| RE: 428 or not? |

You could punch out the freeze plugs, in the center one, on the cylinder wall, it should say 428. Not sure which side of the block its on, maybe both. All 428s, from the standard to the SCJs had 428 in the water jacket. Also, if the engine is out of the car, you could pull off the oil pan and look at the casting numbers on the crank. There should be one of these:
C6ME- '66-'68 428, including early '69 CJ
1U- same as above
1UA- early '69 SCJ
1UB- '69-'70 police, mid '69 CJ
A- late '69 to '70 CJ, (may also have 1UB on #1 counterweight)
B- Late '69 to '70 SCJ, (may also have 1UA on #1 counterweight)
All casting numbers on the #7 counterweight unless otherwise noted. Hope this helps! |
