This is interesting: A 2 valve engine with single distributor(used through 79 Euros, appears to be OEM Marelli) with a GTBi Kjet manifold (80-83) adapted to EFI. MSD box possible also present. The original marelli single distributor can be thought of of two distributors crammed into one body. To verify, if you are wired for two coils, it's the original euro system. That's a bit weird to have one MSD box. If you have only one coil, it is a custom system or likely driven off of the EFI box. Based on what I see so far, anything is possible. The 'electronic' distributor simply means it does not have points. MSD's work with either system, but would have thought it would require two boxes as there are really two seperate ignition circuits crammed into a single dist. body as said before.  Need to check which EFI driver you have. It's strange that they went to all this trouble with EFI and kept the distributor - many EFIs have ignition drivers as well. There are much more expert folks than me at this here, but this should be fun to figure out. If you wanted to go back original, you could get a set of manifolds and Carbs, assuming this is a '79. best rt | ||

Ed... None of the single distributors were electronic. Dunno what to tell you about EFI, sorry. Over the years, I toyed with electronics, but always reverted to the "good 'ol" mechanical systems on the single distrib. cars... they just plain work (If it ain't broke.....). Best regards, Andy | ||

How do I tell if I have a: non-electronic single distributor cap = 95300045 rotor = 95300317 electronic single distributor cap = 95300046 rotor = 95300317 The dist. is definitely electronic since it has the MSD ign system on it, but was the dist. cobbled to electronic? Anything about the EFI system? Ed | ||

I don't want to take business away from Jeff and Ferrari UK, but if he doesn't have what you need, you might also check with Dennis McCann (www.allferrariparts.com) and Superformance (www.superformance.co.uk). Of course, first it needs to be determined exactly what car you have... | ||

I messed that single vs dual stuff up as Andy has it right -- all Euro (standard) 308 B/S use a single distributor set-up. The switch over at the chassis/type SNs listed below are for "single dist non-electronic" vs "single dist electronic". The non-electronic single dist uses yet a different cap, but the same rotor so the PNs are: non-electronic single distributor cap = 95300045 rotor = 95300317 electronic single distributor cap = 95300046 rotor = 95300317 | ||

All of the early Euro 308's had single distributors, driven off the "front" intake cam. Try GT for a rotor... they have 4 new single distributors in stock ($950 ea), and I'd guess they have rotrs, caps etc as well. Btw... the single distributor cars are INFINITELY easier to time/tune than the dual setup! There's a block-off plate for the "unused" drive if you convert. Best regards, Andy | ||

Oops, thanks Steve, I stand corrected on the distributor issue... | ||

Ed, The single distributor set-up is the Euro version, not offered in the USA. Either the motor is a Euro motor, or USA, converted to single distributor. Not a big hp difference for that motor between USA and Euro (205 versus 214 I think). I hate to tell you this, but your friend has a true "franken-ferrari" and like Steve, hope he didn't pay more than $15k or so for this car...I hope less, at LOT less. Can't say anything about the EFI system, but the stock system is a Bosch mechanical (continuous) system. | ||

Ed -- I checked the 308 SPCs on the FerrariUK site, and you're right that all of the '80-'82 "i", both Euro and US versions, have the twin distributor set-up. The single 308 distributor was used on the later carbed Euro 308s (after SN 23561 for GTB and after SN 23265 for GTS) -- is this '79 you're working with a Euro (standard) version? Based on the '77-'80 308B/S Euro SPC what you need is cap 95300046 (L210.00 price shown) and rotor 95300317 (L32.40 price shown) -- any possiblity Jeff? | ||

The 2-valve 308 engine in the photo shows two distributer caps with 4 wires comming out of each. Why does mine only have one distributer cap in the back with 8 wires? What is the difference between the two engines? Any ideas about the EFI? Ed | ||

All. Nice project car. Genuine Distributor cap 2V #115518 $248 Rotor arm - problemmo at the moment. We are trying to get some made but for some reason are having difficulties. Hope this helps anyway. Cheers. | ||

Ed -- Here's a clearer picture of a 4V rear camcover:  I'd be very surprised if Jeff Howe at our FerrariUK sponsor couldn't help you with the rotor & cap, but be prepared for a price shock (not the FerrariUK doesn't have reasonable prices IMO -- it's just that the 2V "i" rotor & cap are in that class of F parts whose prices seems to defy logic) -- I hope your dentist didn't pay more than $10~15K for such a needy and modified project... | ||

So, I have only one distributer with 8 wires comming out of it and I need to buy a "2 valve (GTBi/GTSi) rotor, that may be rather difficult to find." Who has a factory distributor cap with 8 wires for sale? I looked at the sponsors of this website and did not find what I need. Thank you Ed | ||

Ed -- The tip-off that it's actually a 2-valve 308 engine is the shape/form of the camcovers (in addition to the air plenum shape). Compare the relationships between the oil fill cap and the #1 spark plug hole: 2-Valve 308  4-Valve 308  | ||

I think the intake plenums is cobbled for the electronic fuel injection system. I thought Ferrari only had manual fuel injection. My dentist bought the car and it does not run, so I am trying to help him. Ed | ||

QV intake plenums were a different shape and painted red. ALL 308 engines are "twin cam". | ||

"that appears to be a 2 valve intake plenum (GTSi/GTBi)." How do I tell if it is a QV? 4 valve. It looks like twin cams. "What is the long snorkel thingy on the left, for the oil cooler?" The air intake. Ed | ||

BTW, if it is a QV rotor you need, those are readily available. | ||

Wow, what a mess is right! Actually, that appears to be a 2 valve intake plenum (GTSi/GTBi). What is the long snorkel thingy on the left, for the oil cooler? Factory caps are easy to obtain; if indeed, you need a 2 valve (GTBi/GTSi) rotor, that may be rather difficult to find. Be sure and get a factory distributor cap, as there have been some posts recently of defective reproduction caps. Ask before buying. You should start by checking with the sponsors of this website. | ||

I have a 1979 308 with a QV engine in it with only one distributor on the front head (near front of car) and MSD also EFI. The distributor cap is a mess also the rotor is loose. I can't find any parts to repair the engine. Can someone help please. Ed    |
