is this a good deal?

i was going to offer you my slant six setup as i started reading this but i see you bought it. complete running 74 225 and 904, odometer reads around 70,000, i swapped on a complete 78 supersix setup, opened up the outlet of the exhaust manifold, full 2.5" cutome made single exhaust with super turbo and glasspack resonator, brand new radiator.
