Anyone here use total seal gapless rings on a 3800 rebuild? They have 3 sets available.
Total Seal #'s for stock replacement type pistons

MX6684- steel gapless top ring, conventional 2nd

X6684- conventional steel top ring, gapless 2nd

CR6684- ductile iron plasma moly top ring, conventional 2nd

available in std., .020, .030, .040

Anyone have any thoughts which would be better for a DD turbo 400+- WHP build? gapless top or second? I was going to just hone and rering/bearing my block before reassembling it. Possibly have the lower end balanced. (any point to doing that with all stock bottom end components or are they balanced at the factory?)
 


Not sure on the rings, but you will need a machine shop to line bore the bottom end or you will be on borrowed time on the new build. These motors are sensitive to this area and often come apart after something like this. Best bet would be to let the machine shop assemble the entire bottom end.
 
That was the plan. I'm either leaving it completely alone like so many ppl have told me to do, or sending it to a shop to have them do hone, linebore, balance and bearing replacement. Everyone says leave it alone, but it is hard for me to have a 150k mile motor out of the car and basically down to the rotating assy and not have it freshened up when I am putting substantially more HP through it.
