1994 Silverado 4.3 V6 to LSX swap complete

[1991SSP]

So far so good with my swap, I have about 800 miles on it and I have to contribute alot of it to the help from those on this site, just thought I'd post some pics of my swap, truck started life as a base package 4.3 V6, it had been in a hail storm sometime back and still has the dents from it, for now it's a nice hot rod to run around in and looks good from 20 feet away, during the swap we lowered it with a
DJM 4/6 kit, donor drivetrain is from a 05 model avalanche, I swapped over to the cable drive throttle body to make things more simple. I bought my harness from nelson performance,fan harness and comp program by them also, if anyone has any questions about the swap feel free to ask, I took some closer detail pics
on the a/c bracket and fuel line setup to give those who may be working on a swap, I could not be happier with how this swap turned out, 2 thumbs up to this site and 2 thumbs up to Jon at Nelson Performance!!

Big Thanks to my friends Chris, Keith and Bill for some odd and end parts and help getting the conversion complete!!

Thanks, I just gotta do something with that upper radiator hose, that coupler looks like crap to me

Did your factory Y pipe bolt right up to the new exhaust manifolds? If not what did you have to do? Thx

[1991SSP]

No, I just bolted up short pieces of the stock pipe coming off each manidfold, they saved them for me here at a local yard so that I'd have enough to bolt in my 02 sensors, The drivers side was right against the frame, the exhaust shop took the stock piece of pipe off the manifold and made a cut on the backside of the pipe, reinstalled it back on the manifold and used a bar to bend it away from the frame, then took it back off and patched the opening with some scrap exhaust, he was actually pretty creative and it looked good when he was done with it, from there it's a true dual setup with X pipe section and bassani mufflers and bassani tips

Very clean install looks good, I know that once the swaps all finished it's a big relief. Enjoy your new ride..

thanks for the compliment, it's a blast to drive!! I have yet to check on the highway mpg but for now the mileage that it's getting running around town is alot better than the crap box 4.3 got

Isn't that amazing? How a V8 can get better gas mileage than a V6 (or I6 for that matter) is beyond me. Technology is a great thing!

I am sure you know but that nipple on the radiator is threaded on the inside.
