Furthermore....
The guy from the Emissions Lab at the DMV told me that EVERYTHING must be swapped over. Even the gas tank... (if) There is an EVAP monitor on the tank that measures volume and vapor amount. Basically, you have to do a full change-over to the donor vehicle's emission system... even if your vehicle didn't have said systems.

So, these rules make engine choices a little more limited. The LT1 I had originally selected is out of the question since it is from the mid-'90s.

Now I'm considering LS1 or LS2.
Actually, I just found a late model Trailblazer SS drive train with under 20k miles...
But, it's just a little out of budget.

Unfortunately I may have to put the V8 swap on hold for a bit.
I need to prioritize projects. My first concern, as should be with anyone (IMHO) with larger tires... especially if thinking about an engine swap, is to upgrade the brakes.
I'm not happy with the brakes as is, and have heard great things about R1 Concepts. I think I will do this first, then build up money over time to get the unicorn engine that I want... later .
