So I am 16 and trying to buy a muscle car to restore (yes I don’t care that this will consume the rest of my teenage years) and I came across a 1973 Roadrunner GTX (the guy says it came with the 440 and an automatic originally) which is a roller (no tranny or motor). What are my options for a motor and manual tranny to throw in there? I have to try and get whatever car I get running in 2 months when I need to ship it internationally. What is the cheapest price point for the motor and transmission and what are my options for manual transmissions that’ll fit (I’ve read stuff about t56 swap kits but I figure those are pretty expensive and difficult). The shell itself is 3k and doesn’t look bad at all and I can probably bring the price down a bit.
