Define the Cobrajet and a non Cobrajet diffrences please
Although others already pointed out there is no 66 CJ, I can tell you the difference between any 428 non-CJ and any 428 CJ
To simplify
"What's the diffrence physically between a 66 428 4V premium fuel CJ, and a regular 428 4V Premium fuel non CJ engine."
ALL CJs had better heads, a 390 GT cam, a much better iron intake, a Holley 735, and freer flowing manifolds. They claim some block differences, but its not constant, everything else above is
Thats the 1st level of the answer
The second level is
Then what is now called an SCJ, but back then was just a drag pack option for lower gears that gave you more goodies was:
- SAME induction, heads, valvetrain, block, etc. BUT add capscrew rods, and a different crank and balancing to match the rods. Techically an SCJ should be slower due to rotating weight increase. There is no extra power on the SCJ, just durability (and thats even questionable)
The CJ and SCJ were not that wild, they just worked. Better heads, a Holley 735 vac sec, better advance curve, better intake, and a 270/280 degree cam, nothing fancy, just all well matched
