2056 still working out the bugs Options

[jmargush]

I am sorting out my recently built 2056 specs below:
2.0 Heads were done by Len Hoffman
CR 8.56:1
Full Raby valve train kit
Stock L-jet throttle body, air cleaner, and intake runners
stock 2.0 heat exchangers
pertronix ignition


It has a miss under hard acceleration.
All the vacuum lines and oil cap gaskets are new and I can't seem to find a leak any where.
So I decided to recheck the timing.
Pulled vac lines off the vacuum diaphragm and plugged, set idle to 800 rpm
timing was a little more advanced than it should be but not dramatically, but I did reset to factory setting.

Drove it and it is even worse than before.

Would the new engine combo warrant a different timing?

Fuel filter is new but my next step is to check fuel pressures and injectors.

Anything else I should be looking for?

I only suggest this because I have done it (IMG:style_emoticons/default/headbang.gif)

Not saying anyone else would.... But be sure you use the correct timing marks on the impeller.

I am running a 2056 with D-jet and have been struggling with timing for a while. But the stock setting when dome correctly seems to be acceptable. There is some good info in another thread I started. Most of it was added by others more knowledgeable than me and who know which timing marks to use.

I am adding a AF gauge to tune it a little better and adjust the MPS.
