Never done wireless start on a hot rod, and not sure why anyone would want to? It's a toy, and I can't think of a time I'd want to start it and not be sitting in the seat watching the gauges?

As for the difference in collectors for Lemons headers. My guess would be they changed to accommodate a request for optimum ground clearance. Possibly the extra .5" diameter had issues hanging too low and getting hit. Might call them and ask why they went to a 3" from earlier 3.5" My old Doug Thorley headers on my '71 with 427 BBC were also 2" primaries, but 3" collectors. My new Doug Thorleys on the Falcon's BBC are 3.5", so it seems they went both ways too.

 

Good tips you mentioned the gauges. This has been a question that I totally forgot about it. What gauges are required for this engine. I would think of:-

Engine oil Temperature
Engine oil Pressure
Engine water Temperature
Engine water Pressure
Battery Voltage
Alternator Charge Current
Fuel Pressure (I do not know if on a carburetted engine it needs an electrical fuel pump)

Any other suitable options?

Thanks

 

Not sure you'd find water pressure, but if you could I wouldn't buy it. Amp meter to measure charge is also not necessary, and even dangerous. I haven't used an amp gauge since the 70's.

I use:
oil pressure
water temperature
voltage
fuel level
speedo
tach-I don't mount a tach in my gauge cluster-separate.

Additional gauges that I have used on cars, but not necessarily in the dash are:

vacuum gauge- I have mine mounted either on the firewall, or in a port on the intake. I only use this for tuning, not constant observation.

fuel pressure- Another gauge that I don't put inside the car. Dangerous to have fuel line going into the interior, and remote wired fuel pressure gauges are way to spendy. I mount mine directly to my fuel pressure regulator and use it to initially set pressure to the carbs. After that I rarely look at it.

Some people go nuts with gauges, because they think it looks cool. My attitude is if I rarely look at it, I don't want it in my dash.
This is the gauge cluster on my BBC powered Falcon:

 

Thanks for your opinion. I agree with you with your last statement.

Why a vacuum gauge is important and needed for tuning? What do you tune/adjust?

 

Woooo! Be sure to post up pics of your connecting rod stew! Grab a cold beverage and google tuning with a vacuum gauge. Read multiple ways. The gauge can tell you so much about the condition of your engine its unreal. From weak valve springs to bad rings. It can all be determined with a simple $10 vac gauge.

Val, thanks for the info on the cutouts, the spring loaded motor is nice.

Moroso sells what is basically a diaphragm with a npt port on either side. You plumb one side to the fuel log or rail and the other is filled with inert liquid like methanol and then to the gauge. This allows the gauge to be mounted inside. For an electrical gauge I am looking into a GM based oil pressure sending unit or similar sending unit that is compatible with an off the shelf gauge. I havent put much thought or research into it but my oil psi is electrical and the range for it would cover an efi motor. Would just need to remember which is which.

 

I'll have to find that Moroso diaphragm thingy Damon. I've looked all over for remote electronic fuel pressure gauges, and all that I found are way too high a scale for the normal operating range most of us use. Any idea how you get the line completely full of inert liquid, so you get an accurate reading? If there's even a tiny air bubble it will give an erroneous reading, so I hope there's a way to bleed it and work.
After all the new technology, and superb tuning aides, a vacuum gauge is still the best tool I've ever found to tune an engine, especially a carbureted engine with no computer to make adjustments on the fly.

edit-I found Mallory and Autometer make isolators, but nothing listed for Moroso at Summit.

 

Might have been Mallory then. Simple looking device no?

 

Yes. A little bulky compared to the lines that would connect to it, but probably plenty of places to hide it. Still no explanation how to get any fluid into the secondary line and not have air? Maybe I'll contact them and ask.

 

I really dont know. Never used one. I'll see what Google turns up.

 

Is this all about fuel pressure gauges? I did not get into this detail with NRE but does 572 naturally aspirated needs a fuel pump? An electric? And what PSI should be rated and to what is pressure reduced before it enters the carb?

How shall the pump be? External or internal?

I think that this auto meter pressure gauge has an electric sender unit so no fuel inside the car... Have a look below
