Just cant get it tuned right 440

Gear and stall converter very important to make good power You have to match your power band got it.Think of it if you cam starts @ 3000 you need intake,gear,convertor,all to start at the same time,I have seen it to often guys stick in a big cam that starts around 3 grand and wonder why she is a dog off the line with stock stall convertor.got to get thoesssss revs working just at the right time.
