Just a few questions. Are you tapering them in the back or just a square box? Also are you having to change carb jets? Is it affecting your nitrous tune? I am running a small block windsor should trap around 120 in the 1/8th. I have a 3 inch cowl now and I know that it is hurting the performace cause the hood is too close to the carb. It is an svo scoop in the middle so instead of buying a new hood. I am going to make a box and cut a hole in it. Just wondering how much is going to affect the tune. I have a race at the end of the month and won't be able to test it till race day. What do you guys think.
