I've posted this before, but here it is again. It's kinda' like what George posted above. This is the perfect way to buy parts.
Many years ago, my Mopar friend Morris worked at a Pizza Hut with a guy who had about a 1970 Nova with a small block. I can't remember his name, so I'll call him "Bob".
One day Bob, who knew nothing about cars, comes in to see Morris at work. "Look at what I bought!" he says & shows Morris a used tunnel ram setup (I think it was a dual quad) that he had bought at the local speed shop.
Morris asks him what he's going to do with it & he says "I'm gonna' put it on my Nova." He then said something about girls goin' for guys with "hot cars" with carbs poking through the hood. Then Morris asks him "What kind of cam are you going to use?"
"Cam?" says Bob, "What's that?"
Morris tells him "You go home & put that on your car & try it out & then come back & we'll talk about what kind of cam you need to run."
Well, they talk it over & one thing leads to another & they decide to pull the motor & rebuild it, since they're gonna' change the cam anyway. Then they have to cut the hood for the manifold to stick through it. Well, now Bob needs a hood scoop, so they put one on. That looks like crap with the scoop a different color than the car, so they decide to repaint the car. After it's painted, Bob drives it for a while & decides he can't live with a tunnel ram. Too big of a PITA to drive on the street, so he pulls it & switches to a performance single four bbl carb & manifold. So now he has a car with new paint, rebuilt motor, & hood scoop, all because of a manifold he's taken off of the car. I don't know if he ever got any girls.
There's no moral here, I just like telling that story.
