72 Chevelle SS 454 VIN?

[carpoor]

As other have said before, H as the 5th character of the VIN = 350 2bbl. Believe what you want, but people do forge phony build sheets, trim tags, etc for these cars. My ex's father bought a supposed 70' LS6 convertible, everything seemed to check out. He continued to look the car over after taking delivery. Eventually figured out someone had done a great clone from a 307 Malibu. Luckily he caught it pretty quick and was able to solve the issue with legal action.

Buyer beware this day and age...
