“The 1970 Vista Cruiser could be ordered with a 455 V8 monster of an engine”
“The Nomad was a popular model designed for small business owners and families, but with the addition of a 283 HP engine, it was fast and could outperform some sports cars of the day.”
“For 1966 and 1967, Ford offered 428 V8 engines as an option on its station wagon model lineup. The 428 V8 in question was not the famed Cobra Jet, but the engine from the Thunderbird with 345 underrated horsepower. With over 460 lb-ft of torque, the Country Squire could really go despite its size and weight.”
