Re: [FWDLK] Get your new 392 now!

[Thomas Miller <TFM@xxxxxxxxxxxx>]

Hmmmm.  

The standard 3rd generation Hemi is 5.7 l or around 353 cu. in.  The
SRT-8 motor is 6.1 l.  my math brings that to ~ 368 cu. in.  If it is
the same block, they've poked and / or stroked it out to ~6.4 l to get
to 392 cu.in.  

I'd be astonished if any of the original tooling still exists for a 50
year old motor that was only sold for two years.  I'd be even more
astonished if Chrysler recreated all of that tooling to come up with a
couple of low production crate motors for the Mopar Performance program.
 

As much as I'd like to think it's the "original", I'm guessing it's the
21st century version.  But, I could be wrong too.....  ;-)
