Tri-power Rochester Model BC Chevy 235 Six
This is 3 carb set-up on a Chevy 235 inline Six. This intake is an Offenhauser for the 235. The carbs are large base Rochester BC's. The automatic choke is fed from a copper tube heat riser that extends into the Exhaust heated base. The tube exits the heated cavity to the atmosphere (does not pick up carbon from the Exhaust). Fuel line is plumbed entirely in solid brass pipe. The engine is 1959 vintage 0.60 over with the late high compression heads. 3/4 cam with mild lope can be heard in the video. Exhaust is temporarily fabbed outside the split Fenton Exhaust manifolds...so sounds a little odd with my little digital camera. Sounds a lot better in person!

GM 216 Straight Six Blowing Up & Catching on Fire
To all the angry viewers out there, please feel free to post your comments below and thanks for watching! Blowing up the engine was really fun, and we would't think twice about doing it again. For all the other viewers who enjoyed the video, please post your awesome comments below and thanks for watching! The engine had not run for a number of years and was scrapyard bound so after sanding down the points and giving it some fuel it ran wide open for about 10-12 minutes before it threw some rods, the oil caught on fire and ran out of fuel. http://youtu.be/mWcMA1zfp64 [A video of the 216 running after sitting for an unknown number of years] http://www.youtube.com/user/Toylar

1966 Chevy 250 Inline 6 Start Up
Here is the second video of my 1966 Chevrolet C-10 starting up. Since the first video, I have had the head professionally machined and rebuilt, which included new valves, valve guides and oil seals, hardened Exhaust seats, valve springs and retainers, and new rocker arms. The head was also shaved to level and the manifolds were evened out. I also replaced a bad accelerator pump in the Rochester B carb. that made the engine nearly impossible to start when cold. Now it runs like new and pulls better than ever.
