I was looking at www.carsinbarns.com and noticed on the mustangs and other cars that some of them were A codes... or D codes.. or R codes. and i have always wondered what these codes mean.

Thanks

 

If im not mistaking, its the body style. Like the 70 chevelle/nova/buick are all B bodies. But im not really positive on this though. Maybe someone else can ring in with the correct answer.

 

Bummer I thought it was witch plant they were born in

 

More like option packages.
X engine with X tranny with X Options
ie: 351 Cleveland 4V with 4Speed, with Shaker Hood = Some Code

 

An R code Mustang was 427 8V Hi-Per.

A D Mustang was a 289 4 barrel on Reg gas

An A code Mustang wa sa 289 4v Premium Gas

Q code was a 428CJ 4v.

 

K-code 289 Hi-PO 271hp

 

Alright guys this sounds like a stupid question to me but when they say like a 4v or the 8v they do mean like 4 valves per cyliinder or what? I know what they mean on newer cars but the older cars have always made me wonder, I think it might have something to do with the carb so I was wondering if someone could clear me up on it. yes I know what 2 barrel and 4 barrel and all that mean but its the 2v, 4v, 8v, that have me stumped, I would of thought the numbr of valves but an 8 vlave per head motor, that dont sound right to me.

 

2v = Venturi's
4v= 4 Venturi's.
6V= venturi's from 3 Duece Carbs otherwise known as a Six-Pack
8V= 8 Venturi's from 2 Dual Quad carbs

 

On the older cars it ment that if it was labeled 4v it had a 4 barrel intake and 8v was 2 4 barrel carb. . . what i wouldn't to get a hold of an 8V 427. . . but anyway for the 351 cleveland it meant the valve size to, if it was a 4v it had a 4 barrel carb and larger valves (intake valve was 2.19" compared to the 2v size of 2.05")

 

Thanks guys for clearing it up. I didnt know if i was on the right track or not. Now i have a new wrinkle on the brain .

 

Have a couple shots of vodka, it will iron that wrinkle right out.

 

If you find one thats a KK code, let me know asap.

 

Alright I kinda thought so I just needed a little better explanation, thanks.
