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!

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.

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.
