Chevy engine

How many out there know that Chevrolet has NEVER produced a 396 cu.in. eng????? :Brow:

 

402.

 

What was changed? Bore? Stroke?

 

Ouch

:laugh:

 

396

I do know that when the tech crew would run the cu. in. test at the drag strip they would always check out to an eaven 400 inches. I read later that the chevy execs liked the phraze "SS 396" and coupled with the 400 in.ban at that time decided to go with that. Kind of like Buick calling a 401 a 400.

 

C=can
H=hear
E=every
V=valve
R=rattle
O=on
L=long
E=extended
T=trips

:eek2: :Smarty:

 

Exactly what they said on American Muscle Car or one of those shows.. 402.

 

C = CANT
H = HANDLE
E = EVEN
V = VOLKSWAGONS
Y = YET

o No: :3gears: :Brow: ou:

 

Nope, they snuck right under 400 ci fair and square:

Bore = 4.095"
Stroke = 3.76"
4.095 x 4.095 x 0.7854 [<-- pi/4 ] x 3.76 x 8 cylinders = 396.1

Like a bunch of others said, the later ones had a 4.125" bore, so they were 402's.


Also, you know the magazines always call a .060 over 454 a "468" ? It's actually a 467. I know it's small and insignificant, but I guess that's why it's always irritated me that they can't get it right.

4.31 x 4.31 x 0.7854 x 4 x 8 = 466.9

If you have to run a Chevy big block,427 is the way to go. 396's were ok,but the 427 was much better.

The only exception to the 396,was the L-78 which was rated at 375 hp,but power output was around 425 hp. Those L-78's were good running engines.

 

Ya, the Buick 455 is much better! Except the weak mains, lifter valley, large mains, aluminum oil pump housing, small cam journals, thin cylinder walls, no forged crankshafts, non adjustable valve train, and rope seals! I love my Buick because they are different and powerful. I just cant stand when people knock a greatly designed engine. When Chevrolet Designed the small and big blocks they had their sh-t together. Some engines are "boat anchors" but not this one, 396-375hp was a great engine.

L-78

Had one of these in my 71 chevelle SS, That was one awesome motor !!

 

Hey Guys.Chevy big blocks are pretty good engines all around.I don`t think the 396-325 h.p (base engine)was a very hot package. :boring:This was what 60-70% of the Chevelles probably came with.The L78 with solid lifters and 780 Holley proved to be the "Real" 396.Other than that the SS396 Chevelle is a bit over rated IMHO.In the late 70`s I street raced a few with my 340 Dart and had no problem being the victor!! :grin: Later,Tony.
