I’m not going to rattle can my new stroker block.  So I need a color code off something. 
 

The alternator bracket seemed like the best choice for still have original paint and be something I can easily take off. I found another that was plated to replace it. This is the last grimy thing on my original motor. 
 

 I will have a ppg shop scan it next week. It’s darker blue then I would have guessed.

ITB with IAC and pcv here I come. 

Which mount looks better. Stock coil mount or the rubber one? Rubber one looks lower profile.

First one, looks more appropriate and fitting in with the aesthetic of the car.

I got pretty far on the intake. I figured out my basic plan. I also tig welded the old holes and drilled and tapped new ones. So they are centered better. 
 

I tapped all existing holes for npt plugs. I also drilled each runner to 9mm. I bought a bspt 1/4 for the stock pcv fitting. Also a 5/8 hose Barb by 3/8 npt brass for the iac. 
 

I also had my stacks turned down to fit some cheap filters. Brass or no brass?

My decision on iac location.  I can use the stock 12v + from the coil and also the coil negative wiring for the iac connected to my haltech. So wiring will stay the same.
