80e flexplate with crank spacer, depending on what converter you're gonna run, modify cooler lines, you will have to add a little length to your crossmember for the mount or do a custom one, make sure you have a long tail th350 too, anything else just feel free to rack my brain

 

what setup are you running in your truck ??? .....I what to run a TCI 3200-3500 StreetFighter stall or another brand with a 3200-3500 stall.......B&M stealth pro ratchet shifter......Ok so i would need a 4l80e flexplate and do you have a part number for crank spacer ? the cool lines are easy to do...... what are you talking about here ? you will have to add a little length to your crossmember for the mount ? i have built short tail th350 that i want to use..........can you take pics of your transmission crossmember...LMK...THANKS
