Distributor

Hi guys need some advice about a new distributor.
Over Christmas been using the 66 and it's just brilliant.
On getting to know it better, I found that the distributor has NO vac or mechanical advance at all! Although it starts and runs great.
Bearing in mind that I have no access to scrape dealers etc and I need to buy from eBay or summit, what do you feel is the best way to go?
I have seen gm style HIE units at a very good price, but not sure how well something that big will fit?
Checked out Petronix but that's much more expensive, and most of the features will never be used on a truck that will never see 4 k.

What do you think is the best way forward?

Thanks for the help

How did you determine that the mechanical advance wasn't working? Because if you're not getting any advance other than the initial setting you are going to have a really sick running engine that will eventually burn up the exhaust system and probably some exhaust valves to boot.
If you don't mind having points you can usually find NOS Autolite or Motorcraft distributors on e-bay. I got one recently for less than the cost of those Chinese HEI units. I just did a quick search and came up with this one NOS OEM Ford D3TZ-12127-H Motorcraft DA-1251 Distributor Tag # D3TF-12127-HA | eBay

First the easy one, no vac canister
Then if I take off the cap, and try to move the rotor arm, it's locked solid.
If I put a strobe on the engine I have a couple of degrees movement (advance) as the revs increase, but it's all over the place. Not sure where that's coming from. MAybe it's built into the crane electronics module?

Cheers

You should be getting somewhere around 28 degrees centrifugal at around 2000 rpm. So if your initial is 8 degrees you should be seeing around 36 degrees at 2000 to 2500 rpm.

I'd buy a rebuilt stock type distributor. You'll need to get smart on distributor curving, it's not difficult just "tedious". Alternatively you can send it (new or old) off to one of the distributor rebuilders and have them curve it for your application. The problem is a lot of vehicles used the same type distributor but the innards are setup completely different. Never know what yer gonna get.

It's a 351 bored out to 360 (I think) running headers, true 60 mm duel system and a 570 vac secondary Holley on a cast iron 4 bbl manifold (I was told it comes from a Thunderbird)
Problem in the UK is there is not a lot for FE's, small block chevy's are very plentiful but not Ford.
Best for me is to get something of of one of the major resellers.

Anyone used the Petronix ones? Would I need a new coil?

Thanks for all the help

They are good systems. I'm guessing that you are considering a complete new distributor. You will have to buy a new coil. And it will most likely have a performance advance curve and require some tuning for your engine. And if it breaks where are you going to get a part for it? If I lived where parts were hard to find I would try to stick with Ford parts.

That's my problem
I can't get ford parts easily. If I could get a new replacement I would. These engines have never been used in Europe, and there are no distributor builders any more.

A rebuilt distributor and some .50£ springs and a timing light is all that's required. Faron Rhoads is a well known distributor guy who would curve a distributor and send it off across the pond. The alternative is one of the modern replacement distributors that make curving much easier by the end user.
