What's the weight comparison of the LT1 to the LS3?

LS3 in crate form is 415lbs
LT1 in ready to run form is 465lbs as stated in the article above.

I'm not really sure.
I guess we'll know when the LT1 is available as a crate engine, but that's a ways off. But I would agree with the assumption that the weight difference is probably negligible.

Hopefully they've fixed the piston slap issues that have long plagued the LS series engines. This engine looks pretty good, I wonder if the days of slapping on a carb on them are over with all the tech packed into them.
They should have given more information in the article such as the flow numbers in comparison with the outgoing heads, the strength of the crankshaft... etc. Also, the V6 is intriguing, but very little info too. |

The Chevy small block engine is iconic and especially exciting with the LT 1 refinements. It is clear that GM has gone all out to produce a very special engine. I am delighted to own an LT 1 (Z51) because of the outstanding performance and it appears that the government will make it obsolete in the not too distant future,.... then it will most certainly become an all time collectors item. For me, too, a special connection to the past; my first car was a new 1956 Chevy Bel Air, small block V8 with power pack. What a car!

Premium octane fuel recommended, but not required. Sweet for those days at the pump when you're feeling like a cheapskate and you won't be driving anywhere special for the next week or two.

BSFC is 330 g/kW.h in normal mode and 270 g/kW.h in cylinder deactivation mode ? how is that possible. it does not look logical to me. when only 4 cylinders are working they still will have to move other 4 cyl.-s too. so the combined BSFC of the whole engine will get worst !

That's what the article mentions, which is pretty amazing. Look at the short paragraph immediately below the photo on the red C6. Premium is recommended but not required. I myself had to run a tank of 89 octane fuel (91 or 93 wasn't available at one point on a long road trip). I experienced no problems, maybe a slight performance drop at most.

This is what I have in the owners manual for octane rating statement. Under what section has anyone found the lower
octane ratings recommended. Fuel TOP TIER Detergent Gasolines. Use premium unleaded gasoline with a posted octane rating of 91 or higher. If the octane is less than 91, you could damage the engine andmay void your vehicle warranty. If heavy knocking is heard when using gasoline rated at 91 octane or higher, the engine needs service. |
