For your viewing pleasure--or unpleasure....BBC in a Dodge--actually fits real well and a small block gets lost in there. Gobs and gobs of room. BUT...

Not worth it for a cheap swap, as you are finding out. You have to really want it to do it. You can pick up a lower mileage 318 or 360 (prefered in my eyes for what your doing) for around $500 and it would basically bolt in. Get a carbed intake and your there---done, and I am not biased either way for this deal. I am sure you could get a $1,000 for the crate and you'd have every bit of the dollars you need to put a magnum 360 in and make it run. That is doing it cheap AND fast.
