Flexplate and harmonic dampener with it. Tho I think they will need to be replaced with SFI rated stuff under 10.99 or something. Was thinking about stroking it but with the rods and pistons I have that's not an option. Now I'm looking into either a halo girdle or pan rail girdle. I wanna get the pan rail and spray this thing to the moon, but $1000 for girdle and $2-300 just to have my pan modified(+price of pan) has me thinking. But gotta pay to play, so I might try the pan mod myself, or bite the bullet. I want to see all the butt hurt Chevy guys at the track when I blow by them with my olds 355!!
