The SR is famous to youngsters. The SR is decent engine and has some racing life, but it's not established the longevity and history of the L.
The FJ is a formidable engine and had its moment, but it was an incredibly brief one.
The S was similarly potent and a little longer used, but still too rare.
The A was a tough little engine, but a stolen design.
The KA and CA are also rans.
The contenders for fame are the L and the RB with the little SR taking up the rear.
Now as you watch this L lay down 400+hp through carburetors realize that design is over 40 years old and the block and head over 30 years old. When I see a 30 year old SR still kicking a** in 2020 we can talk.
