SD build
I've got a 73' green SD car myself. Mine is much closer to stock than this but still runs great. I've build several of these engines over the years and here's my thought on your build. You didn't mention having a crank so I would get a forged 4.250 crank (versus the 4.210 stock stroke), use 6.8 Eagle rods, get Ross pistons to match with a moderate dome to get you to around 9.5 to 9.75 CR. Use a hydraulic roller camshaft and don't put too small a cam in it. I would go with something like the the old faithful cam (236 I 245E @.050) but ground on a 114 LSA if you are going to run the factory SD manifolds. When you buy the manifolds have them opened up to 2.5" Modify the intake plenum or send it off to SD performance to be worked. Put in around a 2800 stall convertor. Zero deck the block and hone it with a head plate. The car will flat out get with this combination!
