Got my Dec. 2015 copy of Hot Rod magazine. The Dec. issue should be called "Small Block Chevy & Chevy" magazine.
Page 64, a neat little info block titled, "Big-Block Or Small-Block:What Does It Really Mean?" The opening sentence goes like this, "Whether an engine is considered big or small depends on its displacement, but whether it is a big- or small-block is determined by its displacement potential and not its actual capacity.
What in the h*ll does that mean??? DUH!! We all know that a Chevy small block can be easily bumped to the stump pulling 383 cubic inch displacement, right? They sell kits just to do this. So when one ups the "displacement potential
" of the Chevy small-block and "not its actual capacity
" the article writer would then say that the Chevy 383CI is now somehow a Big-Block Chevy. Am I missing something here?????
The HR idiot then goes on to make this statement (Honest, its in print!), "Generally, an engine is called a big-block if its bore centers are more than 4.5 inches and its deck height is greater than 9.5 inches, regardless of its displacement." Aha! So this is how I identify and know its a big block. I'll keep this in mind when I am at my next swap meet.
Hey geeteeohguy, the Packard V8 had a 5.125" bore spacing & 10.065" deck height. Big-block???
HERE's the CLINCHER:
"This makes Chevrolet's 400CI small-block that came out in 1970 a big small-block, and Pontiac's 326 which was a small-bore 389, a small big-block
." I swear, I could not make up this sh*t. I wanna know if Chevrolet's 366CI or 396CI is the small big-block with I assume the 454CI as the big big-block?
HEY HOT ROD!!!!!
The first Pontiac V8 arrived in 1955. All future blocks were derived from this initial design. The basic dimensions, length, and width did not change. It is for this reason that most Pontiac parts can be swapped from engine to engine. Are the small block and big block Chevy engines the same basic dimensions??? Can you swap most of the parts from a small-block onto a big-block?
It is a sad day today as I write this. This absurd quip from some college schooled writer who obviously sits behind a computer in his comfy grey cubicle walled office space covered with those motivational posters, drinking cappuchino mocha, looking in the mirror to check himself out thinking he is "cool," and writing articles about cars never knowing much about them let alone ever climb under the hood of one and get "dirty." And worse, SHAME on the Hot Rod editor who saw nothing wrong with this load of literature crap. The HR editor is obviously NOT a seasoned "hot rodder" or "muscle car guy" who grew up in the era where you knew a small-block from a big-block just from its size/valve covers and you KNEW there was no such animal as a small-block or big-block Pontiac engine.......EVER! ARGH!!!
........and this is where all the Pontiacs are headed, to be powered by small-blocks and big-blocks because after all, a Pontiac 350CI is the same as the Chevy small-block 350CI and the Pontiac 400CI is just a big small-block like the Chevy 400CI, right?
