The podcast they do kinda spoils the ending.

Basically, it was build a sub 500 cube steel roof and quarter car. One of the show characters had to drive in the car they built, 66-72 american car.
Monkey took a free challenger they had donated from dodge and hung panels on a chassis that was already built (aka brought over from the prostock team richard owns). The prostock team built the car with parts they had on the shelf and it was driven by the prostock driver. Monkey shop had their guy's show up in the episode and look like they built stuff but the prostock team did everything.
Basically a repeat of the Roadkill episode. Build to these rules, except not and totally overdo it because winning is more important than having fun.
Street guys bought Palbykin's old 90's chassis which was a awesome car but still a promod. Threw on parts they had laying around to bring the show back to the roots.
It's a ratings ploy basically. Monkey was decent show when it was just a couple guys in a shop. Now its a giant conglomorate and lost its edge. Same with the american chopper show.
Fastnloud will go the same way as the tuettels did in american chopper. Spend a ton of money on marketing and overhead and have discovery support your lifestyle. Show leaves and so does the money. At least the SO guy's have little to no overhead once the show leaves.
I watch SO when I can mostly because Shearer's pontiac engine build is awesome. Running that fast on a production cast edelbrock head and what was a production iron blocked filled is insane (ive seen billet block pics floating around). You could replicate that engine he ran a couple years ago with a 455 block and a summit/butler catalog. Run radial vs. the world on production pontiac stuff is super cool.
