Makes an old fanatical mechanic car builder remember so much while I literally lay here with a broken back. My favorite build was putting a 409 in a '64 Nova SS. It was a good build cause a 409 is just a few inches wider than a small block and less than fifty pounds heavier than a 350. For suspension and brakes....everything from a '64 Nova wagon. I creep on the cheap. Yah, a dual quad 427 has 435 hp, a dual quad 409 has 435 at allot less weight and in a late seventies Nova...get out of here ! Putting a small block Ford 351 (from a Ford Ecoline van) UT-10 4-speed (from a Mustang) into a Mercury Comet cause the car holds the road better than a Mustang. Found an ugly '65 Dodge Cornet SS 413 car and slapped the 440 head/tri-power intake combo getting 450hp, the 413 has a forged crank good for an 8000 RPM redline after installing an oil cooler, then the car was so light and handled well....hated selling it !!!
