Trying to figure out what cam has the more aggressive sound, the Thumpr from Comp or the Hot Rod from FRPP. I have listened to many sound threads on you tube and am thinking that it would be the Thumpr. That must be why the Thumpr requires the Phaser limiters and the hot rods don't. Am I correct in what I am hearing? When I do decide to install cams it will be between these two. Just trying to figure out which one to go with. I want a real aggressive sound but also an HP gain. Between the two, does anyone know which one produces the most HP?

The Thumpers do sound a little more aggressive but the hotrod's are definately not slouches. Something else to consider is that the Thumpers require the phaser limiters which makes them more expensive and reduces mileage. I have seen some dyno's and read a lot of testimonials on these and the consensus seems to be the Thumpers will make a few more HP up top but the hotrods make more power through the whole torque curve. At first I was sold on the Thumpers just because they sounded so good but the added cost and more peaky torque curve have changed my mind about them.

I was the same way. At first I was all about the Hot Rods, then I switched to the Thumprs since they do sound a little more lopey, but the added cost and time having to install limiters made me switch back to Hot Rods. Also, I heard A LOT more people complain about low speed drive-ability issues. Not that the Hot Rods will be perfect like stock, but it seems the Thumprs are worse from what I've read. I also got a killer deal on ebay on some slightly used Hot Rods. I saved about $200. They should be arriving from UPS this week. I'll be installing them on Thanksgiving day.
I'm also thinking of the FRPP ported heads w/ the new style plug in a year or so when the car is paid off. Ford Racing says you'll get over 50 rwhp with the heads and hot rods with stock intake (I have a CAI so it should be better). Sounds good to me!
If you want that classic muscle car sound, the thumpers are for you. I personally love the way they sound. They have the classic lope that everyone loves and are very affordiable. Here are some sound clips.
