I got the build done before I was on the forum, and it's a bit of a story.
The car has been in my family for 35 years...my dad bought it in 1983 the year before I was born, for $300 and an intake manifold. I remember it, it was dad's cool loud car. It wasn't in nearly as good of shape, and I believe it had a 318 at the time. He swapped a 440 six pack setup into it, and it ran like that until the mid 90s when his business took off.
He ended up with another Charger, a 68, and 2 1970 Cuda convertibles. All had 500" stroked 440s, making around 800hp on race gas. But the 70 Charger was always special, and he lavished attention on it.
It got a frame off restoration, a no-expenses-spared paint job, a Dana 60 w/4.10s, and a Mopar Megablock 572". It made about 850hp on race gas. It was always his gnarliest car.
Eventually he had to refresh the motor and bumped it up to 14:1 compression, where it made 870hp at the crank on an engine dyno. That's how it was when he sold it to me 2 years ago.
I couldn't afford the $8/gal 110 leaded gas on the street, so I had thr motor yanked and put to 93 octane specs. It's got a much smaller Comp Cam, I dropped the compression to 10.5:1, and I replaced the cracked crankshaft we discovered with a Scat crank. The top end remained an AED 1000 four barrel and Indy 572-13 heads and a single plane, solid roller lifters, and the displacement is now 580". It made 600rwhp, so roughly 700hp at the crank? Maybe 750.
Since then I've refreshed a few interior items, replaced things like the shocks and a few electrical pieces, but other than that it runs like a top. Starts easy, idles happily at 850rpm, and sounds like a volcano fighting a nuclear explosion at WOT. And it can knock down 15mpg when I need it to.
