250 chevy inline dyno testing
This is one test being done on a Chevy 250 to find out what performance
gains are found with different cams, intakes, heads and Exhaust upgrades.

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!
250 chevy inline 6 in 65 Chevelle wagon lump port head
This video was made to show how a street modified inline 6 can run. The cam
and compression are street fuel friendly. Car weighs in at 3600 lbs empty.
2.56 rear gears
Mileage is 20 MPG going 75-80 MPH
I have owned this car since 2004. It sat in the garage waiting for a
purpose. It had a 194 inline and a powerglide trans with 3.08 gears.
In may of 2012 we decided to get it ready to take to the Inliners
International Convention in Carson City Nevada.
The 194 and trans were pulled. The 250 Dyno engine was installed. This
engine was a Dyno mule
to test different cams, heads, intakes and a turbo in my other videos. It has over 120 full
throttle runs put to it on the Dyno. The trans is a Richmond
non overdrive 5 speed. Rear gears were swapped to 2.56 for highway running.
The engine is a 250 Chevy with flat top pistons, balanced lower end, offy
intake. Compression is 9.5 to 1. The head has extensive work. Bolt in lumps
are installed along with 1.94/ 1.6 valves. The head is also ported. Cam is
a Clifford 270 hydraulic. This engine Dynoed at 285 HP with a 4 BBL
and Clifford intake.
The Exhaust consists of Hooker
headers, dual 2.5" collectors merged together into a Magnaflow 3 chamber
muffler, the tailpipe is 2.5".
Since installation the car was driven to Carson City at the end of May
without trouble. And up to this point has been driven 5500 miles.

Hot Rod Six
235 Chevy with shaved head, oversized Exhaust valves, Fenton 2 x 1 intake, pair of
Rochester BC's, HEI conversion, aluminum timing gears, high ratio rockers,
chromoly pushtubes, buick V8 valve springs, Corvette spec fuel pump, and
tubular split headers (open for now). Carbs still need some dialing in.
Will get dual 2" straightpipes soon.
The camera does not do the split six rap justice.
105 hp stock, estimated at 170 currently.
Hot Rod 292 six cylinder
This engine was a collaboration between my dad and his cousin. It's a 292,
.030 over. It's been balanced. It's got JE forged pistons that puts it at
about 10.5:1 compression. It has an Engle cam with 231 @ .050 duration and
.565 lift. The head is a lump port head by Self with Ferrea 1.94/1.6
valves, K-Motion springs, Bill Smith pushrods, and Harland Sharp 1.75
roller rockers. The oil pan is a Hamburger aluminum pan, and the timing
cover is a Frank pattern finned aluminum unit, and it has a custom made ATI
Super Dampner and aluminum Fidenza flywheel. The intake manifold is a
Clifford 4 barrel, with a 2" Super Sucker and currently has a Holley 750
carb on it., This is going in a '37 Ford pickup with a Richmond 5 speed
Igor the inline six - In Car Camera
Harrison Lougheed Racing Don Ness Ford Escot ZX3 7/8th scale and a fully
custom inline six cylinder engine named "Igor". This video was the first
video ever taken in the car, filmed during Qualifying at the Winter
Nationals in March, 2011.
Turbo Rat Rod Truck at I-40 Dragway
Footage from first test-n-tune of 2010. This truck is built on a budget
with a mostly stock small block Chevy. The turbo is a Borg Warner S400. Runs a 6.18 on this
pass, but the truck has run a best of 5.97 in the eighth mile. This could
be the worlds fastest rat rod!
