So i recently picked up an old military 8v53t, and was wondering what all is unique to it.
I'm aware that obviously the crank and block are unique, as well as the flywheel housing, front cover, blower, and governor, and I've heard that the flywheel is 71 series.
The heads, valve covers, and all 53 series specific components should be shared between it and the 453.
After looking at the service manual and seeing that the firing order is identical to the 453 on each bank, my question is whether the cams are actually shared.
The right bank cam is already on the correct plane to be driven by the timing gears, and the left bank cam could be flipped end for end with a spacer/different timing gear to account for the opposite rotation and offset respectively.
I haven't tore it down yet to make any measurements, and this is the first Detroit I've had the chance to play with, so my experience here is lacking.
Has anyone had the two side by side to see?
Interestingly, the 6v53 seems to have the same thing going on too. Same firing order on both banks as the 353
If anyone is curious, here's a pic of the beast
It looks like it's still in the same configuration as it was in when it was sold by the military. Lots of aluminum used on it, and the flywheel housing is an sae2 with a flex plate in it.
