92 corsica going to buy a 260H by comp. will work fine with the computer right? thats the 1 st question. 2. someone told me to put pistions from a 3100 into my 3.1L to raise compression can i do this without any mods. i just change the rods with the 3.1L's or just leave them? and this will also be ok with the computer 2? or should i just do something else to raise compression. please much help will be very grateful i'm suprised u guys have not killed me yet with all my ????s

that would lower your compression, the 3100 motors have large dishes in the pistons to make up for the small volume in the heads (when compared to the iron heads)

92 Corsica has aluminum heads.... Therefore the 3100 pistons would raise compression to that of a 3100, or 9.5:1.

The Corsica has a gen2 aluminum head engine, so YES, the 3100 pistons can be used to raise the compression. I wouldn' use used pistons. You can get new ones for a reasonable price. If you do go with used ones, you must use the rods they come on, as it is hard to press the old ones off without damaging the pistons. The 3.1 and 3100 rods are the same, so this isn't an issue.

It depends on how high you want to go with the compression. Using the thinner iron head Camaro 3.1 headgasket will bump the compression ratio about 1/2 point. Using the 3.1 iron head pistons will take it up to around 12:1. Note: you CANNOT use the thinner headgasket AND the 3100 pistons, as clearance is too tight.
