I finally got a weekend day to myself so I replaced the intake/exhaust gasket and 2 of the headder collector gaskets. When I put the 4 barrel on I didnt take the headders completely off so they leaked around the 4th, 5th and 6th exhaust ports. I also got it warmed up and pulled the rocker cover. I found the #6 exhaust to be VERY loose. I adjusted them all though, they were all loose. This engine has never been quieter, even when running the stock exhaust. I used to adjust the valves hot but not running, but never again, it will always be running from now on.
You can actually hear the slight miss of the cam at idle. of course the idle is set kind of low(650rpm in neutral). the headers and turbo muffler sound sweet under throttle.
the primaries seem to be jetted about right but I think I'm going to have to go a couple sizes smaller on the secondaries though. when I let off after hard throttle it will usually pop through the exhaust a couple of times. I hope to get it to the track again in late september so I'll keep you posted.

It's not rocket science, we're just splitting atoms.

Yep, does look nice. What filter holder and filter is that? and what muffler?
rock

the carb is a 465cfm unit.
the airfilter is a K&N, my brother in law gave me the aircleaner housing. it was just lying around in his garage.
the muffler is Cherrybomb turbo muffler. It's not a glass pac.

what exactly is a glass pack?

Basically a tube with louvers, with fiber glass insulation around it. Irritating on long drives.

what are louvers?
and "parallel universe, so much better says alternate you? i have wondered about that for a long time...

OK, do you know what perforated means? Think of a tube with alot of holes in it, surounded by fiber glass insulation. I'll change my sig line to avoid any future confusion. In the mean time, here is a link for your viewing pleasure:http://auto.howstuffworks.com/muffler5.htm

That was a great sig. I told my friend about it and he cracked up, just like I did. Oh well.
