HELP IDENTIFING TRI-POWER INTAKE MANIFOLD

[CONVERTIBLEMAN]

I HAVE HAD THIS INTAKE FOR ABOUT 30 YEARS, I DON'T REMEMBER OR MAY NOT HAVE EVER KNOWN WHAT IT WAS OFF OF, OR WHAT YEARS IT WILL FIT. I SEEM TO REMEMBER BEING TOLD THEIR IS A DIFFERENCE IN HEADS SOMEWHERE AROUND 1964. THE CASTING NUMBER IS "8778818" AS BEST AS I CAN READ IT, ALSO HAS "D245" CAST BEHIND THIS NUMBER, IS THIS A DATE CODE?

The D245 is the date code. D= April, 245= 24th, 1965. So it looks like you have a 65 intake.

The heads were changed in 1965.
