lsa engine

So I have always loved the classic and retro cars I have owned, but equally I have loved getting to know them just as much. (what is a car if you do not know it). So I was trying to research the specs on the Lsa engine, and there seemed to be two answers that kept coming up as the proper Cubic inch displacement for the Lsa engine in the Zl1. I read 376 and 378. Anyone know the right answer and why?. Also Did the original Zl1 come with a 427?, if so why didn't they put that engine back in?.

376 I believe is right. The original ZL1 cars were indeed factory fitted 427 big block monsters. Completely different engine and platform. My first car was a 1969 396/325 SS Camaro. I was 16. It was 1979. I paid $1200.. Back then it was just a car with a little rust on the quarter panel. It probably ran high thirteens low fourteens. The point is technology. They can make more power with less cubes.

I saw an online video about the hellcats motor consuming 1.5 gallons of gas per minute at wot, so I suppose the ability to do more with less cubes is a great thing. Any idea how the Cubic displacement is calculated on a engine?. btw nice car.

How many liters in 1 cubic inches? The answer is 0.0163870640693.
We assume you are converting between liter and cubic inch.
1 cubic meter is equal to 1000 liters, or 61023.7438368 cubic inches.

The hell cat motor is the same size as the LSA, 376 cu inches.

Cubic inches or litters

Multiply area X Traveling ( height )

There you go

Or, taking the equation above and putting it into automotive terms:

Bore x Bore x Stroke x Number of Cylinders x .7854 = Size

Or for the LSA:

CI:
4.06 x 4.06 x 3.62 x 8 x .7854 = 374.9225

Liters:
103.25 x 103.25 x 92 x 8 x .7854 = 6162.39 / 1000 = 6.162

Historically, the new ZL1 would have been better named SS and the current Z/28 with a 427 should be the ZL1. In the past, the SS nomenclature was for upgraded cars, not simply the 8 cylinder version of a Camaro. The current SS would have been called the Z/28 in prior generations.

Perfectly expressed.
