Usually a 3.905" bore is decent on strength and can handle a fair amount. I wouldn't however go with a 3.908" bore. Remember when running boost, your cyl pressures go up quite a bit....In my personal opinion I wouldn't chance it. There are way to many other options available to push your luck with an overbored motor. Just get another stock block and use it on a 3.905" bore....Is it worth chancing? lol

.003 over 3.905 isn't exactly a lot of material. 3.908 should be fine. Usually, you'll take an old ls1 and hone it to 3.903 or 3.905 for new pistons. If you have to oversize again, you can still do 3.908 safely. At that point, you've gone to .010 over and shouldn't oversize again.

Been looking at these DIY truck manifold set-up's doesn't look that difficult and seems to end up being cheaper. May end up looking into something like that.
