I am about to build up the engine in my 84 Camaro anyone have experience with the Comp Cams "***** Thumpr" cam????? I have been watching a lot of you-tube video's and those cam's sound great just wondering how they performed??? and yes I know the heads are being changed cast iron so far (Wife will be driving this vehicle so I have to keep it simple) any ways, I figured Cam, heads, and roller rockers still doing math on what ratio rocker I will use. I would build the motor entirely but I have (Project Nightmare) under construction. (for last 3.5 years) so 95% of time and money go into that one.... anyways if someone has actual real world experience with the ***** thumpr cams I would appreciate real input.

 

If you want any valuable guidance on cams, you probably don't want to solicit those who are familiar with ***** Thumpr cams. They are a marketing gimmick to appeal to and sell cams to people who don't understand them.
They're not something "bad". The cams themselves are nothing new. You can pick one up, check its specs and find that the same cam has been used by somebody somewhere for decades.
Don't expect a cam to sound badass AND perform to the vehicle's potential in most street applications.
The way to approach this is: decide what the goals for the car are, consider its weight, gearing, rpm capability of the rest of the engine - heads, valvetrain, bottom end, your tolerance for a higher stall torque converter, its typical use -tearing around on weekends, track use, daily driver? ........ then you'll have some guidelines and boundaries for choosing a cam. If you're staying flat tappet in that engine, stay on the mild side with ramp rates, lift, and spring pressure.

 

That's a poser cam sounds like but isn't.
