67 barracuda notchback restoration

Good question DR. I have a 360 short block, and a complete and nice running 1974 318 out of the dart. I was thinking 3 things as money allows. Either do a quickie rebuild of the 318 with a mild cam and run that until i can rebuild the 360. Or i can rebuild the 360 from the get go. Problem w that is funds. Do i go stock stroke 360 or a 408-410 inch 360. I am going to try to build it into a sleeper thats dressed out like a 273 so a stroker would make the same power as a heavily cammed high compression 360 but with a milder cam and a little less compression so it wouldent be as rumpity bumpity and i can more easily hide it. For right now i have the 318 in there so i can mock up all my wiring and other items. Then its all going to be pulled back out.
