Well, story goes as it was in an 86 IROC Z. The car was disassembled in 97 and the engine was put in dry storage. The car had 66k on it. I did some research and the 5.7 was not offered in 86. So the guy I got it from said, "Maybe it was an 87?". Regardless, it is definitely an 87+ 350. When I pulled the TPI manifold off, I found that they slotted the middle bolts for the different angle. So in fact it was an 86 IROC that had a newer 350 in it. So unfortunately, I do not know the mileage on this one, but it was really clean, and had the letters "CFE" stamped in all 4 corners of the heads. So it was either rebuilt or a savage yard engine. I am leaning towards rebuilt due to not having any temp indicators glued to any freeze plugs or heads.

Specs now are summit dual plane manifold, Edelbrock 1406 carb, summit 1065 cam and new lifters with a new true roller timing chain. The engine has been resealed, cleaned and painted with a single stage urethane in semigloss black.
