Does anyone have an actual CAM CARD for GM's LT4 HOT cam??
I know the specs @ .050 lift 218 228, .525 lift with 1.6, .492 with 1.5 rockers. I would like a cam card to help me better degree in the cam for my friends buildup. I need IVO, IVC, EVO, EVC events. Thanks!

not a cam card. but according to DD2000 the LT4 hot cam numbers are as follows:
IVO = 0.3
IVC = 38.8
EVO = 49.1
EVC = -0.2
hope this helps.

What intake centerline did you use when you entered those specs? I know the lobe sep is 112 but what's the darn centerline #?

It's probably ground with 108* ICA since most small block Chevys operate best with 4*, but that doesn't matter. You can make it whatever you want.
The specs mrr23 gave put it at 109.3* ATDC if that helps.

I'm bringing this back up.
I've been searching the web for over 30 minutes and it seems nobody has a cam card for the LT4 hot cam.
If anyone has the car info or has degreed the cam themselves please post the specs from the card!
Thank you.

The Lunati 50143 is very similar to the LT4 Hot Cam. I would venture to say it is identical for all intents and purposes.
219 / 227 (@ .05" lift)
.471" / .480" (1.5 rocker ratio)
IVO - 1.5*
IVC - 37.5*
EVO - 49.5*
EVC - -2.5*
Centerline - 108*
Lobe Separation - 112*

It's a better choice for Vortec heads.
