Chevy 348 Big Block Engine Restoration Stroker Engine Assembly
|
The key ingredient in the stroker assembly is this forged 4340 steel Eagle crank. Its 4-inch stroke is 0.750 greater than the stock 348's 3.25 stroke. Since 348 blocks have more compact crankcase dimensions than 409 blocks, Eagle reduced the counterweight diameter so it drops right into the 348 block with room to spare. The drilled output flange works with manual and automatic transmissions. View Related Article
