Buddy of mine had a Mustang - I don't remember the exact year or which model, but it had the hood scoop that stayed on the engine when you opened the hood. I think it was a 428??? Don't think it was the Boss, but maybe it was. Anyway, it had the beefy automatic transmission in it. He stomped on it to go around a VW bug on an old chunk of highway at about 30 MPH. Suddenly we were in the opposite lane going sidways in a cloud of smoke from the tires. Don't know who was more scared...me, or the guy in the VW who looked out his side window and saw a Mustang go by sideways, with two pairs of bugged-out eyes touching the windshield. The screeching and squealing was incredible, which mysteriously continued even after he regained control of the vehicle. My buddy eventually discovered the source of the noise and slapped me and told me to shut up. ;-)
Also, wasn't the 1972 Chevelle SS454 the most powerful car to hit the streets? (Horsepower rating, at least?) It wasn't necessarily the fastest, etc, but did have the most 'oomph?' A guy in town had one, and it was something! I do think he got waxed by one of the Boss Mustangs, though. It was a sad day for us Chevy diehards.
I never had a big block, but I did have a screamer that I built on a budget. Bought a 1963 Nova stationwagon for $100. Yanked the 6 cylinder and auto tranny out. Bored a 283 to a 301, 12 to 1 pistons, forged rods, good crank, stock 327 heads (smaller combustion chamber, but I had a true 12 to 1 compression ratio. Didn't like to start in the winter.) Holley 750, dirt track racing cam with hydraulic anti-pump up lifters (hated adjusting solid lifters), Z28 oil pump, 3 speed manual transmission, positraction rear end. Weighed 2900 pounds with me and a tank of gas. It was a real sleeper. Once I got the traction bars adjusted it would snap your head off when I popped the clutch.
You guys that didn't live through the days when those cars were plentiful on the streets really missed out. Luckily there are those folks that are keeping some of them running for us old farts to reminisce about, and for you young guys to dream about.
Real steel....
