(Newbe) 273 to a 340 and tremec 5speed swap.
@AJ/FormS whew buddy you love to write books. Gotta be short and sweet people don't have the time brother.
@TheCudaKid Looking at the original post again. That engine looks pretty sweet. One thing that jumps out at me is the binder with the documents. Whoever has this engine is anal about documentation which is a good thing. Another thing that's jumping out at me. It's a new engine, with new Edelbrock heads, a very nice looking accessory drive kit, Harlan Sharp rockers. There's a lot of money in this engine already. You might want to ask about receipts for any machining work.
Even ignoring the transmission, $5500 is a steal. No way in hell you could replicate that for $5500 starting from scratch.
Forget about a BB swap, especially if this is a flip car.
