Cam or Heads???

[B1 596]

beyond an alternate firing order cam apparently being the way to go to save crank failures. I'm wondering if anyone has any real life experiences with just a cam swap or just going from stock heads to ported heads with no other changes. Has anyone swapped just a cam in? Or just ported heads? Curious what your experience was over the original stock cam or stock heads? Faster spool? Better egt's? Hp gain? Obviously results will vary with different cam designs but i'd like to hear opinions from those that have done it.

I will be able to answer just a cam swap soon. I had a 8410 regular firing order and switched to a 9100 alternative firing order. They are similar in lifts but the 9100 has about 10 degrees more duration.

Hell I bit the bullet and am doing both now so my build will be showing both.

Got everything back from the machine shop. I'm building it back up now. I took a bunch of work to get it balanced though. I can't wait to get it going.

Got it back to long block status. The valves are lashed and i'm ready to install the injectors and turbo. What numbers do you think i'll make. I'm thinking 740/1300.

Should do that no problem. I can't remember for certain but I think Mark made well over 800 with that turbo?
