Hello rodders, builders and whomever might be reading this post, It seems to be difficult to find much research on the Edelbrock C4B intake. What's the real scoop on this? When was it initially designed? I'm trying to keep every part 1966 on back because that's what I want to do. After hearing the design was influenced by the Z28 (which was a later deal), I'm starting to think I bought a mid '70s aluminum intake....am I better off to sell it and buy one that would've been used on a 283 back in the mid '60s at the drag strip? If so, what was typically run at the strip? This is a super broad question...I'm hoping some of you who did race back then or did go to the drags in the mid '60s can help me out. Thank you!
