COOL!  It's posts like this that keep me coming back, I would not have ever thought using the waste heat from cooling system could reduce drag or potentially give some amount of thrust.

Look in to the amount of thrust and downforce that zoomie headers on Top Fuel cars can generate. There's some serious forces going on there!

Its the same with the exhaust on a for example a P51 and other planes there is a reason why they are shaped like they are. They give quite a bit of thrust

Everything is done and ready to run on the dyno, except that I am STILL waiting for valve springs from PAC  >:(  They were supposed to ship Monday, but I haven't received them yet...

Thanks for the update. I've waited months for interior parts for the Cougar. Gave me extra time to research and refine other aspects of the restoration. Guess you've been staging as much as possible during the wait.

My rather ambitious goal was to run some ported Edelbrock heads with a good single 4 intake and a tunnel ram, then same with a set of CNC  ported Blue Thunder medium riser heads, then run both pairs of my heads (Stock Exhaust and Raised Exhaust) with all three cast intake options (4V, 8V, and crossram).  I'd like to have all that comparison data, and I'll get it all eventually, but right now I'd kill for the damned valve springs and just run one set of my heads to see what they do.  It has been ridiculous waiting for the valvesprings to arrive...

Yes, at this point I believe that the casting issues have been resolved.  I've had 6 or 7 good head castings in a row now, so no issues there...

Is there something extremely specific to those valve springs, so that a similar set from someone else won't work? Lots of spring suppliers out there

If I didn’t have a job that takes up most of my free time I would volunteer to be a garage monkey to help swap heads intakes ,run for cool drinks, etc...I would only ask for a dry place to sleep.

I only go with Comp and PAC for springs, haven't tried the others, and I really don't want to experiment with a new supplier on this setup.  Comp has a triple spring that will work, but then I'd need new retainers to go with them, and I've already got the PAC retainers.  Plus, the PAC springs I've selected are dual springs, which will be lighter and work better at high engine speeds.  So I've decided to wait for the PAC springs.  Hopefully soon...

I felt a great disturbance in the force, like thousands of voices cried out at the same time...

“ deliver the damn springs already....”

Jay has plenty of help waiting, if he needs it. Most of the stuff is a one man job, and Jay does the work of 2 guys. LOL.

Would be really cool if someone could be there just video-ing the testing and such, would make for some great YouTube videos.

I have to agree with this. I would love to watch it.
