Help! Need distance eng to hood 69 Camaro

[Randall Klein]

Winter project: 69 Camaro with SS hood in GT class

283 245HP dual 4's

Need to know distance (room) from head ports to hood (w/scoop)

Gonna try a custom small tunnel ram for the dual WCFB's, and I don't want to lower engine

Any help out there

Yes, I could measure but 500CI big block curently in the way and I'm kinda lazy

Thanks in advance
