Hey all was looking at a 68 GS convert with wrong Engine
do you think its still worth buying tp put a 400 back in one day?

 

Let's see: https://myclassicgarage.com/marketpl.../1968-buick-gs. Seems those came with a 350CID also, no mention what the existing motor is? May be a better swap than going back, could probably keep also looking cosmetically stock with underlying performance upgrades. Perhaps headers, retain stock or add "400" air intake.

I'd do something as install a factory look tri-carb setup, keeping in context with GM Pontiac. Way more wow factor when popping hood.
