Keep in mind that no matter what site you go to, or what lists or reading material you invest in at least 30% of it will be wrong. There is NO SUBSTITUTE for a Caliper or Micrometer(and an engine that is torn down and in measurable parts) when looking for an FE to build on. I can't tell you how many people call me each month wanting to know why their 427 Block has no
Oil Relief Valve hole in it(390), or HP cast into it(360) or 'P'(352) or no Crossbolts(332) or yadayadayada 'like all the pictures' when the guy told them it was a Side Oiler. If it is too good to be true, it probably is. Spend accordingly. Just some advice. Dennis, DSC
