I love to look at
those brand new pistons
(Silvolite). It's too bad they won't be that
clean once I start running the engine!
The block, with the
heads "installed". The
paint is "Chrysler Blue". I left the intake
off in this picture so you could see the
man-sized intake ports.
The brand new TRW
valve train. I had to
spring for some rocker arm bolts from
Lowe's because my old ones were just too yucky-lookin'.
There she is...over
$1500's worth!
