The "new" small block Chevy...LT1!

So, Chevy is launching an all new small block. It replaces the LS series and nothing swaps between them. A new era is here! http://www.enginelabs.com/news/breaking-news-chevy-gen-v-small-block-reveal/ So...here go..again!

Dang, just get the LS stuff working and I'm obsolete again. razz  Really surprised they stuck with a pushrod engine again, but it seems to work for them.  I just wish they wouldn't keep reusing the engine designations, hard enough to keep them straight, but reusing LT1 will make it more confusing .

Yes, reusing past engine designations is very confusing and frustrating. Is this the third LT engine series or the forth? I really thought they would go with the overhead cam and possibly a different fuel source this time.

So let see, it will take a couple years to get this into production, that’s if the government lets GM build it, then a few more years before they start becoming available in the second hand or hand-me-down market. Then a couple more years for the aftermarket parts manufactures to get their stuff ready and on the market.

That means AJ Kiefer will be installing one in the blue 69 we saw in the shop last weekend with a 10 speed automatic transmission to replace the three speed manual.

I'm glad they're sticking with those "Rube Goldberg" pushrods... keeps the engine overall size easier to package into retrofits. nana

I think they need to keep the pushrods because of the Variable Valve Timing. I know other manufacturers are doing it other ways and maybe GM is working on a different solution.

I'm just glad GM is using some sort of designation since otherwise people would be coming in to buy parts with the whole "They're all the same" thought again, and then I have to break the news to them that they need to figure out what they have.

"Officials just announced no further research on LS series engines."

Wow, that supprises me that they are moving on from the LS engines so quick. I would guess only a few more model years before the LS engines are complete history in production vehicles then.

I wonder how the aftermarket will react?

They all kind of abandoned the Gen 2 after the Gen 3 stuff really took off.

With any luck it will drive down the prices on Gen 3 & 4 stuff.  I think maybe the Gen 2 stuff got abandoned quiker because they only had a 5 year run.  The Gen 3 & 4 stuff has been around in some capacity for 16 years.

Dart has also announced a LS block with Gen I bottom end... Uses the Better breathing LS head but with the stronger Gen I bottom end... I only wish it was available in Aluminum and could accommodate a 4.25" stroke.

The LS engines have been in production trucks since mid '99, and the corvettes since '97. Not a bad run considering all the variations and the total amount of vehicles they have gone into.

If anything, GM stopping research will help the aftermarket since there won't be constant changes that will create even more versions that aren't interchangeable with what's out there. I'm waiting to see more about those Dart heads, that looks like it might be a new variation on the whole thing.

 I think this has already been done before. I remember seeing (somewhere) a Gen 1 block cast with LS deck surface to accept LS heads and intake. It was different then the Dart version. It was all Gen 1 with just the deck and intake area LS shaped. Maybe World Products?

I believe the bore spacing is different on the LS stuff vs Gen 1 as well .  I think they actually use small block F*rd plates to hone them.

Is it really going to be considered a "small block" if there isnt a big block to differentiate it from?
