It seems like it's hard to find information on anything other than factory hot rods and things from roughly '64 and older. I was just wondering if any of you had some insight as to what sort of cam and carb combos people ran back then. I'm not asking for how to make horsepower, just what racers actually tended to use back then. These days people throw around lift and duration like its nothing, but back then without computers or message boards. No comp-cams.com etc. how did a street rodder decide what to put into his engine? Today an off the shelf set of heads can utilize .600" lift and you can run as much duration as you can swallow. I've heard of the duntov 30/30 and it obviously has its serious drawbacks, but it seems like that was some sort of holy grail of cams back then. Though I really have no idea. Same thing with tunnel Rams and high rises. When did this stuff actually start to appear? For example, my cousin may get a barn find 64 ford with a 289 in the next month or so. But it's been hit on the rear. I've seen pictures of race cars from back then like this: And he's interested in fixing it up using old tech of the day, but it's very hard to sort out what is actually old and what is only made to seem old.
