    Can you ID these transmissions?

    Thanks for the responses guys. The rusty looking (older NV3500) transmission bolted right up to the 5.3! After doing a little more research it seems like this transmission had an external slave cylinder on the passenger side...I wouldn’t think the designers would run a cable clutch all the way...

    Can you ID these transmissions?

    I was looking for an NV3500 to mate up to my 5.3 LS and got a steal on these two shown in the pictures. The guy says he took them out of s10 trucks, one a 4.3L and another was a v8. I did some research on NV3500 transmissions and thought they didn’t come with casting numbers but both of these...

    Stock wire harness to battery and starter

    Thank you very much for the response this is helpful. Sounds like all I have to do is figure out which wire on the harness is from the ignition and figure out the other cable that needs 12v, then run the battery to the starter. My alternator is wired through the stand alone harness on the...

The lighting side of the firewall wiring terminal is straight forward, but the engine side is not so much. To...

    LS Swap Fuel Pump

    Quick question for an amateur mechanic. I have a 74 C10 2wd single side tank and I'm putting in a 5.3 motor. Can I bolt up the EP381 pump in the original tank/sending unit and would that function properly? I'm assuming my tank doesn't have baffles. Or could I run the external walbro 550 pump...

    Opinion on transmission

    Hi everyone I'm in a bind and can't figure out which transmission set up to go for my build and could really use some opinions. All opinions welcome. I'm building a 74 short bed with a 5.3LS stock motor. Intent for the truck will be to cruise to some local shows and maybe drive it one day a...
