318 power?

Big block v small block engine wt & how it affects the car, handling etc.
Percentages gentlemen......
Take a 3500 lb car with a SB that has a 54/46% weight distribution [ pretty typical ], 54 being the front.
That is 1890lbs over the front wheels. You replace the SB with a 100 lb heavier BB. The front end weight has increased by 5.3%.
Is anybody's butt-meter going to feel that? Weight distribution change is even less 55.3/44.7.
