308 GTB Vetroresina

As I mentioned previously on this thread we are restoring Vetroresina #19959. I designed and built a stand for the engine/transaxle that can be used in different configurations.
Here are a few photographs.

David, were all the holes in the block where you mounted the block to the stand threaded, or did you use dowels in some of the holes? Nice stand BTW.

No not all of them were threaded. 10 X 1.25 tap did the trick. I have factory align bore shafts for checking the crankshaft alignment and block for straightness(?). Attached photo. An American style engine stand interferes with this process.
Made the engine stand 35 years ago. It has seen many Ferrari motors. Factory drip pan.

Our project is progressing nicely. Attached are photos from a month ago. I enjoy the restoration threads here and try to contribute when I can.

nice. That's the way to do it, blast them clean. not a fan of dipping

 

196 on a dynojet sounds about right. The wheel type actually makes a difference with these as well as the 14" mag wheels are very light. I have tested an early 308 with small wheels and saw 199.6bhp at the wheels, then the same motor made 191bhp with 16" aftermarket QV repops. Regardless, the factory 232 flywheel (with early cams) makes sense and supports about a 15-16% drivetrain loss with small wheels and 17-18% loss with aluminum QV repops.

Seems to be about average drivetrain loss as even though it's not turning 90 degrees through the gears, it still has a couple drop gears to transmit the power which makes up for the lack of a turn at the pinion. Most cars direct power immediately to the mainshaft from the flywheel minus drop gears of course. The drop gears are largely responsible for the lovely 308 gear whine we all know and love

 

Nice Vetroresina coming up for auction at RM Sotheby's Monterey, August 18-19, no reserve.

The RM Vetro is 19397, previously sold at Gooding & CO Pebble Beach 2015 for $247,500. It will be an interesting data point since it is being sold NR. Restored early US spec wet sump claimed to be the 1st US vetro built.

Makes me wonder about the reason for the selling of the car. Obviously bought on the top of the market, so selling it now would not make much sense, moneywise.

 

It is being sold as part of a 13 car collection RM is calling the "Ferrari Performance Collection." Some pretty nice cars:

Another interesting VR on the market is 19211. It spent most of its life in the US and at one point had flared fenders, modified suspension, center lock wheels, etc etc. (Plastic Fantastic | Issue 110 | Forza)

Appears to have been restored to original specs and on the market it Italy:

This weekends project was to build a fixture for working on the cylinder heads. I made this from scrap we had in house.
It will allow several operations to be done while minimizing the chances of damaging the cylinder head gasket surfaces. Excellent for honing valve guides (my primary motivator)

Looks neat.

Clearly, the " only two owners" comment is non true.

 

#19397 (US car) up for sale at RM in Monterey. Red with tan, odd?

I have been in touch we the people at Glass308 but I stumbled across a different website focusing on Vetroresinas and can't seem to find it again. I was certain I bookmarked it but its not in my records.
It may have been Dutch or from the Netherlands?

 

You might be thinking of the 308GTB Registry? The Ferrari 308 GTB Register It is for all carbed 308GTB's, not just vetroresina specific.

 

That's a good one but not the site I am looking for.

 

Is it the Nederland register which neither focusing only on vetroresina but at least on cars in that country, you're talking about ?

I'm afraid that's not it either. The webmaster took the time to publish photographs which illustrated the differences between the Vetroresina and the wet sump steel cars.

 

I don't know any other vetroresina register, I'm curious to have this new!

In 308-328.com, there are all the differences details on pictures between the two versions but there's no register for GTB....

Otherwise, there is a local register in Belgium but there's no illustration either....

I keep searching...

interesting that they show on image 11 that the roof is not connected to the rest of the body. Is this common in all vetroresinas? havent seen it in many

 

Yes, all vetroresinas have the "A" pillar seam. Some may have been filled during a previous repaint but it is there. Here is a thread with some of the differences between fiberglass and steel 308s. http://www.ferrarichat.com/forum/308-328-sponsored-yellow-compass-group/457394-308-gtb-vetroresina-vs-steel-body.html
