340 intake I am not familiar with

They are a nice intake. I put 1 on my old 72. 340 swinger and gained 1/10 in the quarter mile. I needed to run an adaptor plate to use myTQ carb.

Had the 284/484 cam and Casler headers. As far as I know it is still on the car. It has been sitting inside under a tarp ever since I sold the car long ago. Kim
