Lightweight Big Block Chevy Mock Up Block wanted to Borrow

[jbtech]

Looking for a lightweight big block mock up block to check hood clearance in my '67.

I'm using GM '67/'68 Big Block Frame mounts
GM Open air cleaner Drop Base I believe 2"
AC212CW Air Filter
GM Open air cleaner lid + Wingnut

I need to see if my 163 Intake will fit with this setup or I'll try a 569 LS6 intake. The goal is to keep the standard NON-SS Flat Hood although the 163 will outperform the 569. Any input is greatly appreciated.
