Gold Yenko at Mecum sets record

Some things to add.
First and second design L-88's are VERY different.
Actually, VERY little is the same between the 2

Assuming this was a first design.
840 heads would be a direct bolt on.
If exhaust seats were slightly enlarged all hard parts from the 842's could be used.
Exhaust valves are not as big as 074's.

This combo would have been closed chamber and 12.5- 1 compression.
This combo would have looked stock and is a huge upgrade.
Cam would have sounded quite different.
If a fair fight [motor wise anyway] was desired this should have been run against a 68 Hemi Dart or Barracuda.
Street Hemis are castrated like a Boss 429 Mustang.
Both are very mild in pure stock form.


Second design L-88's are open chamber and 12- 1 compression.
Never installed in cars [IIRC] and are really a ZL- 1 with a 512 cast block.
