We’ve featured Tom Joy’s LSX iron block truck here on ISTR and love seeing it in action.

Some recent footage of Tom’s Syclone #354 was featured at the Street Car Takeover in Maryland where Youtuber BigKlieb34 takes a few minutes to speak with Tom about how he got his truck and how it came about to be a LSX swap rather than keeping the stock 4.3 V6.

His iron-block 6L stroked out 408-cubic inch V8 powered beast, appropriately named “JOYRYDE”. With the help of his brother and their father, Syclone #354 was outfitted with a Turbonetics 91 compressor/101 turbine, Edelbrock intake and fuel rails, 317 cast heads, custom cam, complete with Callies stroker kit. A built 4L80E gearbox with a Moser 12-bolt rear resides between the frame rails.  And the answer is yes, this Syclone is still AWD. Recently added is a custom fabricated carbon fiber flush tonneau cover and rear wing to help with stabilization when clocking 140+mph passes.

Check out the video, enjoy some go fast big block turbo noises, and check back for a future feature on Tom’s truck!
