I've seen tests that suggest CF and other composite pushrods really aren't good, as they flex way too much, coupled with the leverage of the rocker arm on the pushrod, removing weight there isn't really worth much compared to a lighter spring/retainer/lock and valve. ------------------

Heads are still at the machine shop but the intake went from mathematical model drawings to reality. Sneak peak of the actual manifold. "Meet The Fogger"!

I don't want to derail your new thread, so consider this a request for a Side Project. If you think you can take on this challenge please start a new Thread in TD&Q.
Supernatural 3.4L 250WHP that will pass California Smog Visual Inspection, etc. How's that for an impossible dream?

Looks like a scale model mock up of a fancy new downtown high-rise project.

I'm pretty sure I can come up with something if I get all the details on how they do yearly inspections. It might take some time but everything is possible if you put your mind to it. But the easy way is turbo charging like everybody else.
How do they conduct the inspetions on your Fiero? What's the procedure?

Got the fuel rails finished today. It looks "Trecky" with the rails on.  I like Star Treck!

Excellent, thank you for thinking about this. Smog check in the PRC ... someone else will chime in who actually KNOWS the complete picture but I can start with the basics:
1) Smog tech does visual inspection. A turbo would be an immediate fail, as would headers or a different intake or changing to DIS. They are also supposed to look at the Sticker that shows the emission system layout and confirm it has not been altered (e.g. digital EGR wouldn't have the expected vacuum hook up.)
2) They jumper the OBD1 connection and check for codes (I think), which rules out using the better 7730 ECM. Link below explains the digital EGR needed for the 7730 would also likely fail at the visual inspection stage.
3) They then run the engine at 2 different speeds with the sniffer in the exhaust pipe. I believe the speeds are Idle (not to exceed 1100 rpm) and 2500 rpm.
Is the 7730 ECM swap CARB legal?

Are you planning on dividing the runners inside the box or just leaving that as one big plenum space?
