I fitted my 650rwhp street/strip motor with a BCR cap & girdle kit 8 years ago. This engine is still taking the beatings on a regular basis. I did however add bushed lifter bores so oil pressure never drops below 20psi at idle when hot lapping her. This combo hasn't been apart except for some head work in that 8 years. I've built a few strokers before, but none have lasted this long without having an issue to require a rebuild. I put it down to the quality girdle combo & the bushed lifters, money well spent, no junk parts.
