I recently replaced the Autolite 45s with Bosh Platinum 6200s at .035

I have the following on my shelf:

Accel 378
NGK WR5
motorcraft BSF42C
BOSCH DR10BC
Champion RF14YC, RF11YC (parts dealer lists RF18YC as well, but I´m sceptical)
AC/delco R83TS (just to add to the collection)

in the ´States, there are a couple more available, especially when you´re fancy for the up-and-comin materials like platinum or iridium.
Can´t check over here anymore, cause the local Bosch dealers just dropped all plugs suitable for Fords smallblock V8s and sixes from their line.

...the 44/45/46 series all fit, 44 being hottest and 46 being coldest. not sure what to do if 46 is not cold enough.

Other way around, 46 is hottest.

AFAIK,
NGK is the only plug maker that goes higher numbers with colder plugs.

huh? damn, been misled by my napa parts man. guess i'll have to watch the 46's and see if they show signs of trouble. got about 500 miles on' em since i got the dsII and MSD working, pulled 'em a couple times and they looks fine. but, i have had to back off on initial timing due to some 'rattling' at mid-rpm's with light throttle/high vacuum, think that could be contributing?
