Every year we are honored to play a part in the C10 Cruise N’ Show Presented by MO C10 Addiction and being able to give back to the community. This year was our best year yet! We raised $12,275, going to Rescue One and an additional $3,590.50 to Shriners Children's. This would not be possible without our amazing sponsors; QualCast, Enginetech, Engine Pro, P1 Manufacturing and Brian Tooley Racing. Thank you Jason Garrison for joining this with us and adding such fun to the whole event. And last, but certainly not least. Thank you Matt Ford for starting the whole thing and asking us to be a part of it. Cannot wait to see what next year holds!

Check out Monett Motor Speedway this Saturday evening! We've decided to team up with another company to increase the payouts for drivers. Good luck to everyone!

What an amazing opportunity to work with P1 Manufacturing. They really stepped up and help with all of the fasteners for not one but two engines, everything they have to offer for both the small block and the LS. One of these engines we are building could be yours at the 6th Annual C10 Cruise ‘N Show all to support rescue one! Thank you to Matt Ford and the group of truck lovers from MO C10 Addiction (Missouri)

Line boring on a block surfing/boring machine? Why not. Roughed 8n within .0015 how off to the sunnen hone to bring to final size!

it's amazing to see how some shop let this pile of s**t put their door, let alone it lasted long enough to need done all over again, this time the correct way!

Just because someone claims they know what they’re doing doesn’t mean they actually do.
This engine came in with seven pistons installed incorrectly in the block, and the eighth was missing—likely headed the same direction. A mistake like that cost the customer serious money, a ruined engine core, and the expense of a complete rebuild. All because of someone else’s lack of experience and attention to detail.
