4.6 2v swapping on 4v heads

Best so far is 9.7 @ 146 in a miserable 7000ft DA on the old blower. I was around 900rwhp or so

Basic rule of thumb for these motors is do NOT "convert" your 2V to a 4V. The cost is going to be much higher to do than simply sourcing out a used complete 4V longblock.

@Michael sommers , just to give you some perspective on just how cheap 4v engines can be purchsed for these days, I paid $200 for a low-mileage 4v pullout from a Mark VIII. For $150 more and a day's worth of work I could've pulled one out of an Aviator.

Wow that is very cheap, I just really want a brand new, fresh engine, and I also want to experience an engine build and be able to say i built my engine.
