30-35 lbs is about correct for a 3500 lb car with a mild 327, less weight won,t get the car smoothly launched, and may be a P.I.T.a. on the street
flywheels less than 25 lbs are best used on cars that weight under 3000 lbs

every choice you make is a compromise
heavier flywheels reduce the engines ability to accelerate the car but tend too reduce wear on the bearings and allow the car to accelerate smoothly at lower rpms, if you will almost always keep engine rpms over about 3500 rpm, a lighter 20-25 lb flywheel makes sense, if you frequently run the car in the 1200 rpm-3300 rpm range the slightly heavier flywheel makes driving easier
IF YOU CAN,T SMOKE THE TIRES AT WILL,FROM A 60 MPH ROLLING START YOUR ENGINE NEEDS MORE WORK!!"!
IF YOU CAN , YOU NEED BETTER TIRES AND YOUR SUSPENSION NEEDS MORE WORK!!
