Another "Is Fuel Injection a Worthwhile Upgrade?" Question

Yup. Your right because you move the mark every time. Are we talking race car ****, street car ****, mass surface transportation **** or what?

The OE’s use roller cams because the oil formulation was changed. That’s a FACT. To argue that is straight ignorant.

The rest of your post is just more bullshit.

You win. EFI good. Carb bad. Urrrgh

Now I'm not arguing, I'm just stating a fact that I KNOW to be true. My best friend Billy Peyton (RIP) had a 73 440 Challenger he bought NEW right outta high school. First thing he and his cronies did was pull the engine, 12:1, ported 906s, headers, big intake and carb, and a FULL ROLLER valve train. I've seen the pictures. Billy holdin that huge roller in his hand. Just how "far back" was the oil formulation changed? I can remember as a kid, seeing roller cam ads in hot rod mags in the mid 70s. They were stupid expensive fairly new tech, but they were there. I know ultimately as you say, rollers went mainstream across the board because of ZDDP being decreased. But what about "back then"?
