I'm not sure about other years but for 67/68 clearance is very tight around the sides of the engine for spark plug or exhaust work etc. I've also heard they don't handle as well as the small blocks. I personally would prefer the small block but I know the 390's seem to be popular.

I have a 390 in my Mach 1. I love the power this thing makes. They are expensive to build and they have some quirks you have to deal with(Oiling issues etc)but they are reliable and capable of gobs of power. If youa re going to build one I would strongly recommend picking up Steve Christs' FE based book. The information he provides in this book is invaluable to the FE builder.

Changing the plugs or tightening the header bolts can be a real pain! They do weigh more than a small block but don?t all big blocks? If you run an aluminum intake you will save a lot in the weight department because the cast iron ones weigh a ton. I think my fastback handles great with GT springs, front and back sway bars, KYB shocks and 15?-60s.

My '67 has one. I have aluminum heads and intake. The intake is supposed to save about 96 pounds, while the heads about 50, give or take.
If it's true, then the engine wouldn't be much heavier than a stock 351.

I don't think mine handles bad at all, I can take the corners pretty fast when I want to. The real pain is changing the plugs.
I remember when my engine was stock, it would tend to run hot. Since the rebuild and the addition of an oil cooler, it's been great.
