Help, I have a ford 460 and at this time have a 600cfm Holley with vacuum secondary's sitting on a Torker ll intake, everything else is stock, and have a problem tunning it right. Always seems to be either running to rich or to lean, I can never find the happy medium. I have wondered if I need to upgrade to a 700 cfm or there abouts because of air or just keep what I have a re jet or something any Ideas will help. Thanks

If you have a 460 that truly needs a torker, then you need a lot more than 600 cfm. Having said that, the tuning problems would probably only show up at high RPMs.

We need more info, but my guess is that you have a gross mismatch of parts somewhere, probably the intake. Unless its a race-only engine there is no need for a torker intake with today's dual plane designs. A single plane intake gives a less steady vacuum signal to the carb making it much more difficult to tune.

What cam, compression, other modifications, and where is this engine used; street or track?

You might want to talk with a tech rep from Holley. They can zero in pretty quickly on the cfm you need. I'm running a 460 with mild Edelbrock performer cam, performer rpm manifold and a 750 carb. This was the recommended set up per Edelbrock. Holley may differ but I'm guessing your 600 is a bit on the small side. These 460's seem to love sucking down as much gas as possible.

All of the 460 my dad has had (and he's had a lot) all had 750 holley's on them. 600 is too low for even a stock 460. The one in our 78 super cab has a 750 on top of the bone stock 460 and we have no problems tuning it. The main point is if you want to have it running right theirs no other way to go.
