It's a custom grind solid roller from KC. 248/254 duration, .675/.682 lift with a 110 LSA.
Just curious as to what this thing will sound like when it's idling....thumpy? Rough?

Blynk:
Mine is a KC build. Custom Solid Roller: 262/268 duration @ .050; .651/.670 lift with 110.0 separation which is relatively close to what you are going to be experiencing. Let me put it to you this way; in order to "talk" within 10 feet of the vehicle, you will have to stand in front, or in back of the car. Standing anywhere on the sides of the car requires a Marine Corps D.I. presentation. I am not being facitious one iota. It idles at 1200 in neutral and drops to 800 under load in gear (Race Prepped AOD). If you have a radio in the car; it just became useless. Passenger discussions are no longer in the equation. With a stick; you can idle at 800. The lope is more of a smooth, authoritative "rumble", not that stalling kind of lope and the sound is serious deep. On the downside: throttle response to 7000 is instantaneous coupled with a ton of torque and you can smokem through the first 3 gears. The first time the car breaks loose in 2nd or 3rd gear, you may wet your pants and "fear" will now be an integral part of your driving experience. (BTW: mines a porker at 3200lbs.) That fear had better give you a new found respect for your machine. Remember the word "fear"; it may save your life.
