As much as I want to keep my 68 as original as possible, I have come to the realization that my 1438 ain't what she used to be. It's the original motor, drips a bit, blows a bit (sometimes a little more than a bit) and I'm assuming that after 150k miles, has gotten a little weak. I've thought of having it rebuilt by my buddy/mechanic but it would have to be done in his spare time. The thought of not being able to drive my car during the motor rebuild would suck!
One option he suggested was replacing the 1438 for a rebuilt 2l (carbed) he has in storage. He figures swapping would be a two day/4 cases of beer job
This would allow me the pleasure of driving my Spider while we take the time to rebuild my 1438. Canadan knows how I drive 
and figures once I get the 2l under the hood, I won't want to go back to the 1.4. But will the torque of the 2l have a detrimental effect on my older trans and diff? My other option is to buy more oil and just drive the 1438 until it gets worse, although it doesn't seem to be getting worse.So if I decide to swap, we figure we will need a different trans bell housing and will have to switch to an elec fuel pump. Distributor might also be an issue (no hood bumps). I was wondering if anyone here has done a similar swap in the past? If so, what problems, opps I meant challenges did you encounter?
Making this decision could be a "what did I get myself into" or result in looking back and saying to myself... self, how did I ever drive that car with that small motor?
Thanking you in advance, I appreciate your help.
