Spark plug recemondation

Gentlemen,
I the new guy with 40+ yesrs Mopar experience....273 hipo, 318LA, 340, 360, 383, 426 wedge snc hemi and 440-6
Ive always used Champion plugs....in the LA engines all use a 3/4" reach (thread length ) and heat range determined by the cam, compression ratio, spark advance characteristics, final drive ratio, etc.
The original 340 (1968 vintage) had 2 different cams...4 speed engine had a more radical cam ftom the auto engine but both used Champion N-10Y. For street use i liked N-11Y.
In my opinion, stay with Champion but alot of guys like NGK or Autolite.....or....AC's.....of a equal heat range and characteristics.
Btw....alot of NOS plugs are available on the internet (EBay) or even NOS Mopar.....reasonably priced.
In my present ride, 1970 GTX RS33V0A****** 4 speed car, one of 350 cars made...i use Champion UJ-11G plugs fired by a Prestolite dual point distributor. The engine has 11.0:1 compression ratio with Dana 4.10. N96 air grabber
I'm searching for a 1965 Barracuda Formula S.......273/235 hp engine 10.5 compression.....as original as possible.....no 6's with transplanted engines.....
Regards,
Bob Renton
