Here's one for the engine guys. Is it possible to get 518ci out of a passenger 454 BBC. I believe it would take a .030 over piston and a 4.50 in stroker crank. I don't know if it would us the stock 6.135 rods. this is just what i have seen on some site. I also would like to know is it worth it to have that big of a stroke to achieve that cubic inch. Pros and con on the combo. Thanks for any info.
