At the risk of sounding like a complete moron [don't know anything about the 3500]can the 3500 pistons be used in a 3.4 ironblock.

Actually, its the opposite, same bore but different stroke (for 2.8 and 3.1 at least)Originally posted by Joseph Upson View PostComment

I only mentioned the 3.5 to 3.1 because they have the same stroke also and without a significant change in some parameter you can't use the pistons but correct the 3.1 has the same bore however as stated the 3.5 to 3.1 differ by bore size.Last edited by Guest; 04-08-2007, 06:26 AM.Comment

I just checked the specs: 3500/94mm and 3.4/92mm bores,don't know piston pin location.I'm wondering if the 3500 pistons could be used in a 3.4 ironblock and what the compression would be ?Comment

Only with the complete rotating assembly because the 3.5 has longer rods than the 3.4 also I'm not sure if the 3.4 block will need clearancing since the rod big end is larger along with the crank pins on the 3.5.Originally posted by ezrollin View Post
And then there is the overbore you would need.Comment

Wrist pin hight has been moved up, according to Whitelighting, also teh longer rod would indicate this to be as well, 5.9" to 5.7" The big end is larger but I don't believe the center point offset would be .2". But that will need to be verified, I don't recall how much larger the rod journals are in the 3500.Last edited by Guest; 04-08-2007, 11:33 AM.Comment

2.248" is the rod journal diameter the bore is 2.375" so there maybe a possibility it will interfere with the 3.4 block rails if they are not already relieved.Last edited by Guest; 04-08-2007, 11:54 AM.Comment

What about the 3500 piston on the 3.4 rod,how much would that drop compression ?Comment
