1966 C10 Auto to Standard Transmission +Engine Swap
Hey Members,
I am hoping to get some wisdom about my plans for a 1966 C10 that I hope to make a dependable daily driver. Currently it has a bad 700r4 transmission and a 4.3 V6 that was taken out of who knows what (I should take photos of the homemade motor mounts it is setting in. WTF is all I can say about that). My wife says that I can spend 10K max to make it a dependable daily driver. So my thoughts are to buy a turnkey crate motor (about 5K from blueprint, jasper, or someone else w/ warranty) and a standard transmission (hopefully 2K or less with clutch and bell housing). I am not sure which engine/transmission would make for an easy instal that I can accomplish over the Thanksgiving Break. I am sure that I will also need foot pedal assembly for clutch pedal. Has anyone done an auto to standard transmission swap like this? If so what were the troubles you ran into, and what advice would you give? Thanks in advanced for any help!!! Mark P.S. I saw Jocko has a nice post on swapping to a T-5 but it sounded like that was manual to manual transmission swap. Last edited by 0bad0boy7; 10-23-2017 at 08:47 PM. |

Re: 1966 C10 Auto to Standard Transmission +Engine Swap
Was your truck originally a manual or auto? Summit usually has some good prices on their crate motors. May want to take a look at them. Also a supporting membership will allow you to post want to buy for the little things that you are going to need. Motor mounts, pedal assembly etc. Also pics would be helpful to what you are starting off with.

Re: 1966 C10 Auto to Standard Transmission +Engine Swap
Powers & PGSigns: Thanks for the reply! I am not sure what the truck was originally since the steering column, engine, and transmission are all transplants.
The motor is a 4.3L V6, which I understand to be similar to the 350 V8 but missing the last two cylinders. |

Re: 1966 C10 Auto to Standard Transmission +Engine Swap
Is the v6 a vortec? If so I could consider keeping it if you just want a daily driver. I don't know if you would be able to shred the tires like you could with a sbc, but the 4.3 vortec v6 was a good motor. A friend of mine had one in his truck, and he kept up just fine with the boys with 454s.

Re: 1966 C10 Auto to Standard Transmission +Engine Swap
I went from a TH400 to an NV4500 in mine. Hydro clutch master from Willwood, slave from Dorman. Not apples to apples but kinda. Had to get the pedal assembly which went in fairly easy. Clutch rod to master alignment still bugs me but I drive it all the time nonetheless. Using the factory V8 motor mounts for the big block. Wish I could have moved it forward an inch. Stars have to be aligned, tarot card in order and my wife shaking animal bones in a jar just right for the passenger side valve cover to come off

Re: 1966 C10 Auto to Standard Transmission +Engine Swap
Lil Loafer & 63GENIII: I think it is a vortec 4.3... The motor is crammed so far back into the transmission tunnel that I can not see the casting number on the block or heads. I am going to pull the engine/transmission out this weekend and see what those numbers are. I could save money big time if I could have this block/heads rebuild. Then I would only need to find a good standard 5 speed gear box, bell housing, clutch, foot pedal assembly.
Can you move your engine/transmission forward by moving the mounts and a longer drive shaft? I don't know how many problems I have gotten in thinking that "It should be easy as that" and then realized half way in " I didn't think of X, Y, and Z." |

Re: 1966 C10 Auto to Standard Transmission +Engine Swap
Nice truck. Don't forget to budget in time and money for wiring. If you are looking for a reliable driver you don't want a spliced/hacked mess. The good news is quality harnesses are available for both stock and custom applications, but I was very surprised how fast the cost added up.
Good luck, Tom

Re: 1966 C10 Auto to Standard Transmission +Engine Swap
If I remember correctly... the 4.3 Vortecs will have the word Vortec on the valve covers. Do I see A/C there too? Seems to be a nice little pickup there.

Joseph, the truck you drew at the bottom of your signature page is awesome!

Re: 1966 C10 Auto to Standard Transmission +Engine Swap
Ya know, the 4.3 is still put in base trucks today but they have fuel injection and have nice power. Just a thought.

Re: 1966 C10 Auto to Standard Transmission +Engine Swap
When I swapped from auto to stick, I found a rusty, crusty parts truck that had all the manual tranny stuff intact. That way I had all I needed plus a few good "other" parts. I even sold off some of it when I got done.

Re: 1966 C10 Auto to Standard Transmission +Engine Swap
Was the donor parts truck a 60-66, or did you have another year and model that worked for you?

I don't do them all the time. I am a school teacher (second grade for now, but hopefully soon wood shop and welding). It is looking more and more like I should have the 700R4 transmission rebuilt and put some real motor mounts under the 4.3L engine. Focus on the suspension and breaks next, rebuild the motor last, and cosmetic stuff very last. P.S. What happened? What did you domino with? |

Re: 1966 C10 Auto to Standard Transmission +Engine Swap
If you do end up having the 700R4 rebuilt, make sure that the TV cable is connected correctly and that the trans pressures are correct. If you do not, that new trans will not last long.

X2. Unless it needs a motor I'd leave it, spend the money on other things.
