Good article on basic stroker theory

They will make as much power and torque with less stress in the engine with the right parts, cams, intakes, heads, pistons. The difference between the two engines is the amount of stress and friction thats created. The way that I see it is the less stress and friction that a engine and parts have the faster the engine will be.
I've seen a guy that I built a engine for that was a 468 chevy that runs 5.27 in the 1/8 and after 2 seasons he went to a 555ci engine and runs only .08 faster, the difference between the 2 engines is the 468 used std. production iron heads and steel shim gaskets, and the 555 engine uses a stroker crank and aluminum heads with a big roller cam. Seems to me he spent alot of money for .08, something like $40,000.00 more. I would have expected alot more than .08 for $40,000.00 and 87 more CIs.
But like you said (quote) but what do I know.
