What size is an LT1 engine?
Engine Block Specifications The LT1’s iron engine block is sized at 350 cubic inches and has an overall displacement of 5.7 liters. It has a cylinder bore and stroke of 4 and 3.48 inches, respectively. The LT1 has a compression ratio of 10.4 to 1 and a maximum rev-limit of 5,700 rpm.
Are all LT1 engines the same?
There are different LT1’s available and they vary in horsepower and torque so let’s make sure we are getting the best one for our projects. To identify a GM LT1 engine, check towards the front of the passenger side of the engine block where there is a machined pad with an 8 digit ID number.
What year is the best LT1 engine?
The high performance, technology-packed LT1 Small Block 6.2L V8 that powers the 2015 Corvette Stingray is a Ward’s 10 Best Engine for 2015. The engine also was recognized with this award in 2014.
What does LT1 stand for?

How big is the combustion chamber on a small block?
Generally, most performance small-block heads used a 64-cc combustion chamber roughly in the shape of a tub. The first major change to chambers came when emissions requirements led to increasing the size of the chamber to reduce compression and attempt to reduce the hydrocarbon count in the exhaust residue.
What was the combustion chamber like in the early Chevys?
In the early days of the smallblock Chevy and for all engines up to perhaps the mid-1970s, the shape of the combustion chamber was merely a tub or vessel in which to contain the valves. Little attention was given to the early small-block chambers other than the chamber volume’s affect on compression ratio.
Why did they change the size of the combustion chamber?
The first major change to chambers came when emissions requirements led to increasing the size of the chamber to reduce compression and attempt to reduce the hydrocarbon count in the exhaust residue. This led to open chambers designed to reduce the quench area of the head, which also reduced oxides of nitrogen (NOx) emissions.
What kind of combustion chamber does a czo6 corvette use?
While offering decent intake flow for its port size, this chamber does little to enhance combustion efficiency. This is a factory LS7 chamber for the GEN IV 505-hp small-block used in the 2006 CZO6 Corvette. Note how the chamber wall is laid away from the valve to mirror the flatter valve angle and the long side radius to improve port flow.
