Al 69.5 six pack cars and some early 70s six pack cars has edelbrock intakes. The later cars had iron intakes made by Chrysler
I thought it was the other way around. Chrysler couldn't keep up with production with the Iron intakes, and farmed out the work to Edelbrock. This is what I thought happened on the 340 6-packs for the AAR's and TA's. JOE
