I was wondering if amybody has used those gapless piston rings. I need new rings and am debating as to whether to go with stock ones or the gapless type.

Please only reply if you have had personal experience with them,

Thanks,

Dave

By the way these are 502 motors with Whipples.

i use the totalseal rings on most all marine motors i do because i like the way they seal up i get good blowby#s with them also i do not get that oil smell in the boat after you run it hard .but you will get alot of different opinions on them most of the builders i have talked to that did not like them i found did not know how to instail the rings

gapless works well. i measured 2-5% leakdown on my 516
after 3 hard seasons.
