Quote: I don't think the heat riser will make the diffeence you are looking for on his car. I don't think the choke will work a whole lot different blocked, mine is and the intake gets plenty hot once the car warms up. He could just wire it open and live with the poor cold running temper, it doesn't tae that long to warm up anyway.
Do you have a six pack? With your crossovers blocked does your choke still function properly?
