piston quest

[Jim DeShon]

I was not of aware of what Mark just mentioned. What I am really interested in learning is the dementional differences between the 1800 and 2000 motors. The "usual" practice when engine builders stroke an engine is to make the connecting rod shorter and use the same block. This is due to the fact that the crank is closer to the combustion chamber at TDC. In the case of the Fiat motor, when they re-engineered it to make the 2000 motor they apparently made the block taller. That would mean that the rod could be length they wanted. Sometimes engineers change the rod length to get a better rod angle. This is to improve torque. This would be good to know if one wanted to swap some parts around on his own. I've done this a lot with other motors I have modified in the past. ...J.D.

srr aint goin to be able to mesure , the PO agreed to pay me back and get his engine back

[Jim DeShon]

No problem Tappy. I will find that information somewhere. Now you need to snap up one of those Volumex motors to stuff in that car . I can not use a Volumex motor here even if I could find one because of emission regulations. Good luck finding a good motor this time. ...J.D.

here's a foggy picture of the pistons in the replacement engine :
