Such junk castings from 2012 are still going strong and getting abused. whistling

Not that any of it matters. Ive looked at some of the stuff you have done on fabo. I should probably look on fabo but did you ever plug and re drill for offset pushrods/rockers?



I’ve done it an recommend not doing it. The pinch isn’t the problem. Edelbrock or Speedmaster heads can and will flow over 330cfm with a 2.08 valve without moving the pinch. Stock rocker offset.
