Attn: 383 should I switch cams?
The current cam can be found here. Its the second Nitrous HP cam(in the blue part)
http://www.compcams.com/catalog/064_065.html
My current setup is as follows.
383 stroker
TFS twisted wedge heads 10.5:1 compression
1.5:1 aluminium roller rockers
TRW forged flat top pistons.
hydralic flat tappet cam as shown in above link
670TBI with 85# injectors for now.
intake is undecided. Probably performer RPM or a Weiand.
This cam was orginally ran with a blower and I feel that these heads are made to breath and this cam is costing ~40HP. Is it worth it to go ahead and switch cams out? Which one?
I was thinking something in the 224/234 @.500/.500 112-114lsa
I really don't want to push it to 510 lift. Also would 114 LSA cost me much power. Trying to be streetable.

The next cam on the list would probably work great in your 383 too. Engines with more cubic inches can take more lift than those with less cubic inches. If it is worth changing the cams out depends on how hard or easy it is for you, how much you'd enjoy doing that, and if you wouldn't mind more of a lumpy cam.
The 114 LSA would work better for a blown or juiced engine. The longer LSA also broadens the powerband, smooths out the idle, and gets slightly better emissions, so it'd be more streetable.
