Hi Guru's,
More fettling today. Since I've had the car on the road I've thought the idle was a bit high. I don't have a tacho and I know it's no big-block but it just 'felt' high. So I've been chasing vacuum leaks and found one today. Sealed it, can't find any more, engine still idling high-ish with the idle speed screw on the Holley backed all the way off. Any suggestions? Static timing is 10 deg adv, idle mixture screws are about 1 3/4 turns out vacuum is 17" in drive at idle, 20" in park.
Disregard I found my vacuum leak. Bloody throttle shafts on the carby. *sigh* So I guess now the question is, what is the best down draft carby to fit? Holley 390 Vs Holley 350 Vs Edelbrock 500 Vs Weber 34 ADM?
In addition, the manifold is a standard one that's been modified to accept a 4 barrel - problem being that at the bottom of the tower it's not much bigger than a 2 barrel anyway. I do have a nicely modified standard-to-two barrel manifold or should I just get an Edelbrock....?
