending with -20P or -34P. That gives you the exact GM part number for what you want. Then...

Exactly, that is why I tried to nicely suggest a new drop in drive train might be a more cost effective solution.

12.6 volts is what the battery should be at with the truck off. If you don't have that, you need to charge the battery before you do anything else. You should also load test the battery. How long are you cranking the engine to get it to start? Something is pulling voltage from your battery...

That looks like fun. You might get a better deal and better results from buying a complete center mount turbo engine/transmission assembly. There always seems to be a unit for sale either on this site or other online auction sites. Getting a complete engine assembly that is known to be good...

I was able to reserve spot #8 on my work computer just now. I wasn't able to do it on my ipad from home yesterday. I'm taking the M715 camping this weekend with my Trail Life troop. The March camp out every year is the learn to drive a manual transmission event for the young guys. The M715...

I have the Compushift controller. It doesn't need a tach input to work but it does need one to show rpm on its display. I also have a Dakota Digital gauge cluster which does need a tach input. So, I have the TCM and the gauge cluster both getting the signal from the Dakota Digital converter...

Thanks for setting this up. I hope to make it Friday evening with the Cowdog.

I have a 4L80E in a 1987 Suburban that looks like a CUCV. I can’t think of anything different between them concerning 4L80E installation.

I forgot about the oil pump drive way. I had one of those and tried it first. It leaked oil out of the plug housing when I test ran the engine. Then my serpentine belt drive vacuum pump froze up soon after. I went with a CUCV vacuum pump and promptly forgot all about the speed sensor back...

It is certainly evident who has made a 4L80E work in a truck it wasn't meant to and all we learned making it work. Neat to read about different ways to do the same thing too.

I was typing while you asked your question about the stock CUCV tach signal. It was for the STE/ICE diagnostic suit case they used back when the trucks were new. Think all analog OBDII with no real information from a 4 digit digital read out. I went to the trouble to find one that worked and...
