That's a cool project TB.I have a '96 Caprice project that I'm slowly trying to convert to an Impala SS clone/hot street/strip/auto x car.If/when you start doing engine mods you should check out
PCMforless.com .It's a company that reprograms the pcm for mods like gear/tire size changes,cam changes,bigger injectors,etc.Has your Dad had any transmission problems yet?My car has had the trans rebuilt twice and lots of fuel pump problems.I hope to completly rebuild the suspension along with lowering springs,aftermarket control arms,sway bars,etc this summer.
