Two things to keep in mind here with Tedd's information he offered here.
This 1964 10.5:1 compression special edition 394 he's talking about was 345 GROSS hp rated.
When talking about a modern engine against a Vintage pre-1972 engine, the HP rated values are not
You have to put both engines into the same measurement system to get an accurate perception to compare them.
I'd say a very large % of hot rodders don't do this.
GROSS VS NET HP RATINGS
345hp in the Gross rated
system is more like 280-290hp in today's SAE/net hp system that's been in use for 40 years now.
So to make things a fair comparison, using the
394ci 6.5L big block = 280hp
VS 327ci 5.3L LS small block = 315hp
394ci 6.5L big block = 345hp
VS 327ci 5.3L LS small block = 375-385hp.
Todays' hot performance Pony Cars (Camaro SS, Shelby GT500,) are all about 4000lbs.
