Where in the VIN is the Engine Code?

Hi Group! My son is replacing the alternator on my '84 T/A T-Top, 305 V-8, but he needs the engine code (G or H) so he gets the right replacement. I am unable to locate my Chilton's (I know it would tell me what position
the code is at). Thanks in advance for the help!

The engine code should be the 8th digit in the VIN.

Vin H is the LG4 4bbl Q-jet
Vin G is the H/O 4bbl
funny how H doesnt stand for H/O?

'Preciate you guys answering my questions before I asked them. Some of the sites I pulled up don't have all the codes in the examples and I couldn't find 'em. This is my 3rd Firebird and I think I'll do a few mods on it. First one was a '90 Formula and it got totalled from behind sitting at a red light. Second was a '95 and it started venting exhaust in the engine compartment... doesn't take long to reach the passenger compartment. It had a few other problems and I decided 170k+ was enough miles for it. Anyway got this '99 second hand and wanted to ID what was in it from the factory and then see what was already modded on it. Didn't want to get an nice new 58mm LS1 throttle body and find I'm pulling off a 58mm LS1..... or an LT1! CAGS was the first thing to go. Scared hell out of me the first time the tranny wouldn't go where I wanted it to! Place I go didn't even charge me for the resistor. Free ram air mod whilst I look at the different air boxes and lids. Think I already have the K & N filter in there but need to see if that mod has already been done. Short throw shifter; B & M Ripper? Probably throw a short stick in it in the meantime. Crankcase vent, maybe K & N dunno. Not all that sure this is the original engine anyway: 2G2FV22G8X2220615
In any case I'll be in here asking questions from time to time....

Good way to tell the VIN H and VIN G without looking at the VIN is by noting the radiator fan. If it is belt driven its the LG4. Electric means its the HO. Belt driven and has two TBI units on the intake manifold means its the infamous CrossFire garbage(not available in '84.)
