Ok I'm adding the info on the piston dishes for both the FWD cars and the RWD 3.1L's and 3.4L's. I got alot of info from Colin and found a few specs on the net.

Anyone know where there is some real numbers? Or does anyone have some pistons free that they can measure them?

There's some specs on Silvolite replacement pistons, if that's any help...
Of course there could be some minor differences though.

[SappySE107]

the silvolite DOHC pistons are the actual pistons used. not sure on the pushrods.

[geoffinbc]

Ok what I've go so far is
All iron heads
2.8L AL head
3.1L AL head
I need the 3100 3400 and 3500 specs for piston dishes.

Also added the Cumbustion chamber sized for iron and aluminum heads

Sweet its UP!. Looks cool. And everyone will be glad to know their name is on the bottom for credit.

If you have been missed let Me or Brad know.

The pushrods used Mahle pistons from '87 Gen2 UP

[Will'sFiero]

Few things I noticed...

Fieros had iron heads through '88 (and were transverse/FWD of course)

Not clear on what had iron heads '87-'95 (say FWD iron head ends production in both '87 and '96)

Didn't list Gen II head valve sizes

if you mention change in something (valve guide sizes in 2000 for instance), mention new sizes and old sizes

didn't mention bore of 3.4
didn't directly mention stroke of 3.1 or 3.4

"close coupled" cats, not "closed coupled" cats

only see two references to DIS wheels, thought there were three versions?

neutral torque axis engine mount vs torque axis engine mount of early '90's?

what's a P05 controller?

diameter of pin on large pin 3500 crank?

3900 in G6 GTP coming out?

earlier, somebody was commenting on the dearth of a-bodies.
note the sig... I have an a-body, and it is on track to be pretty fast...

Just wanted everyone to know that the tree has been updated on the site. The pictures are there, but the links o the larger versions don't work yet. I should get that done in the next day or 2...

[CJROTHY]

F-bodies went serpentine in '87.

[Will'sFiero]

'06 3900 has 99 bore by 84 stroke. The bores have been moved outward and are no longer centered over the crank.

'06 3500 shares 3900 block, but has 76 mm stroke.

Still looking for rod length

[bszopi]

That depends on which 3500 you are talking about...

The VVT version does share the same block as the 3900, but the standard version has a block still based on the previous 3x00 family.
