Engine idea for the Panel Delivery project

Hey guys I know I havent posted in awhile, but I was just sitting here thinking and had a wonderful idea. Originally I said I had got that 307 for free and was going to stick it in the Panel Delivery. Well I can get my hands on an old inline six out of about a 1950 Chevy pick up that has been cobbled into a wrecker. Any thoughts on this plan, I figure it will be alot easier to bolt in as well and I will be able to keep it a little more vintage looking. Here is a pic, to remind you of the Panel.

 

307 Olds or chevy? I guess it really doesn't matter. If the truck motor is in good shape, I'd opt for it.

 

307 Chevy.

 

what year is that?

 

The panel delivery is about a 1940, havent found the exact year yet.

 

Run the 307...there's enough Stovebolts scattered all over the nation's highways already!
