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. | | MFG | ITEM | PN | PRICE | | ARP | Head bolts | 134-3601 | $60 | | Clevite | Main bearings | MS909P | 24 | | | Rod bearings | CB663H | 24 | | | Cam bearings | SH2905 | 18 | | Cloyes | Timing chain | 9-1100 | 32 | | Cometic | Head gaskets | C5877-040 | 86 | | Comp Cams | Camshaft | Custom | 166 | | | Lifters | 833-16 | 90 | | | Pushrods | 7993-16 | 130 | | Crane | Rockers | N/A | 0 | | Eagle | Connecting rods | 5700BPLW | 236 | | Edelbrock | Intake manifold | N/A | 0 | | Fel-Pro | Intake gasket | 1405 | 19 | | | Oil pan gasket | 1818 | 15 | | Melling | Oil pump | M55HV | 28 | | Moroso | Oil pan | 20191 | 196 | | Professional Products | Harmonic balancer | 8000 | 40 | | Proform | Timing cover | 66666 | 60 | | Speed-Pro | Pistons | L2256F30 | 280 | | | Rings | R9343.035 | 116 | | World Products | Heads | 014150-3 | 1,171 | | Factory | Block | N/A | 50 | | | Production steel crank | N/A | 100 | | | Z/28 carburetor | N/A | On hand | | | Parts Total | | $2,941 | | MACHINE WORK BY SAM | | OPERATION | PRICE | OPERATION | PRICE | | Bore/hone | $225 | Deck resurface | $100 | | Align hone | 125 | Balancing | 75 | | Turn crank | 65 | Head/intake porting | 400 | | | Machine Work Total | | $990 | | | GRAND TOTAL | | $3,931 |
