ok running a 346 with a ls6 intake making around 450rwhp,i shift at 7000 rpms and the ls6 falls off, cant decide to go with a fast ar a victor jr setup,what is your opinion?

 

need more info on the engine/heads and mods

 

or GMPP?

 

ls6 heads and a unknown cam, got the car already built, forged bottom end,fixing to put 215 cnc trick flow and a cam change pretty quick, gonna try and make right at 500 to the wheels

 

I would search in the drag section. But a single plane with a 4 barrel throttle body is the only way to make power N/A. Also a Cam spec for a single plane will be a big improvement. But if its a street car I would go fast intake.

 

like he said if a street car go with fast

 

i rarley drive it on the street, mostly track,so the 4 barrel throttle body is better than the regular throttle body on the victor

 

or try a proflow intake. cheaper then fast and should make more up top

 

The elbow and throttle body kill power in most if not all NA dyno sheets I have seen, but guys run a 4 barrel throttle body with a carb hat and do ok.

 

I have had both on my car. The vic/elbow lost tq all over on my car but most down low. The hp went up by 10 on the topend and it pulled to a peak of 7,200. The fast had more tq where you need it for a street car after a port made the same power but at a lower rpm of 6,700rpm's. I went faster on the fast at the track then with the vic jr. My car is not a full race car but for me,the fast performs better.

 

I would do a fast. They make more power.
