I tried running with less jet and it didn't like it. Expect not enough signal from the 304 ... but each build will be different. It was a Hornet with a stock 304 from a '78 Concord, had lots of miles on it and got hand-me-down parts from my Javelin as it was upgraded.
Distributor was the stock AMC Motorcraft and stock box. IIRC, ran 12-14deg. initial, 35 total in by 2800 rpm. Vacuum advance was mechanically limited to keep it from giving too much as it would sometimes ping on cheap gas. Hope this helps,RD. |

We would suggest to put in the Silver or Plain Springs, and why is the calibration at # 8, # 23 would be a bunch better. #8 is leaner than stock calibration, # 23 is where we (Edelbrock) will suggest! Dennis |

Changed to 23 tune and it runs much better. Still going to mess around with it bit more with the bove info and play with the timing a bit.
Thanks all for the replies |
