Thanks Mike but.......,
I'm pretty sure it's the original motor but the air cleaner says 396 350 hp. Any ideas? The 68 came with the option of a 350 hp didn't it?
My original '68 SS is stamped like this on the pad on the block in front of the passenger head.
T 400 EU 8K119978 400=Turbo 400 auto trans EU=350hp 396 cid engine 8K119978=the last digits of the VIN # stamped on the plate on the dash that can be seen through the windshield on the driver's side. This is how you know if you have a #'s matching car (unless someone restamped the motor or VIN) If it's a true SS, the VIN will be 138xxxxx. The 8 denotes the SS option.
Hope this helps.
BL
