I just got myself a 1966 c10 beauty, now I just need to figure out where to start. It came with a 350 small block stick and was thinking of starting with an LS swap or Just upgrading the transmission to a Tremec t56 Manual trans. Then start working from the inside out.
Doesn't have any major rust, just the fender and some surface surface rust. The paints ok for now wish it had some patina, but not so much.
What do you guys think?

I love it, I hardly ever see these trucks around anymore especially now.

Is the 350 in decent shape?

Probably start with brakes and steering first, lots of trucks get upgraded to front disc power brakes and power steering, safety first.

The T56 sounds like a good upgrade since you already have a manual, any idea what rear gears the truck has?

Where are you located?

I am located in California...
I'm not sure what gears this truck has I just picked it up a week ago and got to dig through and see what's going on. The motor seems to run well needs to be clean that's for sure, just the transmission is like a truck transmission. I believe they used to take a camper on it. They added dual gas tanks underneath the fenders on both sides of the back of the truck.
I was interested in switching to disc brakes which set would you recommend?

I used a mixture of OEM parts from a 1974 Chevy truck, used spindles and traded in brake calipers cores for rebuilt from Autozone and used CPP classic performance products out of Anaheim CA for 6 lug disc rotors, and power brake booster master cylinder and proportioning valve kit.

Kept my 1965 upper and lower control arms, rebuilt them with Napa control arm cross shafts, 1974 C10 upper and lower ball joint’s and CPP custom tie rod sleeves to use 1974 C10 factory spindles, new outer tie rod ends for 1974 C10 with new 1965 C10 inner tie rod ends.

I bought the 1974 C10 pickup for cheap, also took 454 and TH400 from it, the 454 ended up being decoded to a 1968 C10 396 big block, also used power steering pump and steering box.

This was bought in early 2003, the square body trucks were cheap and easy to find then, 2022 not so much.

It wasn’t until 2011 I got it all completed, work, etc got in the way.

I’m not sure what the choices are now, maybe you can buy new aftermarket spindles that go on your 1966 upper and lower ball joints, then 6 lug rotors and caliper’s, power booster master and proportioning valve combo, new brake hoses etc.

Someone else may have options that are available for 2022.

I saw a few different option on Holley, I have to take a look to find the difference.

Unless anyone has a recommendation on disk break conversation?

I shined the bad boy up this weekend.

I just helped my neighbor get a '65 C10 running with disc brakes from CPP and a LS conversion. I sold him the truck a few years ago since I had too many projects, along with the LS engine and tranny. He put a 4.8L out of a '04 truck with a 4L60E transmission. If you're interested in how he did it, I can give you lots of specifics.
His brakes came from CPP, and he used a drop kit that allowed disc brakes in the front to lower the truck 2" front / 5" rear (I think). I'd prefer stock height, but that's a personal preference. His truck looks good now.
The CPP guys were very good to work with and everything fit as expected.
He looked at doing a manual transmission in the truck, but the 4L60E was considerably cheaper and easier with a LS motor. Mostly, it's hard to find a LS truck motor with a manual transmission.
As for other transmission options, I did put a NV3500 out of a '98 chevy truck in a '65 C10, and that fit. The modifications I had to do were: electric speedo conversion, hydraulic clutch conversion, and I had to remove the crossmember that holds up the bellhousing on the SM420.
You can put a tranny from an older small block on a LS engine, but it requires a special flywheel.
Problem is, by the time you add up the costs, you'll be spending a minimum of $400 on the flywheel and clutch, and you can get a good used 4L60E for not much more than that.

Ill check out CPP for my disk brake conversion.

What T-56 manual transmission do you recommended for my C10 66. I was think junk yard buy, but not sure which 1 to purchase.
There $4000 new online.

The new T56 magnum are expensive about $3295.00 plus bell housing is almost a grand, then you have to figure out how to make your clutch pedal hydraulic several ideas ways to do it, some are expensive.

There is a new 5 speed called TKX made by Tremec the same company, it’s $2795.00 but may cost less in the end vs T56 magnum, it’s very strong and has 5th gear as overdrive.

