thank dude that good info i have a spare doorman here and a hv3 . i may do the same whit my doorman and compare it whit my hv3 at the track whit stock time whit hv3 and whit mod doorman

Wilren, when I get a chance I will pull the plugs and take some pics. I did pull all 3 front ones out and they were all a nice tan color. So, I can only presume that the rears are the same. I have stock AC Delcos in it right now and was thinking of dropping to a colder plug anyway. Just need to get the time to do it. I may just do that when I put the ER rockers in. But so far, I have not had ANY issues with my modded intake. The motor runs real strong and smooth and pulls like a b!tch for a N/A. Just ask Crash or Darrel

Were your cuts pretty exact, or did you just wing it? Do you have the measurements?

Just kind winged it. It took it from edge to edge and in a square. About 1.5" square.

did you ever pull the plugs?
i'm anxious!

Not the backs yet. The front ones I pulled a few weeks back and they were all nice and tan. About perfect.

I'm watching this with interest. What gave you the idea to do that?

I was waiting for the block and crank to come back fromt he machine shop and started tinkering with what I had. Ported the heads and intake and decided to mess with the runners. Figured if it didnt work, I would just get some new runners. I have been pleased with the results. I have a junk UIM and LIM that I plan to use for mockup on my own HV3 style runner. Cant see paying the $100+ for something I can make.

would love to see some clear pics on this not 100% sure on what you did still but sounds like a great mod vs the 200+ for the hv3
