Any more updates?

I apologize for being slow with my updates, but I have made progress!!

The new fuel system is installed, 10AN supply/8AN return. I cleaned up the engine compartment, including a new radiator and fan setup (with custom radiator holder). I also had a new tank built with a sump and the proper fuel fittings. Everything seems to be working fairly well, although I'm still trying to get the carb, FPR and BOV dialed in. It's running to rich. I've lowered the pressure on the regulator to 5-5.5 psi, but I think the problem is with the BOV not opening enough at low idle. Any suggestions? I know I need a wideband to help with the tuning, but I want to replace the headers first before installing one. Here's some pictures to catch me/you up,

Looking good.

Where do you have the reference line for the BOV running to?

Is the pump sitting higher then the tank?

Looking good.

It's connected to the back of the carb, same place as the tranny modulator valve. Pump is below the tank. I think my problems is the adjustment on the BOV. Any ideas where to start?

Can't believe it's been almost a year since I've updated this thread!!!! Enjoy.

Not yet. I'm going to get it dyno tuned in a couple of weeks and then I'll play....

New headers, new exhaust, and electric cutouts,

Sounds great!

Tell me about those stainless headers. What brand? Do they hang below the frame?

Here's a thread that tells all about them:

Thanks for the reply. I've been keeping an eye on that thread for a while now.

How do you like the electric cutouts? Any issues with them? What brand did you go with? I ask all of these questions because I plan on doing the exact same exhaust setup as you except I will probably go just a little quieter on the mufflers.

Thanks.

Sounds good and I like the SS headers. I like the muffled exhaust better, just sounds cleaner.

Two things I noticed, your track bar is way off, should be parallel with the ground at ride height. Is your driveshaft too short? I see a lot of the slip yoke in the one picture.

The 50 series flowmasters quieted everything down but it still has a good rumble. The cut outs are just to mess with 5.0's and rice burners,

.

I had to move the mounting point down on the track bar (more pics in my build thread) because it was interferring with the aluminum rearend cover. It seems to work well at this location. I'm replacing the 4" drop springs with 6" drop springs so that should help level it out some.

As far as the driveshaft, it has approximately 2" that go into the transmission, I assume that is enough? I've got a couple more things that I'm going to do to the suspension that could affect that measurement, when I'm done with that I'll verify that everything is still good.

Wild83C10 · 05-01-2011, 09:44 PM

You should have about an inch left out of the trans, so that could be around 3" in the transmission.

Rob,
Did you ever do methanol injection? I believe Steve at NewEra Racing engines does this in lieu of an intercooler to reduce detonation. And in turn, run more boost to make huge power. Sorry if it is in the thread somewhere and I missed it, kinda just skimmed through, instead of reading.

Gorgeous build. Ever take it down the track? (sorry if you posted it and i missed it)

**Hart_Rod** · 11-05-2012, 08:44 PM
