Hi all my van has a 350 chev T700 at the moment and the 350 needs recond but i have a turbo pattern 308 with a T350 so if i just take the T350 off will the 308 bolt straight up to the T700 with the same flex plate?Thanks .(the 350 will go back in when i rebuild the van but just after a quick fix to get it to the van nationals)
