3400 bore size and heads

[shrek]

Hey: New to this site but have a few questions about a 3400.I bought a 95 Camaro from a friend that had run hot.while he was tearing down the motor he found a broke head bolt or broke one in process,couldn't get real story.
Anyway have since pulled block and tore down rest of the way.Wondering how far can the 3400 be bored .010,.020,.030 and what would be the recommended last resort to bore to? Has a few places in cyl wall that would
like to clean up but not sure as to how far to go.
Also was wondering as far as the v6 go what parts are interchangable to the
3400. Can find all kinds 3800 in everything and 2.8 as well but very few 3400
Can a 3800 be swapped into this car,if so what would have to be done?
Are there better options as to adding a little performance to what i have withouit breaking the bank? I know this was a few more questions than i started out with but while was here thought would ask some.These v6's are
new to me and this site is great.I just feel like a kid on here because most
everybody seems to have been dealing with these v6 a while.
Thanks Shrek

Well, I'm boring my 3400 .040" over, mostly because it was easy to find pistons and a decent ring pack in that size. That and I get a small bump in static compression ratio.
I have been told you can go as far as .060" over.......

Or if you want, the 3.4 Camaro pistons can be used in conjuction with the 3500 V6 heads (which have a larger combustion chamber aand better flow characteristics) to get around 11.5:1 SCR.

if you have a camaro you have a 3,4 not a 3400 and they can be safely bored out to .060
and any performance parts out for a 2.8-3.1-3.4 camaro is the same .
to get a little bit more compression (if keeping the iron heads) you can use a 3.4 dohc pistons any performance cam comp,crane,edelbrock offer for the 2.8 will work.along with double timing chain ,headers, and more there is alot of stuff out for the gen 1 motors.
but still comes up short to the stock gen3 motors have roller cams,better oiling system,aluminum heads that folw alot better.

3.4 and gen3motors

Thanks for the replys.
I know this may sound funny,but i'm new to these v6's so what is a Generation 3 engine and what type cars are they in? What size engines are they. Also what engines and cars had the aluminum heads?
Thanks Shrek
