Chevrolet 7.0-liter LS427/570 crate motor tuned past street-legal

GM’s 7.0-liter LS7 V8 might best be known in production form as the heart of the C6 Corvette Z06, but the naturally aspirated base unit has been a very popular crate motor. In a 2008 Hot Rod piece that put eight GM crate motors to test at the drag strip in a 1969 Chevelle SS 396, the 505-horsepower LS7 was only bested by the 640-hp LSX454 and the 720-hp ZZ572, all of which ran in the tens. Since then, ease of use and kindness to tuning has seen the LS7 tapped to power six- and seven-figure supercars like the Falcon F7, Savage Rivale GTS, Ultima GTR, Mazzanti Evantra, and Zenvo ST1. Now Chevrolet Performance has improved the original with the new LS427/570 crate engine, upping output to 570 hp and 540 pound-feet of torque, representing 65-hp and 70-lb-ft increases.


At auction, Ford designer nabs concept car he previously worked on

For car designers, falling in love with your own work, we imagine, must be an occupational hazard. When that work is a production car, the easy solution once the model reaches showrooms is to go out and buy one — taking advantage of friendly, employee pricing. But when your Rembrandt is a concept car, usually after its auto-show tour is done it disappears into an automaker’s warehouse or, worse, ends up being crushed. The Ford Via concept car escaped both of those fates and eventually wound up on Bring a Trailer, where it caught the attention of Moray Callum, one of the designers who originally worked on the project.

During the auction, Callum posted a comment on the site giving the background of the Via. The objective was to show a cab-forward design for a proposed
