Driven;
Since you asked. Were I stopped this thread last, I had a few more issures with oil leaks and carb running rich that i didnt bother posting. To be honest I had run out of steam, and didnt feel like dealing with even the basic tuning stuff. So i just put it away for the winter, and will deal with it this spring.
The short list of TO DO's;
1) Rebuild Carb and test it on an engine prior to spring.
2) Install Cork Valve Cover Gaskets
3) Install new starter, and possibly new flexplate.
4) Possibly looking at getting a Vacuum Pump. GZ motorsports is looking good.
If you look at the video on the previous page, you will notice the car blows out two giant black plumes of pig rich smoke when revving. This is the carburetor issue. Brand new out of the box Demon 850 (BG model). It ran "fine" but very rich on the stand during break in. Once installed in the car, and the idle set correctly with the transfer slots correct, i could not get it to idle. The boosters were pouring fuel in like it was at WOT, and the engine would just flood out. The immediate response from everyone was FUEL PRESSURE! For as long as I have been into cars, I thought 7psi was the hot ticket, even though the performance car Carter pumps only put out abut 3.5psi. I measured 6psi in my system at 2 different places with 2 gauges. System is a Holley Black electric pump, with aeromotive regulator (Return Style), with 1/2" fuel lines everywhere. I also tried taking the carb apart and cleaning out the passages with compressed air, to no avail. Plan is to rebuild the carb, test it on my corvette or a buddy's Olds 455, and if it works try it on my car. If it still floods, then I'll crank down the fueel pressure till it stops.
For the moment I stuck the old Edelbrock 650 back on. Its not enough carb.
Also after the stopped, I had numerous oil leaks. Basicaly what I fixed in the last page didnt work. Its like the rear oil pan gasket keeps pushing out because of the oil pan. Good news is, if the car is warmed up, the leak will stop after a while. I also had the intake manifold leaking, and dripping/burning on the headers. My RTV bead had pushed out. So I had to reseal it. This time i used RIGHT STUFF, and holy crap! I cant beleive I never tried this stuff before. It works great.
I also had the valve cover gaskets pop out. So I glued with RTV one side to the block. They held for a bit, but pushed out after a while on my maiden voyage. Going to switch these out for cork. The cork weeps a bit, but I like that they "swell" when oil soaked, which helps to reseal them after heat cycles. Finally all of my Oil PSI fittings had to be resealed. Which was a harder task than it sounds.
The starter and flexplate issue has been a challenge from day 1.
My Powermaster 9600 starter which was supposed to fit perfect right out of the box had awful clearance, and the instructions were garbage.
Most starters you need to shim, but this one was too far from the ring gear. I ended up having to mill off .075" from the mounting block (opposite of shimming) to get proper clearance. It seemed to do the trick. But I had chewed up my SFI flexplate pretty good by this point.
It worked for a while, but now the starter wont engage. The new process for starting the car starts with crawling underneath to enagage the starter and flexplate by hand lol. I have a new starter and flexplate, just need to put them in. This starter is OK, but I dont want to deal with it not working again, so its goin on the shelf for a while.

Other than that, like I said, its in storage for now. The maiden voyage drive was amazing. it would roast the tires in any gear at any speed. Its a bit mind boggling how quickly this thing revs! Love it.
Here is a pic of the car immediately after its maiden voyage.
