Can i call comp cams ...I got the chance to buy a roller cam and roller rockers for a great price...the guy only knows its close to a .470 lift...he sent me some #s off the camshaft....4714yn,1197,????,3311,3312ehr12?4...what the @.%.#.& I dont have a clue what that means..anyone?will these numbers do anygood to call cc with. thanks

 

3311 & 3312 are the lobe numbers, from their lobe catalog; hr12 is a hyd roller with 112° LSA. That info right there will tell you exactly what it is.

It sounds like one of the smaller HRxxxHR cams, like about a 270. But their lobe library isn't in their catalog any more, so I can't help you get any closer than that.

 

Check out their web site it is there.

 

3311 is the XE258 cam, or 206 duration at .050". .480 lift with 1.5 rocker

3312 is the exhaust lobe XE264... or 212 duration at .050" .488 lift with 1.5 rocker

basically a hotter ramp rate L98 cam

 

If you know where to find it, let us know. Used to be the Table Of Contents in their on-line catalog; "Lobe Master List" or something like that. Not there any more.

 

Go to comp cams main page... on the bottom right of the screen (right above the logos for RHS, ZEX, TCI, etc) there is the master lobe catalog link

 

I love this website ..you guys are awesome thanks.

 

Btw I have that peanut grind cam in a 383 . It is the retro roller version 12-408-8. Installed in a stock 86 z51 vette, tpi stock maf bua untuned. no cats 2-1-2 exhaust, 24# injectors, the (crappy) 170 edelbrock performer Al heads roller rockers.

This set up will lite the tires with just throttle (no power brake) 10ft in 1st, 6 in of sideways barking 2nd, and a loose rear end at 75 mph when it hits 3rd shifting off the gov. runs 125 mph @ 5000 rpm in 3rd. gets 15 city and 20 highway. makes for a nice no lope street machine.

ordered a prominator to start the tune. Its just a grandpa car.
