Don't kill me. Another 5.3 cam question

Don't kill me. Another 5.3 cam question
Emailed cam motion, no reply, I need a cam quick.
setup:
Forged 5.3, wiseco pistons, scat rods, 317 heads,
compression with 317s will be 8.5:1 but I'm most likely going to swap over to 243s to bring it into the 9.5 :1 cr. Going in a 4400lb+ 78 transam. Going through a t56 magnum.
looking to keep it around 700hp using pump gas
thinking about going with a genuine s475
still want this thing to sound gnarley, I LOVE the sound of N/A Lopey cams. I don't mind having someone spec me a cam or just buying an off shelf cam.
thanks for any suggestions

" Why not do it right the first time" ??? Wouldn't that include the heads you want? A point of compression is a big difference when your talking lower compression numbers like those and cam selection. How are the upper rpms on the cam with 103 CL? Seems like a weird combination of CL and .050 duration. The worst thing you can do is have a mismatched combo between heads, compression, cam etc. it won't run nearly as well as a nicely out together combo.

Stage 3 ljms cam is way to big for your goals. The stage 2 has made over a 1000 whp and still has the sound you are after. They are right a full point of compression is going to be a huge difference on the street.

All of the recommendations in this thread are spot on. I personally would go with the Jegs 228/230 cam. Very good budget choice. Otherwise an LJMS Stage 2 would be my choice.

228/233 on a 111+4
Same intake open and exhaust close as the shelf stage 2.... more overlap to help get the turbine wheel excited since you do not have a torque converter to spool against.

I must be misreading this. Same intake open and exhaust close, yet more overlap??? Confused.
