Yep! Everything I'm doing is stuff he taught me to do. I know that this project will be our last together and I'm really trying to savor it. He's still my hero and Alzheimers sucks.I see your dad in the support role. Good stuff.![]()
Good on you. You just never know when something will inspire him to tell you a story that you never heard before, and you’ll go ‘Wow, that was cool.’Yep!

I did the same back in 2021 with an H7 AGM battery in my '79.Huntsville, TX is getting a cold snap this week, so this morning between the cold, the choke, and the 4 year old Toyota TrueStart battery, I was dead in the water. Had to take the truck to work. But, as I am wont to do, the work computer instantly became a research vessel for my options to replace the battery. What I quickly discovered is that group 27/27R/27F AGM batteries are not available locally, and are expensive. My current Toyota TrueStart 27F battery has the poles reversed, which I like because on a '78 it keeps the negative cable away from my washer bottle. After much reading, I had to leave work, but here is what I jotted down on a sticky note:
Group 27
12.0625 L
6.8125 W
8.875 H
Group H7
12.4 L
6.9 W
7.5 H
Group 65
12.1 L
7.2 W
7.6 H

So, observation of the battery hold down, the tray, and everything below it, has revealed to me that lead acid batteries "outgas" or leak, whatever, like crazy and eat up your metal stuff. My 74403-60050, aka the "12 inch battery tray" after 4 years looks like crud! So the goal now is to switch to an AGM Battery... but not spend a ton of money. Quick anecdote on AGM and why you want it: my 4 wheeler has a "PowerSport" battery, the ones you add the acid to after you buy it. Those things have always been good for maybe a year, and then you have to start putting the charger on them, and then within 8 months you are replacing them again. I put an AGM battery in there and now it cranks every time. I mean it is actually weird to me, to walk down to the shed and the wheel turns over, even if it has been sitting for 6 months. So now the diesel truck has 2 AGM batteries, and it is about time the 40 joined the club. So, the TrueStart came out, and let's clean stuff up. I made a baking soda solution to soak stuff in and measured the tray as thus:
12.25 L
7.0 W
7.5-8.5 H

That's Fluid Film all in the bottom of the tray, it did not look so yellow in person. So, after everything was cleaned up, I test fit the battery... Note that 12.4 length, yeah that was kind of a problem. It was SO CLOSE. BUT, new batteries have this big lip around the bottom, because modern cars use that lip to lock the battery into the tray with a rubber block. So, for the 40, that lip can be CAREFULLY trimmed.

Watch the center of your cutoff wheel and DO NOT get it into the body of the battery like I did. But it survived, thankfully. Just be careful, this is so close it does not take much, in fact I tried using a manual file first, but it takes a little more than that.

The file was handy to cleanup afterwards. After this, I just made sure the tray and hold-down were clean and covered in Fluid Film, and then I installed the new battery. Oh, I kinda forgot the whole point: the H7 EverStart AGM battery is less than $200. And I have had good luck with this brand, they are all made by the same people.

Things I like:
AGM
Price
My military battery terminals fit perfect into the sunken recess design.
After a bit of surgery, this is probably the biggest battery you are going to fit in that tray.
850 CCA.
Another option.
Things I don't like:
Having to cut on a new battery.
The battery is shorter meaning the hold down nuts have to be threaded WAY down.
The hold down angled corners do not touch due to the battery design, so the middle is all that is holding it.
Not Toyota (come on!).
So there you have it, I read many excellent write ups here on our forum about some of these options, but no one had touched the H7 yet, so thought I would share. The 65 might be a good one as well, but I wish the 27R AGM was more available and less expensive. Hope it helps someone. Have a great day!
3hrs? (also depends on what’s included in the “tune-up”)Anyone able to provide an estimated time for labor that a shop would take to replace the exhaust manifold gasket, swap out the carb and do a tuneup? Shop charges $150 an hour......
3hrs? (also depends on what’s included in the “tune-up”)
would add another hour (or so) to properly set the valvesThey said 16 hours….lol. I was thinking 3 hours should be enough time. Swap out the manifold gasket, swap out the carb and dial it in, set timing/valves. I’m sure I am minimizing the amount of work that goes into it, but 16 hours sounds crazy.
If you are still smogged, 3 hrs is insanely low to do that. So 1 hr for manifolds. 1 hr for carb remove and reinstall, tuning, 1 hr for plugs, wires and valve lash….They said 16 hours….lol.

Might be a good idea to have the manifolds machined and spot faced.Mine is a 1F engine…no smog stuff. I’ve already done the plugs and wires.
Good point.15 hrs is we don't want to do the job price. 5 is the we only want to screw you a little price.
