Why do you love your TH350?

[nickdaddydollar]

Thank you in advance for any input you may have.
I just bought a 79 k10 franken-truck, (not the original motor, transmission, rearend) and am beginning to find out more and more about my truck. I know that my truck has a 350, with a 4bbl edelbrock carb, and has a TH 350 transmission. My question is:
I am not quite sure what this transmission is capable of, and what it's best attributes are. Im a little concerned, because with my current setup, I am unable to cut the tires loose and spin out?
I know on the surface, my criteria may seem a bit childish, but I previously owned an 87 Scottsdale C10 with a 350, and couldn't keep those tires from spinning out.
My current truck appears to be, and sounds like, it's running strong, and efficiently. I have replaced all the plugs, wires, distributor cap, and rotor.
Is my expectation, of being able to spin the tires on this beautiful 350 sbc, with this transmission, to high?
Let the education begin...now!

Id say more like the rear end gearing

It's not the transmission. They are plenty strong enough. I had one in this.

You went from a C10 to K10. It's heavier and being a '79 probably only has 3.08's in it for gears (or close to it). Not to mention it's also probably an np203 which is full time 4wd. Just need to free up the drivetrain a bit. Could also be the tire compound. I had a Duramax with a 120hp tune and could blaze the tires until I put a set of Dick Cepeks on it. They just stuck to the ground.

Were you ever in the 4wd jamboree nationals in bloomsburg pa? That truck looks really familiar!

No, I've always wanted to go but never made it. That was at the New England Summer Nationals.

I swear ive seen that truck

 

[TubeTruck]

I swear ive seen that truck

I had it between '98 and '03 but I don't believe I ever left New England with it. Maybe you saw it in pics somewhere.

 

[78C10BigTen]

Possible. Maybe not since 03 i was still in high school in northern pa lol maybe my minds playin tricks on me

I try to not spin my tires, hard on tires...

My old dog is too lazy to spin them unless its rainin and i do it with the wheel completely to one side lol

When you get 4 bald 35" tires for $10 at a swap meet its hard not to use them for burnouts lol

np203? What is this?

The transfer case

Spinnin aint winnin!

You probably have taller tires on your 4 wheel drive too.

I'm assuming your old truck had a 700R4? 700's have a really deep 1st gear compared to th350s or th400s. Which will put more torque down and make it easier to spin them.

But in terms of strength of a th350, they are plenty strong for most small blocks in stock form. Modified they will handle a hot small or big block no issue.
David Freiburger runs a gearstar th350 in the Crusher Camaro, a car that runs in the 10's and will pull the front tire off the ground.

If you have a 203 that hasn't had a part time kit and manual front hubs installed, it is a full time transfer case, which will make it more difficult to spin tires due to drag/parasidic losses.

As mentioned above, if you spinning, you ain't winning.
