Yes, another timing question!

The Torker and Team G are proven single plane big block manifolds and certainly have their place (230+ @.050).

While the cam specs would be nice to know, what is your actual compression ratio? 8:1 compression and big cam will make any engine sluggish.

Play with giving it more timing until it pings at WOT. If your dynamic compression ratio is fairly low, you may get to the point where you either lose power or have trouble starting before it pings. You're searching for the best WOT performance (use a stopwatch). You may find that this occurs well before you advance the timing to "highest idle" and hurts your low speed throttle response. Hooking up the vacuum advance should help. Assuming you have a fairly large cam, you may get a smoother idle with the advance connected to manifold vacuum instead of ported (engines that run best this way would do better with more compression and less timing, but do what you need to do with what you have).
