why not a short 6.135 rod BIG BLOCK 496?

I get this question frequently from guys wanting to keep cost down in building a stroker 454 BIG BLOCK CHEVY engine, especially once they realize that its about the same as building a big block version of the 350-to-383 SMALL BLOCK stroker concept,and because they want to keep cost down,they want to reuse as many stock 454 components as they can, but the fact is that theres several reasons its not usually a good idea,yes adding a 1/4" stroker crank to the stock 4" 454 stroke making it a 4.25" stroke is a fairly effective way to both increase displacement and with the correct pistons increase compression with a smaller piston dome than a 454 with its stock 4" stroke could use.
one of my most common builds is designed for a street driven muscle car and its based on a 10.2:1 compression 489 -496 displacement big block engine, the heads intake and cam choices depend a good deal on the application of course, but a upper engine kit like this, trickflow linked below or one of the brodix combos

While planing the build, you may want to look into an INTERNALLY BALANCED 496 STROKER CRANK AND ROTATING ASSEMBLY, the larger counter weights the 6.385 rods allow generally do allow either crank balance method to be selected, but youll need to swap to a 427 internally balanced damper and flywheel if you use an internally balanced rotating assembly, which at first seems like an additional expense until you find most tracks will only allow SFI certified dampers and flywheels in most serious race classes and a blow proof bell housing so youll be buying new parts in most cases and an internally balanced rotating assembly tends to run smoother and put less strain on rods and bearings
having larger counter weights tends to make it far less expensive to balance a rotating assembly compared to using Mallory metal inserts
but keep in mind rod and rod bolt strength are critical and those BIG BLOCK PISTONS AND RODS tend to be heavy.
(1) first many if not all 3/8" rod bolt stock big block rods are not nearly as strong as the aftermarket 7/16" rod bolt forged 4340 steel rods
(2) next, the aftermarket 6.385" rods with the 7/16" rod bolts tend to both be less expensive that reusing the stock rods (remember the rod reconditioning, re-balancing,new rod bolts and polishing costs money) and give more counter weight to piston skirt clearance, making it much cheaper to balance the rotating assembly and giving you a marginal better rod to stroke ratio
(3) longer rods will use a piston with a shorter deck to pin height which tend to be lighter weight, and the difference in rod length doesn,t weight as much as the weight savings in piston mass.
(4)longer rods tend to have a bit less cylinder wall to piston drag as the thrust angle on the power strokes a bit better, yes its only a degree or so but over hundreds of thousands of revolutions it tends to reduce wear with a longer rod length
(5) but the main factor is that the longer 6.385" rods allow larger crankshaft counter weights that make balancing the rotating assembly easier to do and usually far less expensive
SHOP CAREFULLY THERE ARE COMPLETE BALANCED ROTATING ASSEMBLY'S AVAILABLE
rectangle head ports work best on high rpm combos with high compression (10.5:1 and higher) and cams with over about 250 duration
oval head ports work best onmid rpm combos with under 10:1 compression and cams with under about 240 duration
obviously the piston pin rides higher in a piston with a longer rod
good rods come in several lengths

here is a few other builds, and related, linked info.
info you should read as it provides a good bit of very useful info as to your engine potential
just keep in mind bragging rights on impressive peak horse power might sound good, but having a dependable low maintenance combo that runs decent, and won,t require constant and expensive maintenance and parts replacement, designed to run in the 2500rpm-5000rpm range on the street is FAR more important, on any street driven cars engine.
and if set up in the correct car with decent tires and suspension easily get the car into the low 11 second to mid 10 second range (mostly dependent on weight and traction

While planing the build, you may want to look into an INTERNALLY BALANCED 496 STROKER CRANK AND ROTATING ASSEMBLY, the larger counter weights the 6.385 rods allow generally do allow either crank balance method to be selected, but youll need to swap to a 427 internally balanced damper and flywheel if you use an internally balanced rotating assembly, which at first seems like an additional expense until you find most tracks will only allow SFI certified dampers and flywheels in most serious race classes and a blow proof bell housing so youll be buying new parts in most cases and an internally balanced rotating assembly tends to run smoother and put less strain on rods and bearings
having larger counter weights tends to make it far less expensive to balance a rotating assembly compared to using Mallory metal inserts
but keep in mind rod and rod bolt strength are critical and those BIG BLOCK PISTONS AND RODS tend to be heavy.
(1) first many if not all 3/8" rod bolt stock big block rods are not nearly as strong as the aftermarket 7/16" rod bolt forged 4340 steel rods
(2) next, the aftermarket 6.385" rods with the 7/16" rod bolts tend to both be less expensive that reusing the stock rods (remember the rod reconditioning, re-balancing,new rod bolts and polishing costs money) and give more counter weight to piston skirt clearance, making it much cheaper to balance the rotating assembly and giving you a marginal better rod to stroke ratio
(3) longer rods will use a piston with a shorter deck to pin height which tend to be lighter weight, and the difference in rod length doesn,t weight as much as the weight savings in piston mass.
(4)longer rods tend to have a bit less cylinder wall to piston drag as the thrust angle on the power strokes a bit better, yes its only a degree or so but over hundreds of thousands of revolutions it tends to reduce wear with a longer rod length
(5) but the main factor is that the longer 6.385" rods allow larger crankshaft counter weights that make balancing the rotating assembly easier to do and usually far less expensive
SHOP CAREFULLY THERE ARE COMPLETE BALANCED ROTATING ASSEMBLY'S AVAILABLE
rectangle head ports work best on high rpm combos with high compression (10.5:1 and higher) and cams with over about 250 duration
oval head ports work best onmid rpm combos with under 10:1 compression and cams with under about 240 duration
obviously the piston pin rides higher in a piston with a longer rod
good rods come in several lengths
LATE ONE PIECE SEAL CRANK LEFT, EARLY TWO PIECE REAR SEAL CRANK RIGHT, most aftermarket blocks are designed for early style cranks

here is a few other builds, and related, linked info.
info you should read as it provides a good bit of very useful info as to your engine potential
just keep in mind bragging rights on impressive peak horse power might sound good, but having a dependable low maintenance combo that runs decent, and won,t require constant and expensive maintenance and parts replacement, designed to run in the 2500rpm-5000rpm range on the street is FAR more important, on any street driven cars engine.
and if set up in the correct car with decent tires and suspension easily get the car into the low 11 second to mid 10 second range (mostly dependent on weight and traction
