Crane Cams continuously improves and upgrades its cam designs. In some cases this may mean that two Crane Cams with the same part number may actually be different grinds. You must check the GRIND NUMBER stamped on the front of the camshaft and check it against the Grind Number near the top of the Spec Card. For more information on the finest available camshafts, valve train components, and automotive ignition products, visit your local Crane dealer or call the Crane Cams tech line at (386) 258-6174 or FAX (386) 258-6167

Looks like a very mild cam with very lazy ramp rates.

It's not going to be a screamer by any stretch of the imagination, but you'll feel the extra power without a doubt.

what kinda of numbers will this make maybe ? abround 360 - 385 rwh and would 1.8 rr help me any? i mean i couldnt pass this up with all the things listed in my sig , got it all for 300 bucks and hell the programmers is like 450 by its self so i came out alright id just like to know what kinda numbers i may be lookin at and if 1.8 rockers woud help....if my math is right with 1.8rr this would make is a 220/220 . 583/583 with 112 lsa right? would ls8 springs hadlel that


would this cam be better then the hotcam?

Greed4Speed

Thats because when crane started selling LS1 cams they were already 5 years behind in lobe and grind technology for the engine.

Ya, 1.8 rockers will help some if your springs will take the added lift, but for the $400+ you'll spend on them you might as well get a cam that has more lift and duration ground in it.

For a reference search on the MTI C1 "Hammer Cam." Pretty much the same grind, just the C1 was a Comp grind back in the early days.

ill just get the springs my all my buddys nave this stuff laying around , which is how i got it all cheap , but ill do the springs and since the springs will hold up a while ill update the cam later, after all the other things thats on my list to do ....but what kinda power am i lookin at whith the mods that are in my sig?

Kraest

LS6 springs won't even handle the lift that the cam comes with on 1.7:1 rockers.

I definitely wouldn't use those if you plan on upping the lift via rockers.

On a side note, I have a cam, springs, retainers for sale in the for sale section that will blow that cam away for $300.
