Question Help me decide, 327 build or swap in a 383le2 lt1 (67rs) ---

I decided that I dont want to keep my 96z28 anymore....so when I sell it the money will go into my 67'rs build.

I am not sure what direction I want to head now. I have thousands of dollars in parts for my lt1 that I luckily didnt install yet. My main goal is 500rwhp , a roots supercharger whine, and an idle like this (lt1) 383 le2:

actually that is the exact setup I have purchased already (lt1) 383 le2:





I like the reliability of the lt1 too, but I dont think I can swap a roots supercharger on it without a TON of custom work and tuning problems. That cam is a low lsa , so the overlap and boost worries me. I have a 125 shot, but hate the idea of nitrous.

***Right now for the 67'rs I have a weiand 142 blower, AFR eliminator heads, eagle h rods, 1.6 roller rockers, hooker headers, the stock small journal forged crank, and a b&m superjection fuel injection modded for 500rwhp. I am just totally stuck on a good cam to get the sound I want above, and am not sure how reliable/streetable it will be. Naturally aspirated cams always sound meaner than supercharged ones in my experience from the lsa.

Any opinions/advice/help is appreciated. I am stuck on which way to go and would like to start selling parts for the future build.

Main goal is 500rwhp, supercharger whine, reliability (relatively), and a lopey cam. Everything is up in the air. Thanks ---

So, if I decided to go the custom cam route on the 67' is it worth it for the machine work to make it a roller cam engine? I think thats why I like the sound of the lt1 so much, the roller cams have better streetable "big" cams ---
