Someone just offered me a 425 low mile (I imagine they mean under 100k) nailhead fer the Plymouth! Or an "A" family clean SB. Now a Dodge SB would be the easier fit, BUT the nailhead is genius! Would like to hear some opinions if nuthin else, I have a lot of tech standpoint on this already, just want to hear what people think. Streets and any other SBC (BBC for that matter) will refrain from Cheby sympathizing.
