Default LN3 and L27 cams any difference?

I have 88 Lesabre T-Type With an LN3 i was wondering if there was any difference between the LN3 and the L27 cams? I would like to get a cam from www.seriesoneperformance.com but some of them say 89-91 or 95.

Steer very far away from SeriesOnePerformance. His customer service cost him his right to be a vendor here, and his prices frankly suck.

Buy that cam directly from Crow Cams in Austrailia if you want it, or have crane or comp grind you one.

Be careful with what year cam you choose as well... The 91 3800 Vin C used the same cam/ set up as the 91 L27..

ok but what is the difference between them? do they have different profiles? what seperates them? If there is no difference then Thats fine i just wanted to know. If i were going aftermarket i would probably go aussie or custom grind buy how shotty Seriesone performance'* website looks. and how its never updated.

Is there a difference between the series one L67 and L27 cams?

There is no difference in the cams. Lobe seperation, lift, and duration are all the same from the 27 to the 67.

Series 2 cams won't work because of the valve stagger.
