You could start with 36* and tune from there. Also NGK plugs are used on a lot of bracket race BBC. #8 heat range for gas. For aftermarket head like Dart with .750" reach # R5671A-8. Jetting in high 70's range. Lot of variables and not enough info to be very precise.

Tähän ei ole yhtä oikeaa vastausta, koska kokonaisuus ratkaisee, mutta suuntaa-antavasti pääsee alkuun. 12:1 puristuksella oleva 468 tykkää usein ennakosta noin 34–38 astetta, mutta tämä pitää aina varmistaa dynossa tai radalla ilman nakutusta. Sytytystulpiksi kannattaa valita melko kylmä lämpöarvo, jotta kestää kuormaa. 750 AED -kaasarilla pääsuuttimet osuvat usein lystikasinot-fi jonnekin 78–84 väliin, mutta se riippuu ilmasta, polttoaineesta ja säädöistä. Lue tulppia ja seuraa vetoa, siitä saat parhaat vihjeet hienosäätöön.
