If you keep the original block in it and want a little more grunt, a 225 crank and rods will bolt right in the 198 block, pistons are the same 198/225.

I found 3 sheets in my Cuda, 1 in the back seat bottom, 1 in each of the bucket seat backs.

I enjoy seeing restored slant six and 318 cars as much as the HiPo V8s, so yeah, keep the 198 in it.

There is/was an FM3 A93 Barracuda in north GA. The owner posted about it 8-9 years ago on another site, never heard about it since.
