I went with the 377 inch kit. In general I have found that the big stroke changes create several problems such as the one you mentioned. In addition the sever rod angle that most of them create leads to reduced engine life. At my age, I'll live with a few less "ponies" for the sake of street ability and longevity. On the street, a properly built 377 will give you more than enough power to attract unwanted attention from the law.
