Motor is a straight swap using all your existing parts;
you just need the 350 specific parts like the 350 memcal ( chip with tune on it ) , injectors and a 350 knock sensor

Would be worth at least taking the heads and pan off the 350 to check the condition.
There are 150K engines that have had a easyt life and others that are near dead

 

IMO it's important to have an overall goal of what you want in the end. The costs can increase quite a bit depending on the power you want to end up with. If you don't plan it out you can also end up with unexpected costs and/or an unfinished project.
