Ok, today's challenge...  how on earth do you get the heater box and A/C out?  from pics I've found, the heater comes out first, but the little brace on the lower front that holds it up seems to be welded in place and the unit won't drop down enough to slide out.  on the A/C unit, is it just the two bolts up high in the rear, or are there bolts along the lower edge of the dash also?  seems like there would be, but I haven't found them yet...

She's VERY close to reinstalling the engine...  chasings hoses and belts at the moment.  I have the correct valve covers and DT Emblems, but I kinda like the aluminum ones for now

  Mike, I'm not dead sure if at that time the maker was called just "Asti" instead of later "Gate Asti", the motor number is MP3920-31... The overall number MP3920 was apparently used for years and years, the -xx number will vary with the actual spec.  But its entirely likely that yours is fine, or that any electrician could clean it up.

I also guess that the UK mini fan blade would work. The Goose heater box is 'shared' with the Mini Innocenti (the Italia version of the Mini), and then only the chimney is added on the IPRA Goose box.  Somewhere on my shelf there I have NOS motor and also a used Innocenti box...

For the AC, I think the motor is a Behr, made in Ft. Worth TX . But that basic style was used for decades (esp, 80's Alfa Spider), and even I think the retrofit Pantera AC fan solutions just may fit. Trying to find genuine 60's AC components is damn difficult, it just seems that not many cars, really, had AC...Lee

ps. btw, I think your valve covers are pretty cool, got a picture to share?

Mine is in very good shape aside from a questionable bushing on the cage end...  Wasn't turning at all initially, now it's turning ok...  Could be better though...  The bushing might clean up. 

Thanks for the Innocenti info, always good to know possible sources if needed...

A/C investigation is pending...

I'll post close ups of the valve covers soon...

MH

For clarity's sake (and my old guy sanity!) is it possible to place a picture of the "type" of AC/Heater system youse guys are a working on???    I'm guessing that you are working on the later "in dash" AC vs the most common "underdash" version???

The conversation was throwing me, in that the under-dash system was made in Spain.... and you were mentioning non-Spanish vehicles!!!

Good stuff!!!
Steve

Steve, Mike's car is 8ma898, so almost perfectly familiar Ayacsa AC on the right  and separate IPRA box to the left for the heater...So Spanish and Italian. I haven't ever seen pictures of the in-dash solution at 8ma1100 and later.

The only reason for "almost perfectly familiar" is another twist on the AC box for Mike, where he doesn't have a glove box (he does have a glove box door...) and instead of the glove box he has additional AC vent piping to exit by the driver... But that is all a different story Lee

Well crapples...  I had a full reply typed out and got distracted and never hit send.

Quick version is "what he said"

+ I cleaned both heater fan motor and condenser fan motor and they're both working fine now...  Condenser fan motor was working before, just made an odd sound...   Also having new hoses made as well as condenser itself...    They goal is to have A/C working...   Even sourced some of the forbidden juice !!! (R12).

I might replace A/C fan motor in hopes that a newer one will move more air...

Yes, 898 has additional vents left and right under the dash by each door jamb...   and an interesting manifold of sorts feeding them...  I spoke with Bill Lavinger (owner from 70's to 90's) and he said those were factory...  He owned three Mangustas, so I knows them well...

MH

Michael,

I believe that those valve covers "could be" period Edelbrock or one of the other big names.......I have a set somewhere but couldn't put my hands on them if  you gave me another Mangusta!!!  (But I'd sure try!!!)      The logos look either custom made or modified Pantera versions not the "pork chop" version the Goose typically comes with....

I would also implore you to install a thermostat in the engine.   If you've already modified the 90 degree fitting off the front of the intake to accept a t-stat, well then good job!!!! 

Without one, you are begging to wear out your engine prematurely.  It will never warm up....to proper operating temps!  ....OK perhaps not never, but perhaps not as quickly as it should......to get your heater working ASAP for winter driving!!!

I had a think 3/8" or so piece machined up to fit between the pipe, and the intake.  It had the recess carved into it and fit using 2 gaskets and slightly longer bolts to secure it.    Worked like a champ! Quick warm ups!   NO ONE will ever point it out that it's "not factory"!!!!

Cheers!!!
Steve

Ooops! Missed replying to the AC thing.....

1) NEVER have seen AC venting at door jambs.  Yet.   Not that they were not put in place by the factory, but this is the first that I have ever seen mention of it.   Not sure what all Bill L has seen or owned, but pic's would be super!   I always wanted to put a vent on the drivers side of the steering wheel!

