Then your gonna want a cam that will work within the stock spring rates. You can achieve more lope with moving the LSA on the cam from say a 114 to a 112, but this will also shift the power range of the cam. You can have a nice idle sound with a 114 LSA cam with the right exhaust & tune. The lower the idle is set in the PCM the more you'll hear the lope at idle as well.
For instance, I run a 224/224 .581/.581 114 cam in my 99' TA. Its got a ton of useable power, its doesnt lope like a Pro stock car but you can definetly tell its not stock. Its easy on my valve train since I tossed a set of Patriot Gold dual springs rated at over .600" lift.
Always keep in mind, if you put alot of miles on you want a cam thats not gonna be close to max spring rates. You'll go through springs a few sets a year. Again, for example, I have put 60K+ miles on my Patriot springs b/c the lift on my cam is well below the spring max lift rating. So I got more life from my springs. Now there is a point where you can have too much spring but I dont think your gonna worry about that with what it sounds like your wanting to do. Also keep in mind your stock stall converter, you dont want to over-cam it.
Id just get a mild off the shelf cam & set of Comp 918 springs & call it good. Dont forget all the gaskets, new bolts (if any stockers are TTY) for the swap either. Sometimes the nickle & dime stuff will eat you up if you dont account for it.
