There are two Speedometer Pro apps. Which one is the correct one?

Never ever use a fusible link in an enclosed area such as behind the dash or if fuel vapors are present. If it blows, there can be fire and sparks for a moment as well as some smoke.

Here is a page from Longacre's web site dealing with bump steer and setup. My apologies if you have already seen it. Longacre Racing Online -- Tech Article "Bump Steer "

The 3/4" master didn't give enough feel to the clutch on my Cobra, it was almost like there was nothing connected to the pedal, so I switched to a 1" to raise the resistance a little. I'm using a Wilwood 7/8" external slave but the feel should be about the same. You defiantly need a clutch...

What list number is the Holley carb? I've never seen one that used a left side fuel inlet. I have the same fuel pump on my Cobra. It's noisy, but the noise seems to be diminishing a little with time. After about 1.5 years the pump started leaking from the bottom plate, a gasket had failed...

Hülsenmutter is a sleeve nut, but I couldn't find them in McMaster-Carr, but they may go under another name there.

Look at Fuel Safe Racing Cells they have the tube type fuel level senders, and may be cheaper than a one off custom design.

The offset bolt hole is so the flywheel can only be installed on the crank shaft one way, so the counterweight is in the correct position.

On the subject of wheel studs, you should have at least 1/2" of thread showing beyond the lug nut, if not you need longer studs. Some of the long aftermarket studs are not up to the task, having a poor thread fit and not made from the best materials. Of all the aftermarket studs, ARP studs are...

I'm going to use the ones in the photo, except with breather tubes welded to the openings. They were standard on early '80 Mustangs, and will clear most roller rockers.

As a point of clarification, the 255 CI was a development of the 302 as an economy engine, and came after the 302. It was basically worthless. Heads had very small ports and valves, and larger heads couldn't be fitted because of the small bore size. It wasn't one of their "better ideas." The...

I always thought the Kellison looked more like a Ferrari Dino than a GT40. The only ones I've seen were bolted to a VW floorpan, but this was many years ago.

If you find you have a problem with radiant heat coming through the aluminum box, use some Thermotek heat barrier on the outside between the box and the header. This stuff is amazing, it comes adhesive backed or plain. John Thermo-Tec: Aluminized Heat Barrier

That's correct, they are a 1.6 for both the intake and exhaust.

Make sure you test fit the pan prior to installing. I had to send mine back to Armando have the mounting bolt holes redrilled. Other than that, it's a great pan, and I also noticed a drop in oil temps after switching to the Armando's pan. Armando can also install a dip stick bung in the side...

You will be time and money ahead if you discard the 2G and replace it with a 3G. The 2G has some known faults, such as the positive charge wire is undersized and the plug has been known to fail. The 3G addresses all the shortcomings of the 2G. They are available in a small case 95 amp model...

Oe of the problems with a wet sump is even with a pan that's properly baffled and has all the scrapers, trap doors etc, is during a sustained high G loading turn or braking event, when using a rear sump pan, the trap door area of the sump can be pumped dry because the oil is held by the G...

Here is the wiring manual for the Painless generic 12 circuit system. You will still need to adapt it to your car but that should be easy enough to accomplish. I much prefer the American Autowire over the Painless harness. The wire in the AAW harness is of a better quality, but the Painless...

Check out Thermo-tec heat barrier. It's very thin, but does an excellent job of blocking heat. I have it on the aluminum foot wells of my Cobra, approximately 1/4" from the exhaust header, and it blocks all heat transfer. Thermo-Tec: Aluminized Heat Barrier
