6.1 Hemi 69 Barracuda Fastback Father Son Project
Today I went to the shop and punched a 4.5" hole for fresh air for the CAI.
Before... US Car Tool Core Support with no hole.
After... hole punch.
4.5" diameter hole will let air in directly behind the grill.
The US Car Tool Radiator Core Support is about 1/8" thick steel.
My Harbor Freight Hydraulic Punch with a 4.5" Die and Punch set from Amazon did a nice job making a clean round hole. Will most likely use this same hole to pass the front headlight and parking light harness through.
New radiator opening is for a 26" Champion radiator. Original opening only fit a 22" radiator.
Here is what it looked like when we started disassembly... Some of the factory "Blackout" still in tact...