2) AC Fan Motor: YESSS!!!!! This is the ONE, ok ONE of the things that dearly could use more HP!!!  The fan motor for blowing cold air into the cabin fails......  I had heard of a guy in Santa Cruz that could rewind them to get more RPM's but failed to push it further.  TOOOO much apart....needed to go back together....

In the end, with new rotary pump, new hoses, lubed bushings in the condensor fan out back, and a good charge of R12.....  that AC unit blew cold air something fierce....sorta like a small kitten.......when it needed to blow LIKE A BIG LION!!!!     Many times while driving the Goose, it was simply easier to roll the window down just to have fresh air blowing around vs trying to kid yourself that that measly sickly fan motor would push enuf air to cool the cabin down!!!!

I wish I could have spent more time exploring another electric motor for that feature! It sorely needs it.

Ciao!
Steve

Actually, Gary (previous owner) had that snout redone in SS and had a thermostat space included.   In Texas we don't have much need for a thermostat in our cars...   and I will definitely never take the goose out if it's bad weather...   Generally keeping it from overheating is a real concern here...  Getting the heater working is really more of an OCD kinda thing...

But...  If I were to put one in, this WOULD be the time to do so...

The cast valve covers look pretty old school, which I like...  They seem period correct for a '69 model...  The emblems are nicely done cast pieces, but their origin is unknown...  I used the 3M thin double sided tape that has the grip of death when I put them on...   So far they've help up nicely. (5 years)

MH

AHAH!!!!
You have Gary's car!   I recall him doing that now....somewhere I have pic's of what he did!  VERY NICE work!

TX weather or not, the T-stat is a smart thing to do.  Doesn't cost you poo to put in, and it really doesn't hinder keeping the engine cooler...... that's all radiator fans and water pump capacity for better "water movement".   I ran it all the way to Phoenix from CA, twice for the POCA national show, and didn't even worry about it!   If you have the original FIAMM radiator, you just need better fans and shrouding.  Put the fan switch on relays....!!!   The radiators were well built!!! Just heavy!

Still have the old C9AF-U Holley on it??  Good carb!!!  I love them....735CFM with the vac secondary and heated choke.  Put them on 428's I owned, 390, and 351s! They just work with minor jetting for proper fuel/air ratio depending on engine size.  Will need another soon like down the road!

Cheers!
Steve

I'll take some pics of the side vents and manifold...  It's definitely NOT some homebrew setup...  I'm wondering if it was a design used on the Ghibli or other such cars that DeT decided to try out on a goose... 

Lee and I both have the solid wood steering wheels...  No leather sections at all...  So DeT wasn't above randomly trying different things...

MH

Yeah, Steve, I think the improvement on 8ma898 AC venting was to remove the backpressure from the mis-applied Ayacsa unit. Just cranking up the horsepower probably less efficient: As you know, the Ayacsa unit came with 3 vents, but the right-most vent was sealed off by DeT either for looks or to somehow prioritize air to the driver...But you can see, this blocks the most optimum outlet for the air and then forces all the output thru a rather narrow neck. Note also on this  picture (the NOS, were we sleeping thread) all the holes in the top panel--clearly an attempt by Ayacsa to let the thing breathe a bit without getting noisy-as-a--clogged-vaccum-cleaner...

  Mike's car is best described in a Binky episode--a glove box door, but no glove box---instead, air tubes that take the air to under the driver's left dash...



And yes, the Cal-custom look for the Valve covers is my 2nd favorite look...my favorite is the Detomaso Weslake conversion I have only seen in a very old Ford 302 hop-up book... (see pic) Lee

Gary & I have been friends for 25 years...  He was my co-piloto when we were racing La Carrera Panamericana in my 230SL.  In fact, around 2004 he told me he wanted to buy a Pantera and I found 898 for sale online and sent him the info...  Next thing I knew it was headed to Texas...

I bagged-n-tagged the original radiator fans and installed twin tractor fans, they work great.

I called Gary when I was wrestling with that downtube that was corroded...  He said it was a "right place at the right time" kinda thing on having that snout redone...  It was definitely well made...  and Gary likes to plan for any eventuality, so he had them add space for a thermostat.

Yep, still have the Holley carb, it ain't broke, so I ain't fixin' it...   I considered going to an EFI, but I kinda like the old Holley...   Runs great!!!
