I put one in my stroked (3.51) 340. Let me say, I loved it at first, but it is kind of obnoxious.  My Barracuda has TTI headers $ exhaust with 50 series flowmasters. The performance is excellent, but I haven't got any data to give you. Just seat of the pants, and it pulls hard. My brakes are manual disc conversion, so the cam has no effect on them.

whiplash ROLLER cam is even better
I posted over on the truck section about this. I am looking at the thumper cam too. That word 'roller' sounds expensive to me. The videos on the barracuda seem pretty convincing.

if your not starting with a roller block,it can be for a full retro roller cam set up. I started with a roller block and used all stock roller gear,1/2 the price that way. the whiplash is for stock Low CR engines,and street driving. thunder need high CR,stall,gears,intake,carb,headers..ect..ect.. I will be getting me a set of those magnum muffs also the vid lew posted street nasty right there

"whiplash" ...ouch!
I bet the feel is better than sound,and it does sound good
Thanks! Car launches hard with no stall and pulls hard to 5500. My dad (Lew) and I are very happy with it's sound and performance. We have said several times that if for some reason this cam wipes, we would replace it with the exact same cam.
