My v6 club cab 1998 Dakota weighed 4000 lbs

I swapped in a 383 stroked to 438 with aluminum heads, intake, water pump/housing and a TKO-600. Truck weighed 4200 lbs. or, the same as a V8 club cab Dakota.

The big block doesn't add much weight when you use aluminum parts.

Strip duty? Use the lightest springs you can find. Otherwise, swap in some stock v8 springs, cut 1/4-1/2 of a coil off which will both lower it and stiffen the overall spring a little bit.
