General Motors' LS-series small-block engines have been in production for over a decade, but it's only been within the last few years that they have really hit critical mass among average hot rodders, who are now finding them to respond superlatively to traditional hot rod power adders. One engine builder that's jumped on the LS bandwagon is Duttweiler Performance, renowned for its hard-running, high-tech, EFI turbo Buick V-6 and classic Chevy V-8 engines. When HOT ROD decided to evaluate the current state of bolt-on LS hop-ups, Duttweiler was our first choice. Its sophisticated Froude F24 dyno controlled by state-of-the-art Digalog Benchmark software enables true wideband pulls, so the facility provided the perfect opportunity for evaluating a late-model engine under simulated street-driving conditions—and proprietor Ken Duttweiler is totally at home with modern PC laptop tuning software.
