Why this part
A flexplate spinning at high RPM under load is not the place to cut costs. Aeroflow's SFI certification means this unit has passed independent burst-strength testing, not just a manufacturer's own spec sheet. For anyone running a 350 SBC at the track, that certification is often mandatory — and always worth having.
