Verrrrry cool. I always liked the old W motors.

".... 1200 mile r/t in 1 day...." Makes for a long day don't it

I'm going to guess it's a 348.....it's been a long time but it seems like the 348 intakes (and they didn't make a Tri-Power 409) didn't work on the 409s due to port mis-match. The work around was to swap the 409 heads for 348 heads to run the Tri Power, but but gave up port (and valve?) size.
