Grwing up i use to hear "Gearheads "talking about cams then I learn more about cams ,it was more technical it was all about lift and duration. so back in the day ,what was a 3/4 cam? i have one in my 327 at least that is what the guy who sold me the truck claims , if I remember this was the biggest streetable cam ?it sounds radical and it will fly.

Posted by dixie  -  01/25/2008 08:46 PM Thats just an old word for a small cam.well lets see the old duntov sounded real bad then along came the 30-30 an it was badder neither one was a very radical cam can't remember the specs on them someone will. it don't have to sound real bad anymore to work real good,ah the day of modern techo. jim grace [ View ] [ Email ] [ Blogs ] [ Car Ads ] dade city, Florida Charter Member since January 2006   Posted by blade58  -  01/25/2008 08:47 PM So how small?is it bigger then "30/30" cam which came on Z/28 302 in 69 blade58 [ View ] [ Email ] [ Blogs ] [ Car Ads ] apopka, Florida   Posted by dixie  -  01/25/2008 08:55 PM YOU can't say what is is if you don't even know the spec on it, i'm just saying that a slang thats been around longer than me an thats old 3/4 are full race hell you can call it what ever you want don't mean a thing. SORRY O by the way bring that truck to dade city tomorrow big show get there early.if you make it look me up. jim grace [ View ] [ Email ] [ Blogs ] [ Car Ads ] dade city, Florida Charter Member since January 2006   Posted by CK  -  01/25/2008 11:13 PM Yes Dixie is right. Back in the day everyone measured cams at different lifts. Today the standard is .050, all manufactures today use it. But before some used .030,.040,.050 so you couldnt really compare one to another as far as duration and lift. Ken CK [ View ] [ Email ] [ Blogs ] [ Car Ads ] mililani, Hawaii   Posted by tlp1968  -  01/26/2008 01:04 AM The 3/4 cam term is so very general. It usually meant 3/4 race or not full race but close. The 30/30 was a Zora Duntov small block cam that had the valves set at .030- hence the name. It is much more accurate to tell your cam size but as Cris mentioned you can lose folks in the discussion if they don't have the gearhead background.

They were generally referred to as 3/4 or full race cams. I don't remember if they gave a spec sheet with the re-ground cams or not. Papa John [ View ] [ Email ] [ Blogs ] [ Car Ads ] Warrens, Wisconsin   Posted by blade58  -  01/27/2008 01:57 PM Even in the late 70"s the term was still used at least up north where i grew up in OHIO. blade58 [ View ] [ Email ] [ Blogs ] [ Car Ads ] apopka, Florida   Posted by roofcam34  -  01/28/2008 12:38 AM "3/4 race cam" is an old old term back when you didn't have alot of choices in cam grinds. Street/stock, 1/2 race, 3/4 race, full race grind. Technology has changed all that, with all the manufacturers and options available today.
