78 D300. and a 6.1

I'm gonna use the stock 5.7 hemi that is in my 64 Polara 500, and the Polara is getting a stroked 392ish. Gonna keep the 727 in the truck just because I've already done eng/trans once and I want to keep this simple. No ac, power steering, just all engine......but that could change. Right now the truck is running/driving and I'm still in the process of getting parts, mainly pistons, for the stroker. So it is a ways off, maybe next summer.
