Hello i have a total new rebuild 292 with these spec:

block: C2AE

Heads: ECZ-G

Manifold: ECZ-9425-B

Carb : Edelbrock  performance 500

Ignition distr: MSD 8383

Here´s my question: I wonder if someone can recomend what springs i should use in the distr

and what ignition timing i should have? btdc

And do someone use the same carb? , who can recomend what needels i should use?

I drive most sreet and use 98 eurpean octane fuel with tripac octane boost

Thanx for a great site, and a nice day to all on the forum from Bjorn in Sweden

no one?

Is it a stock cam or a performance cam..



If it's a stock engine the timing curve should look something like 10 degrees initial advance with another 26 degrees of mechanical advance. The advance curve should start at about 1200 rpm and be at max advance by 3500 rpm



If it is a performance cam you will want about 14 to 18 degrees of initial advance and still 36 total but all the advance should be in by 25-2800 rpm

it´s a regular

how about the carb, does enyone drive with single edelbrock 500?

The Edelbrock 500 is a very good and trouble free carburetor. Edelbrock includes some very good instructions for fine tuning your specific application

I need to ask why are you running your car on 98 + booster ?? What sort of compression does your motor have,  10: 1 ?

My ol' motor is still the original 8.4: 1 and my timing is 14 degrees initial with a total of 38 degrees [no vacuum adv] its all in by 2250 rpm. With vacuum advance I think it was about 45-48 degrees. I run it on 91 no probs.. but thats Aussie fuel I have no idea how it compares worldwide.



"Came too close to dying to stop living now!"

the quality of our gas is no good, they put up to 10% with ethanol in it.

No one who drives single 500?

Our gas also has 10% ethanol in most cases. . Unless your compression is more than 10:1 you should be able to use 91 octane or less. There are many cars running the Edelbrock carburetors here, maybe someone wiill respond. It is a better choice for a street car than a Holley in my opinion

Several years ago I ran an edel 600 ( I think) on a stock 292 55 bird motor. It ran well out of the box, and I drove it a couple years with no trouble. Edelbrock has a chart in the manual, with a tuning grid for all the different models/variations , showing the changes to go rich or lean in stages, and I believe also for full throttle and cruise. Been a long time.



I was told somewhere along the way that the difference between models was the air bleeds, which are not as easy to deal with, but no mention was made as to differences in Venturi sizes, if any. I worked on a 500 on a scub 265' and it did not tune well when placed on a 350' and the air bleeds were the problem. This was on a chassis dyno with a very experienced tech.



Based on those experiences, I'd trust their charts after I knew for sure which model I started with, and that that model was the recommendation for the motor it was on.



My notes are all for after I started blowing 5 lbs boost thru it, and there were major changes across the board. It always went rich over 4000rpm, again, probably in the air bleeds, but this was judged better than lean further down.



These are my recollections, I don't have the tech background to really explain them.



I don't remember a conversion for density altitude, temp etc., but I wouldn't go more than a step at a time unless something was really of kilter.
