You are right though Lilhemi, I guess these pics on this thread are kinda old, I should post some of the new ones.

Yeeeeah dude that things friggin' rad! How hard was the bridge port? I'm gearing up to do one myself. Did you have it done or did you do it your self? And what is the goo on the rotor? Is that engine asembly lube or something to hold the seals in place during assembly? Love the vid! Brap brap is right! That seemed to be at a pretty low idle.
I have heard the same thing about fram filters. A couple of buddies have had their oil pressure run high with them too. I think that Hastings, Bosch or Purilator are better. Oh and you know Mobile 1 is good, if not a bit expensive.
On the subject of the holley, I remember seeing that nitrous adapter at work and thinking how cool it was that it would bolt right onto my car. The holley is a bit easier to tune when you're running nitrous too. A Weber only has 2 fuel circuits (idle and main). A Holley has 3 since there is a power valve. That really helps with tuning when you're making power like a bridge ported nitrous injected 13b will. If you were auto x ing then it might be different but for drak its sweet.

I bought the engine from a road race guy and it was already bridge ported. I tried the nitrous on the carbon seals the engine came with, and they only lasted about 5 passes on a 100 shot. So I tore it down and used Atkins seals. The yellow "goo" isnt actually goo. Its a coating on the rotor. Not sure what it is, since I didnt put it there.
The idle in the vid was about 1200. With the Holley, I have to idle the engine at about 1650. This is so the engine doesnt labor at night when the alternator is under load from the lights being on.
The nitrous plate kit is for any holley, just a simple little kit for any Holley flange. Only two jets to change. Just make sure you port a plenum into your manifold first so the nitrous doesnt spray against the flat surface of the RB manifold and puddle up.
A holley has 4 circuits if your gonna count the power valve. An idle circuit, a transfer circuit (from going from the idle to the mains) and a main circuit. It also has all these circuits for the primary throttle blades, and the secondaries. You basically tune the primaries for driving around on so it drives good, and tune the rest of the WOT in with the secondaries. It also has nice big accelerator pumps, something the Weber lacks (they are small).
By the way, even the Weber IDA carbs have 3 circuits as well, although the transfer slot doesnt work very well on a high overlap engine like a bridgy.

Here is a pic of the narrowed Ford 9 inch I put in the car. It has a spool with 5.14 gears and 31 spline axles. I modified some camero slapper bars to help with the traction with leaf springs. I had the axles use a Ford 5 lug pattern so I could use Weld draglites, and then I had to buy a brake kit that changed the front hubs to a Ford 5 lug pattern so I could put matching rims on the front. The car also has a 3 inch electric cutout for racing, because I have to run two mufflers to keep the noise down when driving her on the street.

Here is a pic of the super fancy front brake kit I got from Tony at TheRacingStore.com . Super nice stuff. Just bolted right on. Made it super easy to put the front wheels on, and it has more than enough stopping power now.

Just a quick note about the carbs. The RB-modded dellorto has 5 staggered holes for the progression circuit, and isn't matched by anything else out there for daily driving. Between the great progression, fuel-enrich choke (rather than trying to cut the air intake) and hot-swappable jets (while it's running), it really can't be matched. That said, I prefer the Weber, as I like the design and the progression can be improved by anyone with a good drill index. It's nothing but a couple of holes, after all.

I probably wont paint it for a couple years. Right now I am just sorting out the combo. I am just waiting for winter to pass so I can go to the track and get some times.

Rotaries hate me. I've had trouble with the damn nitrous system on this car all year long. I finally changed this from a plate kit to a direct port. We'll see what happens.
