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? |
