how much?

honestly, I'm not sure.....seems I "used" to know all this stuff....but been out of the scene for quite some time now. Before my parents bought the car long ago...someone had put the 340 and hood on it...and maybe a different front suspension...but I really can't remember exactly what was done. I know it's got a 3:91 suregrip in it also, but again, can't remember if the previous owner had it done or not.
I don't mind a little helpfull nitpicking either ;)
