big block stroker build

The 383 based 496 I did a few months ago looks stock (won 1st in '70 Challenger - Stock at Carlisle) and makes 424hp, 468tq to the tires with a hydraulic cam, aftermarket intake, and HP manifolds. He's also driven it to and from Lebanon Valley from Danbury.
We used a Muscle Motors kit (don't think he'd go that way again), Stealth heads (ported by Shady Dell), and a cam from Dwayne @ Porter Racing Heads. He had a bunch of stuff (the 383 only had 800 miles since a complete rebuild from PRH) and gto a wicked deal on the heads but I think if you had nothing it could be duplicated for around $9K plus dyno if you wanted that. Prob be less than $8K using Source parts and supplying a good block.

You'll spend twice what you think for a "completely prepped" block. Sonic testing, main studs, and complete competition quality machining will run closer to $2400.
