The Chevrolet 350 ci motors traditionally have 8 cylinders. There are examples of race-prepped v6 motors that have been built to that size, but those are a rare and expensive item to find.
The 1990 Chevy G20 has a 5.7L Small block 350 v8. So It has 8 cylinders :)
Chevy 305=5.0 Chevy 350=5.7 Chevy 4.3=350-minus two cylinders making it a V6
6 cylinders
have the cylinders bored .030" oversize and fit it with new pistons.
I think it has 6 cylinders.
8 =========================== Chevy's 4.3L engine is essentially their 350 - 8 cyl with 2 cylinders removed, so it is actually a large 6 cylinder engine. Came into use with their Astro vans, and then made it into the cars.
There isn't just ONE freeze plug; there are many, and they're all in the "water jacket" surrounding the cylinders.
If any two adjacent cylinders have low compression it's probably caused by a blown head gasket.
On the driver side of the motor, from fron to rear, are cylinders 1,3,5,7 On the passenger side, from front to rear, are cylinders 2,4,6,8. The firing order is 1.8.4.3.6.5.7.2
It could have 4, 6 or 8 cylinders.
That would be the total volume of all 8 cylinders measured in cubic inches.
2000-2005 have 6 cylinders but the 06 ss has 8 cylinders
