Re: Advance timing??

Hesitate to post, P-51, but first, it is retarded timing that makes an i.c.e. start more readily.

However, after an interesting conversation last week with Daytona Carburetor's 1974 founder/CEO Ron Hewitt, who lauds Hudson and Packard above others qualitatively, despite respecting Chrysler engineering and owning more Mopars 1930s-70s than either, suggests advancing our timing strains our engines more than running the factory suggested 6 degrees BTDC, in the case of my fellow 356 owners, even for those running higher compression. Because several longtime 356-engined Packards report happy running at 9, even 10 degrees BTDC, certainly no pinging, one of them running a 288 head for 8:1 compression over the factory's 6.85.

My '47 Super, per a late 1947 Service Counselor sent to all Packard dealers in the day, suggested using one of the new 327 heads for owners wanting a trace more oomph, in my case, 7.5:1.

Ron said if running okay advanced, not a hint of pinging, leave it, but in so many words, says doing so reduces engine life. Please, sports fans....Ron is hardly suggesting this will turn your engines into grenades, just reduces their optimal life expectancy. I'm begging you; read this slowly, consult a dictionary before reacting.

Hesitate posting this because i o n l y....want to hear from those with solid engineering knowledge about Ron's observation of reduced engine life, not retirees and shut ins who want to see their names ever on forums.
