Did 86 silverado come with 305 and 700R4?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

NASTY-LSX · 07-07-2015, 05:14 PM

I thought they came with 5.7 and 3 speed automatic's. Am i wrong? thanks.

TwoFiftyShifter · 07-07-2015, 05:17 PM

A C10 in 86 would have come with a 305. I am not sure if 350 cubes were available in half ton at that point. 700R4 was available but I'm not sure if a TH350 was (3 spd auto)

GRADYS Performance · 07-07-2015, 05:40 PM

The TH350 ended production in 1979. The 1980-1986 transmission was a TH350C which had a lock up torque converter.

Was a 700R an option?? I have a guy wanting to trade me a really nice 86 silverado. He says it all factory stock, he said it had a 700R4 overdrive trans.
I thought the 700 came out in 87 for the squares..??

The 700r4 was available as early as 82, as we bought a new c10 with a 6.2/700r4 even with the weak 6.2, the early 700s were weak, or at least the one we had was.

My 86 Silverado has just that package. 305/700R4. I thought it has a V6 when I took it for a test drive before I bought it because of the lack of power.

natedogg · 07-07-2015, 07:03 PM

I'm not 100%, but I think a 350 wasn't available in a 81-86 C10. Only 6 cylinders and 305 V8. Some 82-87 C10's had 700r4 and some THM350c.

44th Miss Inf · 07-07-2015, 07:13 PM

I believe the 350 was dropped from the half tons in the square body except some of early California models. I don't think ESC passed pollution standards there.

Mine was a 305/700r4 and it had just as much power and spunk as it does now with a 350.

xole · 07-07-2015, 11:24 PM

If I am reading the docs correctly from the GM Heritage center for the 1/2 ton there was a single 350 (LS9) option mated with a 700R4 (MX0) for California only. Only 2.73 and 3.08 gears were available with that option.

305 (LE9) was available with 700R4 (MX0) Non-Cali with either 2.73, 3.08 or 3.42 axle ratio. This was also available in Cali but lost the 3.42 gear option.

andrewmp6 · 07-08-2015, 02:35 AM

1982 the 700r4 came in the 1/2 ton and 3/4 ton trucks 2wd and 4x4.The turbo 350 was used 73-81 1/2 ton and some 3/4 ton.The 305 was used 81-87.

85/Silverado · 07-08-2015, 12:01 PM

My 1985 Silverado came stock with a 305 and the TH350 tranny. Bought in Ga.

The stock transmission in a 1985 Siverado if it was a 3 speed automatic would have been a TH350C not a TH350. The TH350 was not produced after 1979. The TH350C has a lockup torque converter and the transmission and converter are not interchangable between the two.

BamaDave · 07-08-2015, 01:28 PM

simple answere is, Silverado's were only available with a 305 (5.0), the 700r4 was a upgrade option to the th350

RED1985 · 07-08-2015, 05:34 PM

Same here - 1985 with a 305/700r4

Liberty · 07-09-2015, 10:22 AM

Can Confirm - 1982 305/TH350C

Later Swapped for a 350 Crate.

The 350 was installed in all California bound trucks however if they were normally meant to have a 305.

Malo83 · 07-09-2015, 03:26 PM

My 83 Silverado has the 305/700R4 factory setup, for being a boat anchor the little 305 still runs great

1970pelle · 07-10-2015, 09:21 AM

My 86 before the one now was a C10 short box. 305,4bbl, 700r4 and it did run good. Better after a few small upgrades. I miss it.

C.W · 07-10-2015, 03:11 PM

I also have an 86 short box that was originally a 305, 700r4, 3.42, G80 (gov-bomb) combo. Heavy duty springs, so it rides like a rock lol. Barebones otherwise....

I don't know about the 350/5.7, but according to my VIN, MY 86 C10 Silverado left the factory with a 6.2 liter diesel...

AntiGov · 08-17-2019, 12:01 AM

My 85 k5 silverado i bought in 87 had the 305 / 700r4 combo . The 700 was junk in those yrs and it only lasted about 70k miles. The q78 buckshots didnt help though

100%Chevy · 08-17-2019, 09:52 AM

I bought my 82,K-10 new.It came with a 305/700-r-4 trans.
I could not buy one with a 350 engine.
Was told I had to buy a C/K-20 truck to get it.

Leonard60 · 08-17-2019, 08:42 PM

My 86 Chevy had a 700r and a 350 cid engine. I’ve been told that 350 cid was available in Canada. My 89 Gmc also had a 350 cid and 700 trans.

I'm never one of those guys to blather on old, resurrected threads about how old it is if it's relevant. However, on this one, I think the original poster got his question answered about 4 years ago. But y'all are welcome to keep adding to the info in the thread.

87 came back with fuel injected 350 in half tons
