History To some, the Chevrolet 454 big block was the right engine at the wrong time. Building on the popularity of its 427-cubic-inch engine, General Motors introduced the 454 in 1970—one year before emissions standards were tightened and just three years before the gas crisis hit with full force.
What kind of transmission did a 1970 Chevelle 454 have?
Transmissions: The standard transmission on the 1970 SS 454 was the Muncie M21 close-ratio 4-speed manual with an 11-inch clutch. For 1971 and 1972, the stock 4-speed was replaced with the heavy-duty M22 unit. The M40 three-speed Turbo Hydra-Matic was optional with both engines in 1970 and ’71, and with the sole remaining 454 in 1972.

How big of a fan do I need for a 500 hp Chevelle?
If you’re producing up to 500 hp, an electric fan rated at 2,500 cubic feet per minute (cfm) of airflow with a full shroud is generally sufficient to keep it cool. Above 500, you want a fan that can pull at least 3,000 cfm.
Where does the air go in a Chevelle cooling system?
Air always takes the path of least resistance, and, without a fan shroud to force the air to be drawn through the radiator, it goes above and below the radiator instead. If you have most of the fan shroud in place, but are missing a section or have a broken shroud, most of the air is pulled in through this section.
