I'm looking at a car that could have been a big block at one time. Any tipoffs as what to look for?

Options info '68
I've looked all over the net for the location of the options tag on a '68. I've found all the option codes online just can't find the tag on the car.
I'm new to C3's, sorry.
Thanks for helping an old guy.

If it's a small block, locate the partial VIN# on the front pad right above the water pump. If it matches your cars Vin, then it's an original SB.
The engine isn't original so no help there.
Usually BB had 7 leaf springs; small block had 9 leafs.
I'll be under it tomorrow so I'll take a look.
Thanks for the help.

The closest you'll get to an options tag is a sheet of paper stuck to the top of the gas tank. Occasionally they're still in readable shape.

Hi,
I've always thought that in the 68 model year the only cars with the 7 leaf springs were cars equiped with the optional F-41 suspension. I believe that both sb and bb cars had 9 leaf springs as standard equipment.
Regards,
Alan

What about the 'yellow' and 'red' line points on the tachometer? Were those values unique for big block engines? If so, that could help the poster determine what the car was originally built with.

Hi
If there is only 1 fuel line ( no return line ), then it was a BB as well.
Only BB run the Holleys.
Except for the 390 HP BB version, had 2 fuel lines.
As far as I know, no SB had only 1 fuel line.

Looks nice! post some more pics. Looks like you got one of those rare coupes! (Check the numbers, coupes are relatively rare for 68)
