L78 Horsepower..
When the L78 was introduced in 1965 it was rated at 425hp...this was based on 6400 rpm's...almost 1,000 rpm lower than the engine being discussed. Most folks would agree that the later 375hp rating was low...headers, properly tuned distributor/carb and blueprinted assembly all make a huge difference.
Last one we did was a 70 402 version...pancake intake, Eric prepared 4492 and run thru headers...it made north of 430hp. Again, the real power difference in these motors is in the details. -wilma
