"Classic Series" 300 HP
(Stage 1)
If you want to replace or upgrade your existing hot rod or muscle car engine this is the perfect choice.
If you prefer cruising the open road rather than the dragstrip, then this is the right choice for you. Reliability, drivability, smooth and balanced are a few words to describe this engine package.
With adequate power and that iconic v8 exhaust note, it lets passersby know that you don’t just have a stocker under the hood.
Modern upgrades inside such as a roller camshaft and lifters, with classic styling on the outside, this engine is a tribute to over 60 years of small block history.
