Aluminium Flywheels

heres my 2 cents think about this a nissan maxima from the 90s wieghs in at about 3800 lbs some heavyer with options. the flywheel is smaller in diamitor and lighter then a mopar around nine inches is my guess. those engine curtainly have less torque the a 340 or 360 and work fine from stop light to stop light. mopar put these heavy fly wheels in for driving comfort not for a performance gain on the street. so grandma could drive it to the grocery store with a smile and helps run smooooooth. engines like 340s are curtainly not a race engine straight off the showroom floor though they tend to kick chevy butt all day. the stock flywheel is a street compromise like only 10/5 compression 3.23 gears weak springs and shocks smooth idling cams.
(witch also helped with federal emisions). so if your willing to drive around with a lopey cam then your probley ready for a alumanim flywheel small compromise that will gain you every time you go to smoke a crapy chivy
