Also i will say that i have just come from the workshop where we just put the heads back on that xw i was saying about, we are running it at heathcote on sunday, should go good if we can get decent traction happening, we actually managed to balance a 50cent piece on top of the carby while it was running. Didn't stay their long the owner freaked out that it might fall down the carby. I'm also toying with running the AU just for the sack of it, maybe a before and after comparison for myself, not claiming this as a comparison of a good efi tune to a carby cause mine is not, but not 100% sure if i will at the moment, i cooked it yesterday and at the moment i dont have a maf on it, and the diff's not the best either.

i say do what ever you want regardless, especially if you have the spare parts laying around.if bolting on a carbie gets you on the road in a few hours rather than waiting for efi parts,tune,funds etc. have a blast, run your motor in use it as a short term soloution fix the efi and compare the difference.
a carbied au would still beat catching the bus or worse still driving a commodore

Just out of interest? do you know drum brakes have a larger friction area and hence are actually more efficient? why dont you grab a drum brake 9", ditch those silly discs on the front in favour of a set of F truck I beams and some nice big front drums! That way you will have the brake up grade to match the awesomeness of your new retro built uber high efficient street machine.

Seriously leave the carbies to the old school cars. If you seriously want more performance, why not try and shave 200 or 300 kilos off the weight?

Well see i might consider that by no my brakes are functioning fine, but thanks for the suggestion.

I've had a bit of a read through this thread and while the idea is an interesting one (and I think it is purely meant to be a "what if", nothing more - some need to see it that way), I dont think its a very practical one.

To me it seems very much like a backward step in terms of reliability, fuel economy and general setup of the engine. Now before someone jumps me, no, I havent tried it and it's definitely not on my "to do" list, but in my opinion EFI was developed for a reason and there is enough ability now to quite effectively tune an EFI engine just as well, or if not better then, a carbed one.

Personally I really don't see the point in doing something like this but I can see the "what if" factor which is what defines the basis of this thread. Keep that in mind when you reply.

i have tried to avoid getting to involved but here goes,

i have had a fair bit to do with the racing here in Grafton which includes modified,streeters,v8 modified and your run of the mill fords and Holden's.

out of these cars only about 5% run carbies on the engines,the rest use the injected system as it gives them more reliability and less troublesome tuning.

as b2tf said putting a carby on an Au is a backward step.

and if the carby was such a beast and so reliable why then have all major manufacturers gone to EFI?

Yeah im not denying efi as being more reliable, carbies at best are a pain in the , nearly every holley i've had on a car, to keep it running properly i've had to pull apart and clean like every year, and for racing around a track you have the problems of fuel going to bowl sides and so on, i started the thread cause i remembered seing a photo of one with a carb on it, which could have been a 351, all i want to know is how it went overall.

This whole thread is like an add i just saw - It's simple holdens go better.

Now i wanna know what holdens go better than.

Emissions laws, better driveability and just plain easier to live with, simple.
