Some silly Q's
« on: January 18, 2010, 09:51:49 pm »
Does anybody know why GM never had the 400 engine in the 2wd C-10's? Secondly, this has been bothering me for a while, and I don't want to sound dumb, but if you have a manual valve body on your trans, does it act like a manual if you take off in third? Like 3rd gear stick = 3rd gear turbo 350.

Yes, if you stick your trans in third, it should take off in third(if you have a manual valvebody).  I asked about that when I was doing research on the proper way to do a burnout with a RMVB.  They said start in 2nd.  Also, I'd heard of guys with a TH400 taking off in 2nd...I'm think to kill some of the gear ratio or something like that.

Would that superheat the T/C; kinda like smoking the clutch?

I'd guess if anyone were to steal your truck, it'd be a dog starting in 3rd ::)

400's were only optional on the K10/20 in 1975, the next year they was the last.  No idea on why.

Hmm. Maybe that motor that guy sold me didn't come out of a 77 K30. I did check to make sure it was a 400 though.

I don't want to sound dumb, but if you have a manual valve body on your trans, does it act like a manual if you take off in third? Like 3rd gear stick = 3rd gear turbo 350.

  I've got a Turbo 350 manual valve body from Fairbanks transmission in my 69 camaro.
  I've tried what your asking and this is how mine works.
  If from a stand still you place the shifter in 3rd and start moving my tranny is still in 1st gear. Now your in the odd position of driving with the shifter in 3rd but the trannys in first, so now to shift to second you have to pull the shifter back down into 1st that back up into second.
  Maybe not all manual valve bodys are the same but in my car no matter where you place the shifter it will always start off in first gear. Theres no way you can start my car in 2nd or 3rd gear.

I had a customer with a C10 with a 400 in it he swore was factory (76 I think) but he coulda been full of it. My 80 C10 had a 400 but that was a replacement from the 350 Diesel.

I went here- http://brochures.slosh.com/ from the post Weird Option Code and rigged up my truck. Then I looked at motor options and all they (GM) had was 400's in the K series. I just thought it was odd it was a 4 wheeler only deal.

Fitz- I read on the internet that it's bad for the tranny if you downshift? Like 3rd at 55mph it's bad to drop into 2nd. Like you have to come to a complete stop and then put her in 1st. That true?

I have a 77 LWB C10 with the F44 if anyone was to look it up in the last pic.

Maybe it was 77 for the last year now that I think about it, I will have to check.  I don't think it was ever offered in 2WD  though.

Well from 81-86 you could only get a 350 in 4x4, 4x2's could only get a 305.
