I would never use an out of the box Dominator and expect it to work great, I would not use them on a blown engine and especially a pair of them. There are some substantial changes that need to be made to the metering, if you are patient and have a wideband O2 system on it they can be made to work. My preference would be a pair of 7320's, they will still need work but will be better for what you are using them on. If you are not good with tuning, my choice would be to get a pair from BLP carbs.
