Do you have a source on some 4v heads already? I have heard they are hard to get.
It all depend on what you want to build the car for (mild street, drag racing, high hp, high rpm).
The 2v heads...

Interesting, why would Ford hide an obvious safety feature it in the glove box?

A 1966 car has emerg flashers?? I think that was added-on much later.

There are 2 contacts inside the bulb socket, one for...

I would say it's your headers making most of the noise. Go back to stock Ford manifolds or iron hi-po minifolds.
I still say resonators would help too, as would the stock Ford Mustang mufflers (not...

The stock style mufflers that came on my Mach1 were real quiet (and quite restrictive).
It felt like I picked up about 15-20 HP just going with Flowmaster 44s, and got much more sound (which was...

You didn't say what engine you have. A smaller engine will get more noticable MPG gains from EFI. A big motor will see some gains but they just suck gas anyway.
Also what about your budget? Most new...

That's a very common complaint when rebuilding carbs.
Better find the check balls or get some new ones, that probably is one reason why it's running bad. Didn't the rebuilld kit have new ones?

I'm not a carb guy either. I would suggest getting a new Edelbrock carb about the same size as the one you have. It ran great right out of the box for me and wasn't very expensive. The best part,...

Unless you need the origional, just buy a new one, they're around $10 or so.

I guess you could soak it in carb cleaner and let it dry out.
If it's a filtered cap (no hose), just buy a new one.

Check your PCV valve too, it also should be getting vacuum from the base of the carb.
But more likely the breather is clogged with oil and gunk.

That cap won't work with origional style valve covers. You need a screw in type breather. Use a filtered breather or hook that tube where it is supposed to be, on the air filter housing.

I think that's one of the reasons most MFGs discontinued making converts in 1974, when the gov't mandated 3-point belts in all vehicles.
I guess you could try to custom retrofit a belt/seat system...

48 Sqft is only a piece 8ft x 6ft, enough to do the floor and maybe a little piece left over. I'd say double that if you want the ceiling and elsewhere.
