Want to know what 5 speed transmission you guys are running out there. Why a 5 speed you ask, because I have a 1965 and I don't want a huge trans tunnel on my car. I will have 600+HP and money is not really an issue unless it gets really up there. I'm looking at both oem type that is beefed up or a full race trans. Only problem with full race trans is none I have found come with any sort of overdrive. 5th gear is always 1:1. Would like an OD because this is not a 100% track car.
