3/4 cam
most of the guys that i hear refering to cams like that are guys that have family or friends that have raced way back and thats what they grew up knowing. just like pop-up pistons and wrinkle wall slicks. i see the at the track on test and tune or around town on saturday nights crusin'. these guys may not have the best looking cars or the fastest but you know they are very proud of there cars. and they have tons of fun with them. i help them or answer and questions they may ask me, and they appreciate everything you say. i know what there talking about when they call these items what they do and i don't make fun of them or insult them in any way, to hurt there feeling or dampen there spirits. most of them are great guys that would give the shirt off there backs just to help or be a part of your racing world. we all have had to start some where. sorry for rambling on ...jmo.... matt
