'73 Intake length

Would someone have the length of the intake from the head flange to the top of the velocity stack airbox sealing flange? I misplaced mine and am replacing them with throttle bodies but want to retain the stock airbox. Thanks.

The original was MFI but I am changing to EFI throttle bodies.

Base of the MFI throttle body flange to the top of the stacks = 24cm by my tape measure.

Good luck with the fit!

Thanks! Now I only have to decide how high to put the throttle bodies which is pretty much decided by the taper angle from the bottom of the throttle body to the port. I will have 6 identical risers with 4 angled plus 2 straight velocity stacks. Looks like the original stacks were designed for 7000 RPM peak power.
