The 1970 Chevy Nova was a pretty good car, simple and quite versatile; you could get one with a gas-sipping 153-cube four-cylinder engine, a hoon-a-pa-loozic 396 big-block, or just about anything in between (though the standard 307 was sort of a dud). Not only that, it was a better automobile than O.J. Simpson... who seems angry at the suggestion that the Nova is cheaper to run than he is.
I put a Weiand aluminum split plenum intake, pretty mean camshaft, holley double pumper 650, MSD high output ignition, GT40 headers and Bowtie fast burn heads on a 307 and....AND........it wasn't very impressive. Sounded sweet though. Luckily the car it went into was only 2000 lbs so it worked well enough.
