Ferrari Mailing List: Re: 308 Engine rebuild

[Peter Pless (ferrarilist]

Hi Peter,

 

What you are proposing to do with the Alfa carbs is pretty much exactly what I did with my BB512 in the late 80s. I had injectors installed into the inlet manifold just under the carburettors and took out the guts from the carbs, giving better air flow too. I would have done that with the 308 too, probably, but the inlet manifold wasn’t long enough.

 

With the bolts v studs…I just wasn’t keen on removing studs that had been in place for 40 years, and it was just so unnecessary. There was no reason for the throttle bodies to be that thick at that point. So, just a bit of grinding and it all worked out. PLUS….some people prefer stock, and just in case I ever had to put it back to ‘standard’, I wanted it to be as straight forward as possible.

 

I’ve attached a photo of the throttle bodies I used (I hope it goes through)…the fuel rails and in the V and not visible. The whole transformation has left it looking reasonably stock, unless you look very closely. Most people don’t even notice. Of course, it still sounds wonderful with a RHD car and the drivers ear right next to the air intake!

 

I was thrilled with the result when I did this to my BB, and I’m just as thrilled with the result this time too.

 

Peter

It’s not just for performance but making it future-proof; today’s fuels are really formulated to be delivered through high-pressure fuel injection systems. It just seems “off” when it’s run through carbs, even though I use the highest grade available here (94 octane, no ethanol). A friend is going to adapt a discrete set of injectors inbetween his carbs for his Alfa 2600, for the same reasons (will use the carbs solely as  throttle bodies and rely on the injectors to deliver all of the fuel). I wouldn’t hesitate to do the same conversion for my car.

 

Interesting point about the need for bolts instead of the original studs. I see their point because why would the throttle bodies have to come off in the future? But, I do prefer studs over bolts and appreciate your work to modify them. From what I remember about the online promo literature, the photos showed the throttle bodies arranged with the fuel rails on the outside of the engine “V”, thus necessitating the need for throttle linkage that operates in both directions, whereas the carbs are arranged in the same orientation, thus, the linkage works in one direction. These throttle bodies could’ve been mounted the same way as the carbs?

Lol…well, it’s all relative. I think a Toyota corolla might be faster!

Regardless of whether you tried to or not, you ended up with a performance machine!

No weight reduction on the car, but I could certainly use some personally!

 

I wasn’t trying to make it a performance machine. I was trying to make it the best it can be.

Very sexy!

 

Nice numbers on the engine rebuild too.

 

Have you done any weight reduction?

Yes Lash, that’s the one.

Peter, is this for that Azzuro California GTB?

Just rebuilt my ’76 308GTB engine. Did all the usual things that one does with rebuilds these days, plus installed Euro cams.

 

I also have 8 throttle bodies and injection. Looks stock. Sounds stock (very important) but makes the car run great.

 

270hp @ 6750rpm

312nm @ 3500rpm

 

Pretty happy with that result.
