    So I have just about all my parts for my bottom end collected; (99 6.0L iron Block, Callies compstar crank 3.625/58x reluctor, forged 4340 6.125 rods/ 12cc dished pistons with wiseco steel wrist pins, 302-3 holley oil pan, arp main studs, BTR Twin turbo stage 3 cam, melling high volume oil pump) and I have a set of 243 heads I will be building aswell. I believe the cr will be 9.8ish. I've decided to go with twin ON3 76mm turbos and cant figure out if I should go with .68 AR or a .96 AR. Also because I cant find what the BTR stage 3 twin turbo cam will rev too. I will be putting a T56 magnum behind it and 4.10 dana 60 rear end aswell. I'm leaning towards a 96 A/R but I just want to be 100% sure. All help is appreciated

    I would go .68 and I'd also rethink the 4.10's
