318 Engine issue – Vacuum leak?

Hi Team,

Happy New Year to all.

Need some assistance with engine issue with the 318 in my 68 Polara.

Got it idling nicely but as soon as I put it into gear (727 Auto) it dies. I'm assuming this is a vacuum leak? It's a stock 318 with Edelbrock 4bbl intake a Edelbrock carb. Any assistance on where I should start looking for the issue?

Thanks in advance.
