It's totally in line with the thread. I'm doing a high compression blower motor, others are building up what they want too. The 2V part is what we're most concerned with as that's the crux of this being an easy swap. We try to stay off the 4V discussion much (but 4V guys are totally welcome to come and chat... it's still 5.4 in a stang) just to keep the topic fresh and useful.
Yes, you can punch it out to 6.0L, there's a couple kits on the market but you're getting kinda deep into boring at that point (more on this in a second), and the heads are really maxed out at 5.4L so it really makes the most sense to do 6.0L in a 4V. Still, you'll get a boost out of it in tq production no matter what.
The other downside to doing the poke and punch to 6.0 is that the crank throw and rods are are already pretty long and you'd be stretching it even further to where it affects cylinder longevity as it will tend to exacerbate the issue of cylinder side-wall wear that we deal with anyway thanks to the long rod.
I'd avoid punching it more than .030 over. I hear a lot of reports of heat issues with more than that. Still at 30 over you've got 336cid which is plenty in a high revving engine that can easily break the tires loose in 3rd gear as it sits.
I've got a thread in the classified section for a group purchase for rods and pistons. You'll never get a deal like this on the rods so if you're serious, jump on it while you can. The pistons haven't had any takers so I'm about to pull them from the offerings list.
