hatchsub Posted November 22, 2010 Share Posted November 22, 2010 Im interested in putting the SPFI pistons in a EA81 for a hi compression one. I have all B sized pistons in my engine currently. How and where are the SPFI pistons marked? Quote Link to comment Share on other sites More sharing options...

GLCraig Posted November 25, 2010 Share Posted November 25, 2010 IIRC, on the face of the piston there will be either an A or a B stamped on it, with a diamond outline. Quote Link to comment Share on other sites More sharing options...

Yea thats what i found on my EA81 pistons. They were all B sized. But i guess the EA82 pistons are not marked the same. They have an arrow pointing towards the front of the motor, the word up at the top of the piston and a R (maybe for the right side). This is just the info i was given from the seller. Im not sure what to make of it cause i was told previously that they should be marked A or B as well. Quote Link to comment Share on other sites More sharing options...
TomRhere Posted November 25, 2010 Share Posted November 25, 2010 The 2 EA82 short blocks I have here both have a B and UP on the pistons. One block is a carb model, other is SPFI. Quote Link to comment Share on other sites More sharing options...

I'll try and dig them out this weekend and take a picture. Quote Link to comment Share on other sites More sharing options...

Any luck with the pictures? Im curious what they look like. This way i can get back to the seller and get some pistons and get my build underway.

hatchsub Posted November 28, 2010 Author Share Posted November 28, 2010 Hey Craig thanks a ton. Ill let the seller see this and i can get moving on this thing. Thanks again!. Quote Link to comment Share on other sites More sharing options...
hatchsub Posted November 30, 2010 Author Share Posted November 30, 2010 If they are A sized pistons would they have been stamped or did they only stamp B size pistons? Reason i ask is the pistons i want are not stamped on the right side. Quote Link to comment Share on other sites More sharing options...
