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. Checkout my website http://www.12bolt.com/ . There are parts and information on how to make your inline Chevy perform.
