Daryl,
Yes, I'm using Total Seal gapless rings on my 3.2L engine in my 240. Even
though they're expensive, I'd highly recommend them. I've been running my
engine HARD for the last 3 years and my compression level is still good on all
cylinders (140-150psi). They take a little patience to get them set up
perfect, filing, measuring, filing, measuring, but I do think they increase
compression and performance. I think I paid $130 for the set.
Top End Performance (who I bought mine from) uses them on their crazy 4-500hp
turbo L series engines. So they can take a little abuse.
