I was wondering if anyone has some knowledge to share or links to any sites or articles on these cars? I've watched some great vides on Youtube, it's been particularly interesting to note the suspension and chassis modifications of the era. I'd like to know about the early SOHC engines such as the Tomei built units and also the evolution of the DOHC heads on the A and L series. I'm a Mazda man but but anything high reving and naturally aspirated get's my vote!
