Drivers/Racers - 4 Speed Driving Lesson Required

Good morning, since you are using a smaller displacement engine with a short 3.31" stroke in conjunction with 360 (308) heads, it is going to need a bit of rpm to make its power. Of course this is dependent on camshaft profile also. With the upgraded intake and cam, I would guess a good starting shift point would be 5000-5500rpm. Even a stock 318 should easily pull those rpms with little difficulty. Again, this is going on the limited info provided. Perhaps you could share more info on vehicle, gear ratio, and intended usage.
