Check it out, print one off, keep it in your wallet for whatever reason you will ever need it.

also, check out my new odds'n'ends page for a bunch of useful info that im putting together. if there is sumthing that you think should be added, let me know.

 

There was no 3.8 in thirdgens

 

then what did the 89 TTA have in it?

 

You forgot the '83 LL1 HO 2.8 VIN code L (Firebird SE only).

'82 LU5 - 7
'83 LU5 - S
'83 L69 - 7

 

in the pontiac book i have, it doesnt show a letter 'S' for any motor in 83. same with the number '7' for 83.

 

What book do you have?

 

It's an original F-Body Pontiac Illustrations Manual straight from the shelf of a bankrupt Pontiac dealership.

 

That's a big book...

 

You should see all kinds of references in there. Look up any engine part or look in the Illustration section 0.000.

'82 5.0-7 is the LU5
'83 5.0-S is the LU5
'83 5.0-7 is the L69
'84 5.0-G is the L69

 

im lookin in section 0.000 and still no '7' or 'S'. Plus in the pages where it decodes the VIN's, it still has no 'S' in 1983 or no '7' in 1983.

 

btw, what are yur sources?

 

Look at:

82-90 Illustrations section 0.000 page 0-37

1982-83 "F" ENGINE ASM-5.0L V8 (LU5/5.0-7 & 5.0-S)

0.000 page 0-35

1982-'86 "F" ENGINE ASM-5.0L V8 (LG4/305H, LU5/5.0-7 & 5.0S, L69/305-7 & 305G)

Look up any engine part#
For '83 when in refers to 5.0-S, "S" = LU5 and 5.0-7 = L69

As far as references:

'82-'83 P&I
'82-"84 P&I
'82-'85 P&I
'82-'90 P&I
'82-'91 P&I
'82-'92 P&I


'82, '83, '84... Dealers Albums, Brochures, order forms ....etc, for a few.

 

that's weird cuz it shows it under the illustration but it doesnt show up in the VIN breakdowns in the front of the book on page 5.

 

That is one bad thing about the later books that cover most to all of the third gens, a lot of info is missing. That is why I have individual year editions and 2-3 year editions. They have the correct breakdowns in the front.

 

it was published in 92, thats not that new

 

Just one, LC2. Not your average V6

 

'92 was the last year it was published for the third gens. I should have added the '82-'92 book has a lot of info from the "earlier years" missing.

 

guess that explains it

 

No L98?

And yes, in '83, the L69's number was a 7... i know, i have one.

 

L98 is the 5th one down....

 

I stand corrected. The 3.8 in the TTA didn't even cross my mind
