Hello,
I have early (pre'69) and late style C4's built at various levels to handle from 300 to 900hp from $549 to $OhMyGod. Shipping to most places in the US is about $120 through FedEx. Includes parts and labor warranty and free freshenings for 10 years (one a year) for race trannies, along with free inline MagneFine filter and shifter arm bushing. Which year and what horsepower level are you after? Perhaps I can help - let me know.

David
