It may look classic but the engine powering this 1969 Chevelle is all modern. The 1,870 horsepower comes thanks to a Nelson Racing built 509 cubic-inch (8.3L), aluminum big-block Chevy V8. The engine has twin injectors per cylinder, twin air-to-air intercoolers, electronic fuel management and stainless steel exhaust. The transmission is a Mikes two-speed Powerglide with a Gear Vendors over-drive. If you are interested in buying this beast, Nelson is listing it for $125,000.
