I have just recently purchused a 65 riv and parts car and am planning my resto. This will be my first resto and I'm excited to get started. Until I can get a better look it seems I have one 425 nail and one 401 nail - unsure of trannys at this time. I would really like to pack some punch in the engine (most likey use the 425). I'm going to post my questions about that in the nailhead section. Just saying hi. Ill post pictures later on.
