Head & cam selection...346 iron w/solid roller or Indy EZ w/XE285HL

Wow, cool comparison. Thanks for posting this.

May I ask how the torque curves compared? I am assuming combo #1 looked just good or better in that RPM range.
Interesting enough, during these tests, #1 averaged 16 lb-ft less between 4,000 and 5,300 rpm. It's not a combination I would choose to run for myself. We just had those parts laying around when we did the test.
