Yet another 273 build advice thread!

After reading all the theoretical opinions about 273’s and cams. My first 273 was in a 1964 Barracuda TRW forged 10.5 pistons, good valve job, milled just enough to flatten the block side, Offy intake, 600 Holley, 284 duration solid cam, Mallory all mechanical dual point distributor, stock exhaust manifolds, 65 Formula S exhaust with a 4 speed and 3.21 8 1/4 rear. Ran strong about the same power to weight as a 383 Road Runner equipped similarly. Next incarnation swapped the 273 heads for .040 milled 72 340 J heads, used 340 hydraulic cam and lifters, 71 340 intake and TQ, 72 340 electronic distributor. What a monster engine. No way to go slow, quick revver, whole new level of performance. A 273 in an early “A”, even an 8.8 to 1, is Not comparable to a 318 in a Monaco. 360? Did anyone ask?
