Finally got the torque converter installed. Plan was to do this once the cab was back off, but changed my mind. Had to yell for help as I was pulling it! Glad I had it strapped on the jack or I would have had an expensive night. As I was moving the jack back the handle came out! I was in a tight spot. :lol: Transmission is going back in tomorrow. Down to the radiator and we can turn the key!

Re: 1971 Stepside LS Build
What's the scoop on the torque converter bolts? I planned to use the ones that came with the Circle D converter but read somewhere that they're too long for the 4L80e flywheel?? Is that why you have the ARP bolts?
Might use your Amazon/Spectre MAF sensor setup, it's very simplistic. Keep up the good work, can't wait to hear this thing purr. |

Torque Converter installed with no issue. Ended up having to use one shim to be within tolerance.
I installed the O2 sensors that came with my engine and discovered they didn't work with my harness. I found out the Denali O2's are different than the standard truck O2 sensors. So, ran to the parts store and picked up two new ones and installed them. Finally, poured in some oil and turned the key on the see if I could get the fuel pump to prime the lines to check for leaks. Special thanks to Custom68 for helping me figure out I had a grounding problem. Once that was solved it all came to life with no fuel leaks. Hopefully we can start her up next week. |
Re: 1971 Stepside LS Build
Exciting! I had to use the smaller of the two shims on mine as well. Your truck is coming together nicely.

Nice progress. What trans cooler are you running? Remote heat sink on the frame?

Re: 1971 Stepside LS Build
I am glad you got the grounding figured out. I am also glad there were no leaks. It is coming along very nicely. Once you get the radiator don't forget to add about a gallon thru the upper radiator hose into the engine block. If not it will air lock and not pump the coolant.
It will be exciting to hear it for the first time. If it doesn't fire right up holler again my injectors seemed to have gotten gummy from sitting the first time I fired mine up. good luck and keep the pictures coming. Dave |

Installed the oil cooler over the weekend and took her off the jack stands. Overall I like the stance of the 4/6 drop now that it has the weight of the engine and transmission on it.
I fought and fought the new inner fender on the passenger side. Several of the holes don't line up. Has anyone else had this issue with the Goodmark fenders? I am about to take it completely off and start all over. For the life of me I don't know how I will ever get these inner fenders in without scratching them all up once painted. Radiator has shipped and will be here Wednesday. Was hoping to roll her out on Saturday and fire her up, but winter returns this weekend. |
Re: 1971 Stepside LS Build
Looks good! What's the details on the oil cooler? Did you connect it directly to oil filter housing with adapter to A/N fitting? Got more pics of that?

Sorry, I don't have a specific pic of the lines coming out of the transmission. If you look up at post #82 you can see one of the fittings there. |
Re: 1971 Stepside LS Build
My bad, for some reason I thought you were talking about engine oil cooler. Too many threads I'm following I got mixed up. This forum is awesome with knowledge :metal:

Re: 1971 Stepside LS Build
What are your plans for the brakes? I have the same Astro van setup as you. I have stock rear drums and am doing a front disc conversion and I'm planning on using the Astro master cylinder and a residual pressure valve for the drums, but not sure about what to do about a prop valve yet.
I've been talking with GMC Pauls and they have a brake line kit which might match up with the Astro prop valve. The kit has a single 3/16" line to the prop valve for the front drums and a single 1/4" line to the prop valve for the drums. I was going to buy a disc/drum prop valve from Speedway Motors, but it has (2) outlets for the front so now I'm thinking about using the Astro prop valve. |

It is so nice here today that I wanted to skip work this afternoon and push her outside for some sun, but I didn't. Here is a shot of the the stance with no bed or hood and a few other key parts :lol: |

Here are the part #'s: -GMC Pauls complete line kit (does not include tees or unions, but does include the lines out of the prop valve, front lines, front to rear line, and rear axle lines) - 1801002. These are OEM steel. We used stainless on my dad's truck but found out that it's incredibly hard to work with since it's so hard which makes any modifications difficult because it takes a special flaring tool and you have to tighten the fittings, loosen, tighten again, tighten some more, etc. to get them to seal. -10 psi residual pressure valve - Speedway Motors - Wilwood 260-13707/Speedway 83526013707. I plan to install this somewhere in the middle of the front to rear line. Cut the line, slide the nuts over each end, flare each end, then thread into adapters that thread into the residual valve. -Inverted flare nuts for 1/4" line - Speedway Motors - 91031819 - 1 bag. Put these on the ends of the cut in the front to rear line. -Inverted flare to NPT adapter - Speedway Motors - 91031828 - 2 EA. These adapt the inverted flare threads on the lines to the NPT threads on the residual valve. |
Re: 1971 Stepside LS Build
MDPotter...you are the man! Thank you for this. Helps out a lot.
The parts you listed will give me lines front to back? |
Re: 1971 Stepside LS Build
I hope it works! I've had plenty of time to research all of this as we finish up my dad's truck. But I'll be tearing into mine in the next couple months. So if you get your brakes working before mine, let me know how it goes!
