Just wrapped up this ProCharged 565 BBC for a no prep customer.
Can’t wait to see this one making passes and putting the power to the ground, through all FOUR tires. 😈

We cut the front off a brand new intake with a Sawzall this morning. 😳
Then stuck it in the mill and started machining the ends of the plenum out of it. 😳😳
Shiny aluminum paperweight or something cool? 👀

🔥Check out this 632 BBC we wrapped up on the dyno last night. This one made 1,200+ horsepower naturally aspirated.🔥
We tested two different carburetors, did some tuning, and worked through the combination to get it where we wanted it.
What would you put it in — dragster, door car, or something else? 🏁
