Q&A WITH KOLBY ENGER FROM TURN KEY SUPPLYCHP: Walking through your facility was almost a mirrorlike experience to walking through a GM warehouse. What are the bulk of the builds you do on a regular monthly basis?Kolby Enger: Our primary sellers are the 450- to 500hp versions of the LS1s, and more recently we're starting to see more 500-plus-horsepower LS2s with forced induction going out the door.CHP: Are you noticing any kind of trend in sales with the LS-series engines? KE: A lot of guys out there are building musclecars and outfitting them with modern-day components, including the suspension and drivetrain. Lately, we've been selling an incredible number of LS engines with retro kits that'll allow for a perfect fit underneath the stock hood while utilizing the existing motor mounts.CHP: Is there a particular combination that outsells the rest?KE: Our engine-swap kits for '67-69 Camaros and '55-57 Chevys seem to be really hot right now.CHP: What is it about the LS engines that you prefer over the older conventional small-blocks?KE: There are a few things, such as the aluminum construction and the bottom-end torque, and while the carburetor versions work well, we're partial to the electronic fuel-Injection setup. The EFI system we offer is fully programmable and capable of tuning any combination a customer can dream of. If a customer wants an out-the-door twin turbo system that can produce over 1,000 hp with a tune, we can do that too.
