building 273..or not

The 273 potential is there. I put a 4 speed in a 4 door 1965 Valiant and ran a best E.T. of 12.72 at about 108 MPH. The car weighed about 2960 lbs and used a 4.56 rear end with 10 inch slicks. The other equipment and specs were: bored .060 over (282 CID)with 10.5 pistons (TRW), 312 duration cam with .580 lift (ISKY), Holley 600 CFM double pumper on a Tarantula manifold (Edelbrock), cool can in fuel line, Holley electric fuel pump, Cyclone fenderwell headers, stock heads ported and polished with a dremel tool, bearing clearances set at factory maximums, super stock leaf springs, relocated battery, VW front tires, Chrysler electronic ignition, manual steering and brakes, old orange flex-a-lite competition cooling fan with the stock radiator, and engine components balanced. After a short burnout in plain water (using second gear without a linelock) the car was launched at 6000 RPM and shifted at 6000 RPM with a trap speed on the best runs about 6400 RPM. This was taking place at Fremont Raceway back in the late 1970´s. The car was street legal and street driven until it was sold to the Renteria brothers in 1980 who then spent a few million dollars turning it into the quickest 4 door Valiant in the history of the world. I guess I could consider myself the grandfather of it all, after having purchased the car for $125 with a burned valve back in 1973 or so. Please continue the 273 tradition of blowing away bigger motors.
