cam battle

I have a 383 ls6 with all bolt ons lpe 243's 2.02/1.57 and a 281 hr high rpm street cam
2200-7200rpm
0.006 valve timing
112 lobe
intake 110
valve lash hyd exaust
duration 281 283
duration at .050" 228 230
valve lift 0.571 0.573
lobe lift 0.336 0.337
valve timing at 0.006" lift

This cam was on my original 346ci engine. I have been looking into cams that match my heads and ci. Most say go the ms3 and ms4 route. How would a compcam xtreme xe r
xer287hr 238/240.605/.609 with 1.7 rockers. 112lsa 2800-7200 be. More livable than ms3 and ms4? power comparison?
Reason i ask is super chevy did an ls383 carb special with 205 afr's. 560hp 505 torque with the hr287. A fellow on here said his engine builder told him that his would make the same numbers. His had a ms4 cam,fuel injection, and 205 afrs i believe

I like the comp cam better because it will be easier on springs. the LSK intake lobe on a MS4 is tough on springs.

I know its alittle big for my 346, but I went with Trickflow's 238/242 .595/.595 112lsa....rated at 3,000-7,000 for the 346 so the rpm range should drop alittle for the 383........ you should take a look at itm
plus its under .600" lift so your valve springs will thank you

Get patrick G to spec you out a custom cam, I guarantee it will be the best $20 you will spend on your motor.
