lets revisit timing

TT5.9mag said

Even stock 10:1 340s made more than they were advertised at. I think the realistic number was likely about 320. So going from “optimal” timing (call it 34-36 deg) and pulling 6 degrees out of it I am of the opinion that you would notice a difference in power.

Not about timing really here but that theory of them making more than 275 up to 320 stock is very debatable....my '71 340 s/strip cuda ran down the track back in the day and weight/mph said 301fwhp and that was with an ally intake 750DP, .484/284 cam and small tube hdrs. it ran real good@36 total on leaded 4 star fuel we had then which was approx 97 octane. Upped that to a .590 sft, 850DP and race hdrs and it was 367fwhp.
