[QUOTE="olaosunt, post: 13689933, member: 131643"] I had those cams put in when I bought Joe cofeeman's alluminator for my swap last spring.He had already ported the heads and had a valve work done but the car sounded quite different after the swap;kind of rougher and louder. I am not sure if there were any gains from the cams alone but my low compression alluminator recently made 720 rwhp,620 ft/lb.of torque at 15 psi with E85.The belt was slipping and then broke after the first and only pull. This was with a 69 mm pulley,JLT CAI and elbow and port matched TVS. (going to a 2.9/10 rib set up) In the summer on the same dyno it made about 690 rwhp at 17psi on pump gas. On brenspeed's dyno in the spring it made 704 rwhp and about 600 ft/lbs of torque on 100 octane before the elbow. [/QUOTE]
