Buying My First Muscle Car 1973 Duster 340 Interior Pic

I just got the VIN number from the owner. The title looks good and is under his name. However, I decoded it and it looks like the original car had a 318 in it.
G = 318 150HP(net) or 170HP(net) 1-2BBL 8 CYL

I'm hoping the previous owner dropped a 340 into it but I'm starting to get my hopes up :/

Well with that info that means it's not the original engine and trans unless it's a 318. In that case I'd drop my offer down to 2500-3000 based on the fact it's not a 340.
