with these engines, a cam is very much a suggested mod if you want to get past 300 WHP.
You basically need every other mod but headwork or a cam to hit 300 WHP on the stock cam but you should be able to crack the 12's.
Apparently the stock cam runs out at 350 WHP, but I the club GP dyno list suggests otherwise.
Straight from the list:
Stock Cam:
1. DJ Whiz w/ 317WHP (I/C, stock heads, 1.9 rockers, 8.5:1 CR) [STD]
2. 40thGTP w/ 315WHP (I/C, stock heads, 1.9 rockers)
3. Bronzo23 w/ 303WHP (I/C, stock heads, 1.9 rockers) [SAE]
4. John C w/ 295WHP (non-I/C, stock heads, 1.9 rockers)
5. L67cooled w/ 290WHP (I/C, stock heads)
