I'm building a 572 B1 motor for a buddy. Callies 4.5" crank, World aluminum block, B1s fully ported.

It will be a pump gas motor and then spay it 350-500, Drag Week car

Trying to decide between the Manley Pro I-beams and the Oliver I-beams. Both with ARP625 bolts.

7.100 2.200 and Chrysler width

Both are rated for over 1,000 HP.

Hoping to make 900-950 on the motor and then spray it to 1,300hp

Does anyone have any experience with those and have any opinions on either one?
