Complete Muncie rebuild, rearend rebuilt and a Yukon Locker added. The 389 is now a 400 with forged rods / pistons, Edelbrock Heads, Butler / Comp. custom grind cam, roller lifters & rockers, customized performer rpm intake and Holley Sniper EFI system. Not to mention the QA1 suspension and 4-wheel disc brakes.
Factory cast iron on the right, Brand New Performer RPM on the left.
First the water passage gets a divorce.
The engineers in 66 did not anticipate long tube headers, which just makes for so much fun these days!
It was a little tricky getting the fit correct without scratching any of the beautiful Pontiac silver blue metallic engine paint.
Whew, it fits, well mostly, factory oil filter location might be a slight problem. But that's ok, more customization.
Wow did not expect that such a light transmission would be such a pain to install.
But the long tube ceramic coated headers sure are beautiful.
