Sounds like a 70 429(possibly a 460?) Crank casting number will determine this, 10.5-1 compression factory rated at 360hp(gross). Shouldn't be too hard to make 400hp from it. D0VE heads are good castings to start with also. Block casting number is probably actually 6015-AA, rods are standard passenger car rods and will most likely do for you expected hp level (with a good resizing and ARP bolts)
Yep, ya got me there. D1=71
