Crank

[TraviepooCmro]

Does any company do any aftermarket cranks or stroker kits for a 3.4? probably notm, but its worth an ask

The 3.4L V6 is a bored and stroked 2.8L V6. Can't do much more with it.

the 3.4 is about the limit on the 60 degree v6's. all you can do is power adder to get much out of it.

It's made out of the same stuff as the LT1 crank. There fairly strong.
You will have to put up some big $ to have a custom one made.

you could have your crank ofset ground toa 1.8" small journal (its a standard acura SJ dimension)and have a rod costom made for the size and gain a few more cubes, but you will most likely have to have the block clearanced, as stated above there isnt much room to have a longer throw
