Great truck! I also own a 73' 620, and have a heap of questions for you. I would send you a personal message, but I'm new to this forum and I don't know how to.
1. How did you go about building the L16, and where did you buy the replacement parts?
2. Where did you buy your L20 and how much more power does it offer over your built L16?
3. I'm faced with a decision. Swap in a mild KA24 out of a hardbody and have all the power i need (with EFI nonetheless) or put in an L20 and Build the s*** out of it. I just don't know what to do with my truck...
I really like what you have done to your 620, and any help would be appreciated!

Hi Trev,
Sorry about not seeing this sooner.
I rebuilt my L16 while it was in my truck. I purchased most parts from Rockauto.
The L20 was given to me by a freind who I did a favor for in the past. I gained quite a bit more torque and a little bit more HP at the rear wheels. I recommend the L20 over the L16.
If you have a choice...get the KA and don't waste your time on the L20.
I hope that helps.
Aaron
