Alright....this winter when I pull the 409 out of the impala, I plan on changing the cam, valve springs, and a new timing chain/gear setup. What I'm looking for is I want the car to sound like it's hungry. I want the thing to cackle and grab attention. The car will have either a 4.10 or a 4.56 gear, it's a close ratio super t10 4 speed as well. Basically I want the car to sound as bitchin as it looks. Not looking for an all out racecar, as I already have one of those. Just a nasty sounding street cruiser with the occasional blast through the gears. Was thinking of a solid roller that way I don't have to worry about cam break in. But if I end up with a regular solid lifter cam that's fine too. Don't get me wrong, the car sounds good for what it is. But it's missing that cackle at idle. That cackle that makes people turn their heads, that cackle that you can hear tick in the 2 inch fenderwell headers. Thanks!
