I have never had a "A" CJ intake, but I did used to a pair of the C8AE-J early CJ heads.
Werby, don`t forget that the 68 1/2 CJ Mustang Hot Rod tested was probably 300 pounds lighter than a typical 69 or 70 Mach 1. I seem to recall that test car was a light pre production car, around 3200 lbs. By comparison, my 69 Mach 1 R code auto weighed 3560lbs, and my 4 speed 70 was 3620. Both my cars did have PS, PDB, and fold down rear seats, but they also both had aluminum intake manifolds, and the 70 had headers too. Neither had A/C. And one of my 69 Cobra fastbacks was over 3800 lbs, all weighed without driver.
