[Shotimes] Power adder discussion (I went really OT)

[Ron Porter]

Uh....no.....no one cares!!

Pro Street cars are pretty much in the Custom Car - Street Rod genre. Not
that "some" of them aren't quick (and many are definitely "show only"), but
there's a lot of other street machinery out there that can clean their
clocks. 

Pro Street with all of the trimmings is a subculture like street rods or
lowriders. Not of interest to most serious performance enthusiasts.

We've built a lot of Pro street cars with 383/ 6-71 combo.  The last one I
was involved with building dropped a valve at 4 grand. :-)

Time restraint has stopped me from continuing to play with the hot rods, but
I still go to the club meets and look at the finished products.  The sound
of a 383 with a 6-71 coming over the roof of the car is a beautiful.  I got
my start in cars with small block chebbies.

Does anyone really care? :-)
