70's era hotrodding...history lesson please

[Mack81]

After many months of constant thinking about what direction I wanna go with this truck I've decided on doing an early 70's-era street freak. I wanna stay period correct as best I can even though I'm 30 and this style was before my time. My good friend has been hotrodding for almost 40 years and he remembers this era of street cars being jacked way up in the rear with shackles and air shocks, slotted mags or crager ss', tunnel ram with a bird catcher, and glass-pack header mufflers like "purple hornies." I have a slightly different idea, but it's best to hear it from the experts.
I have little to no regard for street manners with this thing because it will be at the track 90% of the time running street trophy brackets. I just really want to do it with the 70's flavor and period correct parts. I was raised in the pro-street era so for you guys running the streets in the early-mid 70's, how did you do it?
