The 1964 Chevelle Big Block swap is finally ready for fire! But in true hot rodding fashion, the junkyard 454 didn't want to wake up without a fight.

In this video, we're wrapping up the fuel system and putting a budget-friendly carburetor to the test. Evil Energy sent over their Quick Fuel 750cfm 4-Barrel carb for us to try out on this big block Chevy. I'm giving you a full out-of-the-box review, tearing it down to check the internals, and seeing if a budget part can handle a junkyard beast.

🚩 What we cover in this build update:
📌 The Inspection: A complete teardown and first look at the Evil Energy carburetor—is it worth the cash?
📌 The Install: Getting the fuel system plumbed and the carb seated on the 454.
📌 The Screw-Up: We tried to fire it up, but I had the distributor 180 degrees out. Result? A massive backfire through the new carb!

🏁🏁 BONUS: After a quick re-stab of the distributor, you'll get to hear this big block roar to life through open headers for the first time.

If you're into budget builds, DIY engine swaps, and learning from my mistakes, stick around. We are one step closer to driving this thing out of the shop (once we fix the oil leaks).
