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.
