It's starting again someone picked this 413 thread out the trash from a YEAR ago.... If we're going to drag ALL the 413 threads back out AGAIN... Mods can we PLEASE have the :horse: smiley back

Someone alert the usual 413 cheering section... here we go again

---

It seems that every time there is factual info
placed on the board about 413's, some people
get very nervous and frustrated. I guess some
people cannot relate to Mopar BB with less than
4 1/4" bore. It is not a putdown, it's simply an
observation. "Runner", the post was simply a true
statement, given by the R&D Engineers from
Chrysler, who were also pro racers. These honorable men were the basis of the 413/426
Superstock/Max-Wedge program. They were known
as THE RAMCHARGERS. Honestly without them, the
Big Block program in the later years would not
have been as STRONG as it continues to be.
Lighten up man, and learn a little more. There
is more to posting besides .

its amazing that useful knowledge is actually provided and transferred.. i mean with everyone thinking they are smarter than the other person.

i, for one, know i am not smarter than a lot of people. i can respect everyones knowledge, but couldnt you all just have ended this thread with this:

the 413 can be bored to the 426 specs, but you have to sonic test it to ensure there is no undesired core shift.

boom.. the thread can end.

It IS NOT the point of everyone thinking they are
smarter than others. We are all trying to "share"
information. To learn from one another opens up
new ideas in ways to make more power and run
better times, maybe get a better deal on parts.
You never know. And I, do not think that I am smarter than the next person. If I have useful,
factual knowledge, I try to share it with those
who are willing to listen and research also. If
they have info. then I would listen and research
on the topic also. Nobody knows everything, and
if they did they would not be mortal.

You spelled "thinks" wrong. Not cool to bust on people for spelling when you can't spell on your own. You also failed at capitalizing some letters elsewhere in your reply. But I'm just messing with you all. What's spelling have to do with knowledge of an engine?

---

Hey Goo$e ...who rattled yurr cage ? ..

That misspelling ? ...was done on purpose. "Proper" English would be .... I think so. Same/same as my spelling of the word that I use for BETTER ... best-er.

JUST a style of writing.

Now to be ON TOPIC ... take a tip from guys who know-more about 413 and 426 blocks than ALL OF US .. put together...

Talk to any stock-eliminator guy who runs the 413 or 426 motor .... they all go with the motor home/truck block ......

BECAUSE it is BESTer !

I believe that you are right about the Stock
Eliminator guys using truck/industrial blocks.
They are bound by rules in that class by the
engine size to be competitive at a certain level.
Change the engine, you change the level you are
running in that class. Thanks Doc, not a bad
post, they should not worry about your spelling.
Most of us do know what you are talking about.
As for the they have their place and refuse
to learn from others. Don't waste your posts on them.

Isn't an 8 bolt flange considered akin to the
HEMI mill.

I always thought the rule of thumb was .060 is the safe limit, anything beyond that, sonic check it.

of course, never say never, if you sonic check is first, then you'll always be safe

---

Very good point! Know before you punch the block.
Best way. Or play the safe route, but $$$$, hone
and put custom pistons (4.18) in it. Owners
choice. Or, even safer up the ante and run a
440 block. Lots of options here!!

Yes, but the early 383RB's and 413's also had an 8 bolt flange, they earned the slang name "413 truck cranks" some time ago but that's not an accurate description as they were in passenger car 413's as well. They were about 3/8" longer at the flange than later 440 or Hemi cranks, they bolted directly to the converter and used no flex plate. They could bolt into a later engine, but the flange extended back too far to use with a late model flex plate & converter. When I built my 1960 413 engine (original 300F Long Ram engine) I swapped the crank to a later 6 bolt so that I could run a 1965 727 behind it.

---

Great tech! I was kinda fuzzy when it came to
those 8 hole cranks in the RB mills, thought that it was a durability issue. But thanks for bringing
it to light and clearing the issue. Thanks again,
this is one for my "archives".

Somewhere I have in writing stated by the "real" Larry Sheppard,retired Chrysler Staff Engineer who was responsible for the early Direct Connection Performance Manual that the only 413 block that can be "safely" bored to 426 is the 62/early 63 Max wedge and medium duty truck block.It can and has been done with others but you are taking a chance."If" I can find it,I'll post it.However,I'm sure there are still experts here that will dispute it.

Just to let you know that there is only one
Larry Sheppard, so you do not need to refer to
him as the "real one".

Maybe you're right Doc. Just remember
to leave me one of those blocks also, when you
start "scooping them up". And I know "Ghost" may
take a couple !!
