Since you have a 350, I would say it will probably help you. I think the people that lose power from it are 305s, since the stock tpi was made for a 305, so it chokes a 350.

 

I think they will prolly hurt you, so send them to me!!!!! LOL

You should notice a much flatter power band. It should pull to a few hundred higher rpm nicely and the power should fall off a lot slower on the top end. Probably won't make any more peak power, but peak figures are just bragging rights anyways - broad power bands are what win races...... You should be happy .
