GM 270 ci Engines

[jim sewell]

I am trying to find the differences between the engines if any that were fitted to ,

C60X
Staghound
CCKW 6X6
C15TA
The crankshaft on the staghound is different than the CCKW in the Front pulley mounting and crank dog
The staghound block has 4 bolts on the rear main bearing where as the CCKW has 2 bolts
Have not examined a C60X engine but It's engine number starts with 270 #### , same as the CCKW , whereas the staghound starts with ACR#### or ACL#### ( I assume means left and right hand engines ) why did they have left and right hand engines ?
Are the pistons the same ( does some one have a parts book which will give a number for a std piston )
I have seen staghound engines fitted to CCKW and C60X so obviously the blocks are the same .
I would appreciate some information so as to satisfy my curiousity
Regards
