360 Magnum Budget Build Recommendations?

Not quite sure where to start young man? But put your current parts list on hold for right now.....

First off, that's not a "Magnum" engine. Looks more like a 70's/80's 360 LA engine to me, although it may be a 318 with a Thermoquad intake?

You need to find out if it's even usable first, and if it is, make sure it's mounted properly in that chassis.

Then there's the exhaust manifold's? I can't tell what they are by the picture, but I doubt the drivers side will work.

To me, this looks like a much bigger project then you anticipated. Honestly by that pic, it looks like a shell with a engine sitting in it.
