FI cam in in 86 or so in trucks. Earlier cars we carbed, better of buying TBI motor and using Edelbrock parts.
It's a 350 chevy with the front 2 holes missing, and some other subtle differences (like not all the expected parts interchange). Very reliable to 200k with maintenance. When they get tired, the RF cylinder is usually too egg shaped to bore, so they throw them away. Which is why rebuilds are more than a 350. Super good engine.
