Ways to increase engine size:
Big Bore kits
Advantages:
Relatively easy
Changing just the cylinder and piston is easier than splitting the cases and installing a stroker crankshaft.
Cheaper than a crank, but not by much.
Disadvantages:
Head is not designed for that diameter cylinder.
Too large bore results in incomplete combustion
Too large bore reduces cooling jacket.
Larger piston adds stress to rod and crank.
Excessive vibration from heavier piston. Still need to remove crank to rebalance for heavier piston assembly. But if you do all that work, you might as well use a stroker crank.
Stroker Cranks
Advantages:
Stock Piston sizes are cheaper to replace and easier to get.
More torque
Better traction
Easier to control
Complete combustion – using head designed for this bore.
Longer stroke breathes “deeper” while valves are open.
Generally, better power than bore kits
Disadvantages:
If done poorly, can result in vibration
Very large stroke may require case modifications
Somewhat more expensive than big-bore kits.
Few companies can do it properly.
Big Bore / Stroker Crank Combinations
Advantages:
Properly done, you get the best power
Overcome design problems with OEM design
Tailor power/reliability to application
Overcomes limitations of just bore or just stroke
Tailored bore/stroke ratio
Adding stoke allows larger bore
Disadvantages:
Costs more
Non-drop-in kits can be more work to install.
Raing Transmission
Advantage
More horsepower
Light weight
Safe for engine braking
Disadvantage
Labor intensive
Costs more[/quote:2ux8vghd]
