    OK, so I assume the graphite gaskets will be compatible with the iron heads?

      They are compatable, but will give you a high quench (not optimal) for the iron heads.

      Are we still siscussing an iron head 3400 here? IMO, it's a waste of time, you can mod a 3400 oil pan to work in your car and have all the benifits of the 3x00 shortblock, heads and intakes.

      Wasn't it you who was opting to do a 4 bolt main 60 degree? Why not use a 3x00 block and have the cross-bolted mains that use the oil pan as a girdle?

        ROL makes graphite headgaskets for the 3.4 iron head engine.. .040-.045" compressed thickness.

          Yes, we are still discussing my building a 3400 hybrid. 3400 bottom end with 2.8 heads. Maybe a waste of time, and it may be better to use an all 3400 engie, but then how would I be able to fit a carb? Again, FI may be better & I may be able to get more power, but thats not the way I'm going with this build. Keepin it 'ol skool, ya know?
          If I was going strictly for balls out power & not worry about hacking the firewall, I would probably go for a S/C 3800 or a 4.9 v8. But its not like that. Just as my sig. line said, tuning a car is fully of compromises & while I want something really ballsy, that really packs a punch, I am perfectly willing to lose a little power in favor of keeping a "clean" true school appearance.

          I dont remember posting about wanting a 4 bolt main, but as my friend showed me, the 3400 uses the pan as a girdle stock so thats a point in its favor. Since whatever I get will have a rebuild anyways, it just makes sense to go ahead & cross drill for much better oiling.

            using the iron heads on a 3400 block will net about a 50 HP loss.. or more.


            People have used the aluminium top end with a carb before, If you have enough hood clearance you could always weld a carb flange ontop of a 3400 UIM and block off the TB neck.

              Dave, a side draft carb would be a better idea, then an adapter would just be needed to mate it to the upper manifold (based on the availability of a carb big enough).

              X 11, I had you confused with another member here with an X11, who is running a 3.4/3400 hybrid motor with boost, sorry.

                  Dave, How do you come up with that power loss figure? I could see it if someone used iron heads with alum. pistons, but not if built properly. Seriously, does the 94-96 camaro's make LESS power than say, a venture mini-van? I cant see that.

                  Hood clearance is not an issue as I plan on cutting the hood scoop & raising it. I've never heard of anyone cutting a UIM to mount a carb. Got any pics of how to do this? So far everyones said that this process simply cannot be done.....

                    Yes, they make less power (http://60degreev6.com/content/60%C2%BAV6_Family_Tree)
