LT1 Front Crank Seal Recommendations

Bought the LME Billet VVT Delete looking to see what everyone is running or recommends for a front seal on a high HP / high boost combination. Running Elite Ultra catch can with their CSS so plenty of venting and vacuum.

Ive seen guys running the ZL1 seals not sure if this is the same as the LT1?
Seen guys running the LS3 seal
Also seen Jannetty Racings LT1 seal.

Just looking for recommendations based on real world use, Thank you...

1000000% spot on!
9K or roadracing mileage on my engine without issue on the seal.
All those miles done in the rpm range of 4k to 7700!

Love my Cam Motion LLR cam!

I'm interested, how much work to install the LS3 seal? What needs to be removed to get access to it?

You basically need to pull the balancer off. Not too hard EXCEPT that MF crank bolt can be a huge pain to break loose and retorque. 240 ft/lbs if i recall. Also I believe its TTY on stock config.

But other than that not too terribly hard.
