The Recipe
Since you probably don't have a bunch of 30-year-old parts lying around for your next engine build, we admit that your price for this 355 could be a bit higher. To calculate your probable cost to replicate this combination, substitute modern-day equivalents of the recycled parts used in this build. By tacking on $180 for a set of Crane Energizer rockers (PN 11744-16), $200 for an Edelbrock Victor Jr. intake (PN 2975), and $340 for a Holley 650 double-pumper (PN 0-4777C), your cost to duplicate this 355 could come to $4,651. Either way, it's still dirt-cheap.
