Re: Gen 3 or gen 4

Gen 3's are easier to find and cheaper and easier to tune. Also no AFM to deal with. That being said, a lot of the Gen 4's are aluminum blocks so you get a weight savings. Gen 4's also have a nice small PCM, so no big bulky computer and TAC module like a Gen 3. We put a Gen 4 5.3 in my dad's 64 and it was pretty easy. We're putting a Gen 3 6.0 in my 68 and it's not hard either.

Overall, I think the Gen 3's are more user-friendly and are my preference.

As far as DBC and DBW, I think it's more user-preference. DBC can be hooked up to your stock linkage and throttle pedal setup and gives you a better "feel" whereas DBW requires a throttle pedal swap.
