What is the difference between 8 valve and 16 valve?
Well 8 valves (8v) basically means a 4-cyl engine with 2 valves/cyl (one for intake and one for exhaust). 16 valves (16v) means 4 valves/cyl (two each for intake and exhaust). The 16v engine is better in terms of performance as it has an easier time taking in air and pushing out exhaust (i.e, breathing).
Is 16 valve a V8?
A 16 valve engine could either be a inline OHC four cylinder with 4 valves per cylinder or it could be a V8 with 2 valves per cylinder such as many American push-rod V8s.
What cylinder is a 16 valve?
An EFI 16-valve DOHC is a four-cylinder engine with four valves per cylinder, dual overhead cam and electronic fuel injection. Most engines with these features have a displacement of 2.4 liters or less. The engine is the smallest for most European, Japanese and North American cars.
When did Ford change cylinder heads and valvetrains?
Beginning May 2, 1966, Ford changed both cylinder heads and valvetrains on 289 engines. Prior to this date in production, Ford had pushrod guide holes machined into the castings. However, from May 2, 1966 on, Ford found a cheaper way to make 289 engines.
What is the valve size on a 1967 Ford high performance head?
Valve and port size is identical to 289-2V/4V heads. The 1967 289 High Performance head has slightly larger ports with the same valve size. The 221/260/289 combustion chamber looks like this, wrapped tightly around a pair modestly sized intake/exhaust valves.
What to look for in a small block Ford cylinder head?
Small-block Ford cylinder-head identification is straightforward if you know what to look for. In time, it becomes second nature. The most important clues are Ford casting numbers and date codes, and understanding the difference between a casting number and part number. Rarely are the two ever the same.
What kind of valve springs do Vortec cylinder heads use?
Our heads come with special high-lift dual valve springs with dampers, built to work with our high-lift series of camshafts and use CNC chromoly retainers. Instead of rubber seals, these heads feature viton valve stem seals for added durability.
How big is a Victor small block cylinder head?
Victor Jr. heads have 210cc intake runners and 60cc combustion chambers; each is designed for 2.05/1.60-inch valves and can be ordered bare or fully assembled with 1.55-inch diameter valve springs. These oversize springs allow you to use a flat-tappet camshaft with lift ratings as high as .670-inch.
What kind of cylinder head does a Ford small block use?
Both the ST 5.0 and KC ST 5.0R heads are available bare or fully assembled, and individually or in packages. Brodix also offers Track One cylinder heads for racing applications. These aluminum heads feature 195cc intake runners and 68cc combustion chambers. Optional 211cc and 225cc intake runners are also offered.
Can a cylinder head be installed on an LS1 block?
Basically, you need to pay attention to the block’s bore diameter. Running a cylinder head intended for a larger bore size can result in valves crashing into the block. For instance, you cannot install an LS3, LS9 or L92-style head on an LS1 or LS6 block due to valve interference with the block deck.
What kind of valve cover does a Chevy cylinder head use?
Although Gen V/VI heads retained the original valve cover bolt pattern, their matching cast aluminum valve covers were equipped with a durable rubber O-ring in place of the traditional valve cover gasket. All production heads use the same intake and exhaust bolt patterns, which include a bolt-hole between each pair of intake ports.
