Torker 2 vs Performer RPM?

RPM.

What do you like to do with the car?
Street driving? Hot rodding?
You dont drag race it, but it sounds like a drag race engine and toque converter in the car.

I have seen race vehicles that "feel" like shi* cruising around on the street because of very low gears, loose converter, radical cam, monster heads, big headers and loose front suspension. When they stage and let it go, they run like a scalded banshee. Then you go to take a curve and almost die. Point being, set your car up for what it will be doing most.

Big cam and converter slush probably contributes to street driving feeling sluggish like a dog.
With a big cam, reckon you can't get a way with a tighter converter.

What are your cam specs? Rocker ratio? What was it degreed in at?

What heads and what done to them?

What do you mean that your torque converter "sucks"? I have a converter "sucks" story:

I swapped in a 2500 rpm hughes converter in my perfectly running stock 5.4L f-150 which already had headers and better exhaust.
That "stall" converter was a terrible mistake. Truck was a dog after that. Slushy.
Granted it was a stock vehicle but that converter took away what little torque the motor had. It wasnt the converter, it was the fact that I put a street-strip converter into a street only stock vehicle. In otherwords, simply wrong application, poor "balance" of components.

If your cam is a 3500 - 7000 rpm piece, I agree, best thing to do is put in a cam that follows your driving needs and your typical rpm range.

Sounds like with 6" vacuum at 850 that your cam is pretty high rpm oriented or something else is whacked out.

Vacuum advance will give you better street feel and part throttle torque when hooked to manifold vacuum (when calibrated to work properly with your centrifugal advance curve). Of course with your vacuum readings, it might not even work.

RPM is pretty great for moderate engines I think.
