Hi Janice, good to hear that your getting that El Camino back into working order. Yeah, the 402 replaced the 396 for the 1970 model year. The 402 is a good engine my father has one in a 1959 Chevy pick up. Man, that engine is strong, pulls like a house, it's out of a 1970 Monte Carlo.
Oh, that was a great story about your dad, I love to hear stories like that. I'm only 20, I've been active in this hobby and online since I turned 16. I hope to someday be able to tell my kids and grand kids what it was like, you know when there was the internet, LOL.
