Big Block Nick Name


When the Mark II 427's debuted at Daytona in February 63, in Junior Johnson's 63 Impala and Mickey Thompson's 63 Z06, they were initially known as the "Mystery Motor". Later, after people saw what the engine and heads looked like, they became known as the "porcupine".
As far as big blocks being boat anchors, the three fastest cars around here when I was a teenager, were a pair of 396/375 Nova SS's and a 70 LS-6 Chevelle. Those three cars were in a class by themselves, and not much could touch them on the street, including most Street Hemi's.
Big blocks like 427/425 Vettes, 396/375 Chevelle's, Nova's and Camaro's, and LS-6 70 Chevelle's, were very fast, but were pretty rare, even in 68-72. The much more common, low horse 396/325's were dog's, especially when installed in a Chevelle with an automatic. A 350/300 Nova or Camaro beat them easily, and a 350/300 Chevelle, could give them a good run.

I have a stock 396/375 Nova and it will not beat my first generation Chevy II with stock L 84 engine due to factors I've mentioned above. But neither would the one Street Hemi we had here.

The Best of Corvette for Corvette Enthusiasts
I started to help you out with this yesterday and then I canceled my post.

I figured you were big enough to row your own boat.
Some read the thread title, none of the subsequent posts except the last one and then wind up coming off with...................., well, you know!

Goes back to that recent rant on here about people not reading all the posts in a thread.
[/QUOTE]I disagree. Every 325HP 396 I drove, worked on, or raced against ran like it was tied to a tree when compared to 275-350HP rated small blocks of the same era. Absolute dogs. Not the 375HP version, but the 325-350 396 engines haven't impressed me.....ever.
The 325/396 would respond very well with 9.50 X 14 M/H and a 396/375 cam and headers would run very well in a street drag race.
But, that is getting off topic.

my bbc drag motor is setting in the corner of the shop waiting for the new car! my best time with it was 8.18 at 178 mph. it made 1698 hp with a lean carb the last time on the dyno at 7800 rpm a 1000 rpm under my shift point. with proper jetting it will go past 1800hp I am guessing! its a de-stroked 4.500 bore prostock block with a 3.00 stroke crank in it. it sounds like a girl screamin bloody murder when it winds up

yes I love my bbc's but probably my fav was my rally green whit int, 69 z/28 berger chevy 302 radio/heater delete crossram car. I sold too buy the family farm. it loved the high side of 8000rpm. I wish I still had it. it pops up for sale once in while in hemmings and ebay but way out of my life price range now..RPM RULES! troy

Any reason you destroked it so severely? Why not something between 3.5 and 3.75? Extra $$$ would buy the parts to handle the higher piston speed. Not a criticism.you develop immense power from only 382 cubes. Is it "all engine" and normally aspirated?
With my 327 it just spins wheels. It will spin forever unless I get out of the gas once it breaks traction.
...............and THAT'S why I'm not a big torque fan. Horsepower rules!
