Yeah, but only if the OP cares about gas mileage. He may just want a DOD cam so he doesn't have to remove the heads. Either way it will give him some insight.

My Avg. fuel is 19.1 and my Avg mph is 33
290-320 total miles before my light comes on, and it takes 15-16 gallons to fill it back up

Geez I missed allot between work and school. I daily my car but my mpg suck anyways since my foot is heavy. My dod is also tuned out. I was unaware that thunder racing had a dod delete kit that cheap. I asked about dod cams from thinking only new era made the only kits and 1200 is a bit out of my budget. I thank you guys for all the info you all bring to me online.

Don't buy the New Era DOD cam and think it will be OK. The cam is degreed in such a way that you'll need to go way over 7000RPM to reach peak power, and your DOD lifters will float long before that.

I think there may be 8 dod lifters and 8 non dod lifters!

Normally, I would never dispute anything you say, but I'm pretty sure that only the intake valves on the DoD cylinders are deactivated, thus the 4 odd-ball lifters.

Yep. The last exhaust charge is trapped to act as a spring and keep tension on the rings.

Ha, thanks... but you know that yours would be too if you wrote it all out. I've got one more pile of parts in the garage to install and then I'm done with the engine, and it'll be time to go back to the track.
