I've installed Jasper GM 305's and 350's before for a buddy and he was very satisfied with them. I have another buddy that bought a Ford 302 that is still sitting on an engine stand in his garage. For me I rebuild my original because of the matching numbers issues along with originality. That isn't a concern usually in a modern run of the mill vehicle though and the Jasper makes more sense. - 2ruggedforyou (Review found on City-Data)
