Desperately need experienced opinions on Engine Identification

Id pass. 273 blocks are cheap. EGGE 4bbl pistons are available. build a 67 with those pistons and a $100 273/4 intake found here often and you got your self a 4bbl 273. choose a modern cam and a distributor of choose and your set. Heads were the same. I'd build a 318 with the 273 top end. More displacement, much more torque, same HP, same look. I spun a rod bearing on a 273/4 went cheap and bought a $100 67 318 short block and moved everything I could off the old 273/4. Damn thing was way quicker than the 273/4.
