6.2 pedigree

[robnfl]

Engine displacement is determined from the bore and stroke of an engine's cylinders. The bore is the diameter of the circular chambers cut into the cylinder block.

Displacement = Bore(squared) x 0.7854 x Stroke x Number of cylinders

Displacement = 4.02 (squared) x 0.7854 x 3.74 x 8

Displacement = 379.7559 = 380cuin

Here ya go Cleave, I found an extra cubic inch fer ya

I still think 6.2L sounds better...
Inches are so....trying to be special...

back on the main discussion what does the future may hold :

So loking at Le Mans they are running hybrid diesel electic systems
High horse engines that have 500+ hp
Added to high torque electic motors

Or systems like the porsche 918

I would love to see that in a baja like truck

It is complexer then just an engine
What do you guys think of haven the an hybrid setup?
With still the power or even greater then the 6.2 has nowa days

If they can get a better or just as good sound i would be happy. Thats one of my favorite parts, that hell raisin' 6.2 V8

Just curious, why do you care?

To answer your question, it's neither. The Big/Small block classification is based on the external dimensions of the block. So a 396 Chevy is considered a Big Block and a 400 Chevy is a Small Block. Displacement is not the determining factor - even though big blocks tend to have a higher displacement of course.

Small/Big block terminology is used when the manufacturer offers both a larger and smaller exterior engine design. So to use Pontiac as an example, since all of their V8's had the same exterior dimensions, a Pontiac V8 is not referred to as a big or small block. Just try to find a die-hard Pontiac Enthusiast that calls a 455 a big block....you won't.

I just want to get my nomenclature correct., all the Fords I've ever owned have been diesels, so i grew up on Chevys, I understand how Chevy had different block sizes that didn't always hinge on displacement, just like you said, 396 big block vs the 400 small block.
I am not as familiar with the Ford gas engines and didn't know if or where they made a split to a bigger block size. Like I assume a Ford 460 is a big block size.

And what does Boss indicate if anything, other than just a name?

I remember the 351 Cleveland vs the 351 Windsor from the old days based on where they were made but that's about it.

I beleive boss stands for bored out short stroke

Think its part of the following qoute
Its about BIG in/outlet ports of a comparably smaller engine

[qoute]
The Boss 302 engine was a hybrid of small-block Ford V8s. It used the block of the small Ford Windsor engine and the heads of the larger Ford Cleveland engine. It was created for the SCCA's Trans-Am road racing series, and was fitted to the factory-made Boss 302 Mustangs of 1969-70.[1] There is a conflict between the actual displacement in cubic inches and the advertised metric displacement.

The high nickel content block has a thicker deck, cylinder walls and 4-bolt main caps. It is identified by screw in freeze plugs on the side of the block, pent roof valve covers, wide heads, and a wide intake manifold. The Boss 302 has eight valve cover bolts (because of the Cleveland heads), while the standard 302 has six. The connecting rods are heavy, high strength steel forgings made for high rpm use. The crankshaft is a cross drilled high strength steel forging. The cam and lifters are high lift solid mechanical units.

The wide and large port Cleveland-style heads with staggered valve placement give the Boss 302 high power capabilities. Early units were typically characterized by very large intake and exhaust valves sitting in a small quench style combustion chamber.

The motor produces a unique sound as a result of its solid lifter configuration. At idle, properly tuned, the engine has a great deal of 'chatter.'[\qoute]

Solid lifter cam lope=instant ***** dropper

Solid lifter cam lope=instant ***** dropper

Haha

Its because of the idling chattter...
Its like james brown ... deep voiced ***** peeler

A lot of people referred to my Z06 7.0L (427cid) LS7 engine as a big block when it is really a small block Chevy engine. Just because of it's displacement size.
