1984 2.8L V6s: LL1 "CodeL" vs LC1 "Code1" ?
Any good insights or details as to differences (or how to recognize)
these two 2.8L V6s?
All I know or have gathered is (for 84 Firebird):
LC1 "Code1" 8.4:1, 107hp, 145 ft/lbs, R43CTS plugs
LL1 "CodeL" 8.9:1, 125hp, ??? ft/lbs, R42CTS plugs
They can be differentiated by the 8th digit on the VIN but beyond that,
don't know much about their differences, internally or externally...
Why the cooler plugs on the LL1 and would the LC1 benefit from the same plugs. E.g. would that be a better heat range perhaps for
the LC1 as well?
