My Cam Card says:

Intake Valve Lift - .64627
Exhaust Valve Lift - .62974

Roller Cams. Weiand 177 blowers

I am running that V6 module. I am not a very knowledgeable person, but several people on here recommended I run it. I worked with Bob M for all my stuff and I "believe" I recall him saying he'd try it as well. In a conversation with Nickerson on my carbs they casually mentioned that with my set-up they would use that V6 module. All of those factors was enough validation for me to spend the 250 bucks and try it.

I am not running ragged edge timing though - I believe I set them up at 32*

All roller and 177 blowers.

I picked up two v6 modules on ebay. I get about 7 deg of total advance. I'm currently running 25 initial with 32 total.
