Hey there... I have a set of 455 exhaust manifolds that I may end up selling. I've had them for quite a while and I can't remember which engine they were off of. I'm just trying to identify what year they are from, but can't really find the right info to determine this. Or if there really is any difference in the many years of 455 manifolds? Casting #s are 1233898 and 383648... strange that there is a difference in the amount of numbers. Can anyone help? Thanks in advance!! :Comp:
From the pics I can tell you they are late 455, probably 74-76. Can't help with the casting numbers, but I think Greg Gessler's site has them listed
The casting date is cast right into the part. What is the number in the dotted circle with the arrow? Your R.H. manifold is correct for 68-72 400,430,455. The number is actually 1383648. The part number 1233899 (not 898) is a one year only number and is correct for '70. If you got these from the same motor, they are from a '70 motor. Matt
Thanks guys... can't quite read the number in the dotted circle in the pics, I'll check it out when I get home. Thanks for the help!
I'll take the exhaust manifolds. Maybe the TCS switch too if nobody is inline yet & the WP if John passes. Need to look check on TCS applications. Will PM.
