GM Performance Parts to Offer LS9 Crate Motor Next Year

A few weeks ago, we pointed you do-it-yourselfers to the "Air Attack" LS7 SC crate engine from Katech. This week, we have news for the purists, in the form of a soon-to-be-offered LS9 crate engine from GM Performance Parts. GM hasn't announced pricing yet, so we don't know if it'll be a bargain or not compared to Katech's $37,000 engine, but if you're planning to build your own ZR1, this engine will look more authentic under the hood. Set to go on sale at the end of summer next year, the crate LS9 6.2L V-8 will come nearly complete. You'll get the engine block and heads, supercharger and cooling block set-up, ignition system, exhaust manifolds, dry-sump oil pan and more. You will, however, need to buy yourself an oil tank for that dry-sump system, a coolant tank for the air-to-water intercooler and an ECU and wiring harness. By the looks of the picture, you may need to pick up an alternator as well. The 638 hp and 604 lb-ft of torque come standard. Source: GM
