1st Gen Lunchtable Thread - General Discussion

Morning all.

 

Boy, all you had to do was attach them

 

1uz is even cheaper

 

That was like 3 years ago

 

I know i know, had to bench everything after having a fall through with the gf. promise ill get on it

 

Lighter and more stout in the rotating assembly too. But I think the 3UZ is the best value in power, weight, and upgrade path.

 

350k junkyard silverado LS FTW

 

when its noisy does the fluid look foamy/aerated?

 

Yeah that can be fun too, not stock, but with a cam, intake, and a cheapo tune.

 

I love the sound of UZ swaps with basic cheap turbo style mufflers

 

Technically a junkyard engine...

 

that is a clean fit

must be a fun driver too

 

It's pretty entertaining, but not super fast yet. It's an all aluminum LH6 5.3 with a brian tooley racing stage three truck cam. Needs spicier tune, I have the ignition timing map set pretty aggressive but I'm 90% sure that carburetor is holding it back.

Why didn't you go with EFI again?

 

Because my buddy who I did all the wiring and much of the assembly with is afraid of EFI and thought he was going to have to wire it all. I would have been happy to do it cause it would easily be 75+ HP more and a ton more under the curve where the carb is responding poorly. This dynod with its poop carb tune at 262hp at the wheels, thats through a 700R4 and with 285/60/18 tires and a 3.73 axle ratio. So it's maybe a 330hp engine, it should be much better than that.

 

No foam. I can see the fluid circulating in the reservoir as it should. I can feel the whine vibrations being transmitted through the larger supply hose. When I turn the wheel slightly the whine stops for a few minutes. Sometimes when I make clock-to-clock turns the steering becomes jerky and the while really gets loud -- but not every time.

 

Sounds like you will be swapping to EFI either way eventually. I see no reason to run carbs on anything any more unless you are trying to keep a restored vehicle 100% stock.

 

I offered to do it for him, we have three other assembled LS engines with carbs on top and I told him now is the time to learn and plan, cause otherwise you have two (much more expensive engine swaps) that are also going to disappoint on deck. Even a TBI kit would perform much better, but ideally I'd like to warm him up to MPFI, and hell these LS engines are ready for it all anyway, we still have stock truck manifolds that I could demonstrate on.

 

Yeah, there are a ridiculous number of options for the LS when it comes to injection of any kind. Not super hard to do any more, I have no doubt there are complete plug and play kits for most anything with hardly any real wiring to do.
