408 short block and Indy LAX heads
It is LA based. The cam was a wiped lobe but is a Comp XE high lift 295 hydraulic flat tappet.
This combo ran great in my full street 73 D100. 12.7s to 12.8s here at 2700 feet.
It will need a new cam for sure.
I also have two standard bore 360 blocks in the garage - I would throw one in for the asking price if somebody wants to buy everything and use it to build a new combo.
