Close. I don't think anyone in the 60s in the US referred to metric displacements. Starting in 1982, Ford began badging their 4942cc Windsor as a "5.0," and the 5 liter Camaro of that era was an actual 5 liter, 305 cid mouse motor. The 302 Z/28 died with the 1960s.

In the 60's it was popular to bore a 283 out to 4 inches. That was called a 301. After the 327 came out in 1962 you could make a 301 by putting a 283 crank in a 327. Then when Chevy started building them in 1967 they called them a 302. With its big bore and short stroke the 301/302 was a great performance engine. The later 305 with smaller bore / longer stroke, not so much.

Buick had a 300 ci V8 in the 60's

Olds built a 307 ci V8 in the 80's

Engineers design the engines, the marketing department decides what to call them. As long as its within an inch or so I don't think it matters much.

Thanks. that's the deal I was talking about and what my friend built for his '61 or '62 Belair coupe. Being kid with part-time job and buying parts paycheck to paycheck he put in a USED Isky cam with the lifters not matched to the lobes they had already been used on. The thing screamed at over 8,000 rpms for a couple of weeks until he wore the cam lobes down

Sorry, my memory of that era isn't as good as some of you others!
