I have a 62 Gal. with 352 & a slush-o-matic. I have every thing to convert it to a big input top loader & 389 gears. about 30 years ago I bought a box of goodies from a guy cleaning out a garage & in it was a Lakewood blow proof bell & an alum Harvey flywheel. The flywheel is 184 tooth which means I can use a modern starter Being the cheap bastard I am, I'd like to use it rather than buy a new steel one. My concern is I always thought alum. flywheels were for light weight cars. Any input would be a apr.  Thanks, shady
