This posting is part a request for information and part a request for help in sourcing date code correct parts.
My car was completed on 02/14/1968, so it is that date that’ll be used for the context of information and parts.
I removed and disassembled the engine back in the mid to late ‘70s with the hopes of rebuilding it because it lacked power and smoked horribly. Beyond that, I did not document anything about the engine identifiers. I stored the useable components and bought a 428CJ.
The PI block was cracked in several places, in the lifter galley, and subsequently scrapped. There is no hope or possibility of getting it back. I’m primarily looking for a suitable block and maybe a connecting rod and maybe an exhaust manifold.
BlockWhat engineering code should I look for; C6ME, C7ME, or C8ME?
What scratch should I look for; A or C?
What date code ranges should I consider? I was thinking that 7L(late), 7M, or 8A(early) might be considered okay? I think an early 7L and a late 8A wouldn't work.
Did the PI block have 2 or 3 web mains and are 3 web mains found only on the C scratch block?
Will “428” be found cast into a water passage covered by one of the core plugs?
Based on the heads (see below), I figure I could use either 7M or 8A(early). Would a 7L be too early for my car?
Crank ShaftWas the 1U crank the only crank used in a '68 GT500?
HeadsThe heads that came off my car’s engine are:
C8AE-H 8A22
C8AE-H 7M26
The 7M26 head has a stamping that I believe may be related to my car’s VIN. The car’s VIN is 8T03S169334-01425. Here is the stamping.
Unfortunately, the stamping is less than ideal, but I read it as 8T1(?)9334.
Connecting RodsThe rods that were in the engine were:
(1) C6AE-C
(7) C7AE-B
Were both the C6AE-C and C7AE-B rods used in the 428 PI in 1968? Do I need to find another C7AE-B, or can I reuse the C6AE-C? Are they interchangeable?
Exhaust ManifoldsThe exhaust manifolds that were on my car were:
C7OE-A 7M29
C8OE-A 7M16 + a spacer
The C8OE-A is cracked, so it'll need to be repaired or replaced.
Crank Shaft Windage TrayDid the 428 PI come with a crank shaft windage tray?
What benefit does it provide?
Lifter Galley Windage TrayDid the 428 PI come with a lifter galley windage tray?
What benefit does it provide? I presume it minimized oil splash on to the aluminum intake manifold.
Any and all help will be appreciated.