Maybe a T56 from 1993 Camaro/Trans Am with the LT1 engine to bolt up to the 350 you have.

Or maybe you could buy a complete 1998-2002 Camaro/Trans Am with T56 and LS1 engine, hopefully it’s not a really nice car as the price would be high.

The later Camaro with LS3 and T56 would be even better.

How much power are you planning on making?

Just at pull n save and there was a 1991 Camaro with TPI engine and T5 transmission in car, I read they only were used with 305 engine and 350 cars got automatic.

If you are just cruising the truck maybe a T5 could make your highway mpg much better.

It’s $175.00 for a transmission there, I just pulled a 700R4 from 1991 GMC pickup Saturday to swap into my 1965 C10, going to have it rebuilt first.

I think the T5 had .63 5th gear ratio which is more overdrive than 700R4 .70 came with, so more mpg cruising depending on what rear gear ratio your truck has.

I would love to get around 400-500hp ish when completed. I'll take a look at the TKX transmission seems more reasonable. Thanks for the reply!

Unfortunately, you appear to have a 305 someone told you was a 350. That's the "5.0" in the casting at the top driver rear of the block.

That's what I figured... Just my luck. How can I find out what year this engine is from? I need to know so I can buy a new transmission for it.

If you flip that picture 180° so the 5.0 is right-side-up, look to the left in that same general area of the top/rear of the block, you should see a longer string of numbers in the next section - 8 digits to be exact, and likely beginning with 140 or 141. Then look it up on https://www.enginelabs.com/news/reference-chevy- en...

Towards the driver side, that's what I meant by look at the section to the left of where you see the 5.0

"How can I find out what year this engine is from? I need to know so I can buy a new transmission for it."

I may be mistaken, but I think you know everything about your current engine you need to know in order to buy a transmission for it. While there are 305's that are 1 piece rear mains and 2 piece rear mains, that won't affect which transmission to buy. You do have to use a matching clutch and pilot bearing, but that's just a matter of selecting the right parts.
All 305's are Gen 1 small blocks and while there are different bellhousings that can be used, any transmission that fits a one piece rear main will fit the two piece.
Looks like you currently have the SM-420 4 speed that was common in those trucks. It has a bell housing that includes rear motor mounts, instead of a typical rear mount on the transmission. In order to use any of the transmissions you're considering, you'll need a different bellhousing and rear crossmember. The automatic crossmembers will work (but they're rare), or there's aftermarket options. In some cases, the bar that holds the rear motor mounts will interfere with the new bell housing and will have to be removed.
If you do buy a transmission for the 305 you have, if you later switch to an LS variant you will need a different bellhousing for it or adapters.
That said, you've posted before that you want to make 400-500hp. I don't think it's practical to make that much power from a 305, so I would hold off on buying a transmission until you're certain what engine you're going to use. While it may be possible, it's probably cheaper to source another engine to make that much power. Most likely, you'll be able to buy an adapter or different bellhousing to make it work, but that's a lot of cost that you'll be throwing away.

Thanks for the awesome info.
I was sure if I had 1 piece rear mains or a 2 piece rear. When I was looking at transmission it would ask...
I though I had a 350 until I uncover it was a 305.
I was thinking of purchase a 5.3L LM7 engine in the future until the 350 died, but it only a 305... Now I think I'm going to wait until I get a LM7 or similar engine until I buy my transmission.

1 more question how to I know if I have a big hump or low hump for the transmission?

This the way I went too, used stuff from early to mid 80’s for all this. Order REZ kit to mount power steering box.

Search my name lots of posts but pics are gone.

Hello 1965C10 good to see your still on here. Still terrozing the neighborhood in my ‘65. :evil :

So I'm going to start with just getting solid brakes. Looking at keeping my drum brakes at the moment till I have money to get disk.My truck currently has power brakes,but a single master cylinder. What dual master cylinder would you recommend since I already have a power brake boaster or do I need to replace that as well?

Thanks for the feedback

How’s it going Fritz?

Looks like 1971 was last year of front drum brakes on C10, so maybe a 1967-1971 C10 dual master cylinder would work, as long as the pushrod on the power booster is the correct length.
